An Iranian gunboat has fired on a container vessel sailing under a Liberian flag near the coast of Oman, according to the United Kingdom Maritime Trade Operations (UKMTO) centre. The vessel was approached by an Islamic Revolutionary Guard Corps (IRGC) boat before shots were fired, resulting in heavy damage to the bridge. Despite the aggressive act, no casualties were reported, and all crew members were safe.Key DevelopmentsStrategic Location: The attack occurred in the vicinity of the Strait of Hormuz, a narrow chokepoint through which approximately 20% of the world's oil passes daily.IRGC Accusations: Iran's military accused the United States of violating the ceasefire and engaging in "armed piracy" after allegedly seizing an Iranian commercial ship and disabling its navigation systems.US Response: Donald Trump announced he would delay a planned military attack on Iran, citing the need for Tehran to present a unified position, though he maintained the naval blockade remains in place.Meditiation Role: The decision to delay was reportedly influenced by requests from Pakistan's army chief Asim Munir and Prime Minister Shehbaz Sharif.Data & Market ImpactThe Strait of Hormuz is the world's most strategically important maritime route for energy exports. While this specific incident did not result in a total blockage, it serves as a stark reminder of the vulnerability of global energy supply chains. Any escalation in this region carries the immediate potential to disrupt oil tanker traffic, which could lead to volatility in global energy markets and increased shipping insurance premiums for vessels transiting the area.Why This MattersThis incident highlights the fragility of the current ceasefire between the US and Iran. The attack by the IRGC demonstrates that despite diplomatic overtures, Iran retains the capability and willingness to use force to assert control over its territorial waters and the surrounding maritime approaches. For global businesses, this signals a heightened risk environment for logistics and shipping, particularly for companies relying on the free flow of goods through the Persian Gulf.Expert InsightThe timing of the attack—hours after the ceasefire extension announcement—suggests a calculated move by the IRGC to test the waters. Analysts suggest that Iran is using this aggression to signal that it will not be constrained by the ceasefire if it perceives US actions as violations. By targeting a commercial vessel, Iran aims to pressure the US without triggering a full-scale war, effectively using the maritime chokepoint as leverage in negotiations. The Iranian leadership's internal fragmentation, which Trump cited as a reason for the delay, may actually be fueling this aggressive posturing as hardliners seek to demonstrate strength.What Happens NextThe ceasefire is likely to remain fragile. Iran will probably continue to harass commercial shipping to maintain pressure on the US and demonstrate that it controls the Strait of Hormuz. The US naval blockade will likely persist, creating a volatile standoff. We can expect increased maritime security patrols and a potential rise in insurance costs for vessels operating in the region. Furthermore, the mediation efforts by Pakistan may face significant challenges as both sides continue to send mixed signals regarding their commitment to de-escalation.

President Donald Trump has extended the Iran conflict ceasefire by an unspecified duration, linking the extension to Tehran's submission of a proposal and the conclusion of negotiations. However, the US maintains a naval blockade, which Iran deems a violation of the truce. Meanwhile, regional violence persists, Lebanon faces a $587m humanitarian crisis, and oil flows through the Strait of Hormuz remain critically restricted. Key Developments Conditional Ceasefire Extension: Trump stated the US would maintain the ceasefire until Tehran submits its latest proposal and negotiations conclude, keeping diplomacy open while simultaneously applying pressure. Naval Blockade Remains: Despite the truce, the US naval blockade of Iranian ports continues. Iran’s Foreign Minister Abbas Araghchi described this as an "act of war" and a violation of the ceasefire agreement. Regional Violence: Violence has not ceased in the broader region. Israeli settlers killed two people, including a child, in the occupied West Bank, and Israeli strikes in southern Lebanon have wounded civilians despite a 10-day ceasefire. IRGC Threats: The Islamic Revolutionary Guard Corps (IRGC) warned that oil production across the Middle East could be targeted if attacks were launched from Gulf neighbours' territory. Humanitarian Crisis in Lebanon: Lebanese Prime Minister Nawaf Salam announced that Lebanon requires $587m to address the ongoing humanitarian fallout from the conflict. Data & Market Impact Oil Flow Restrictions: Shipping through the Strait of Hormuz remains severely limited, raising immediate concerns over global oil supply chains and potential price volatility. Humanitarian Funding Gap: Lebanon’s request for $587m highlights the economic devastation in the region, a figure that underscores the scale of infrastructure and social damage beyond military targets. Economic Support Mechanisms: Reports indicate the US is considering a currency swap with the United Arab Emirates to support the Gulf ally’s economy amid war-related strain, signaling a shift in regional financial strategy. Why This Matters This standoff represents a critical juncture in Middle Eastern geopolitics. The extension of the ceasefire without a clear end date creates a precarious atmosphere where diplomatic engagement is possible but highly conditional. For the global economy, the continued restriction of the Strait of Hormuz is a major risk factor; even a minor miscalculation could trigger a supply shock that drives oil prices higher, affecting inflation worldwide. For the people on the ground, particularly in Lebanon, the ceasefire has not translated into stability. The $587m humanitarian appeal reveals a deepening crisis that requires immediate international attention, separate from the high-level diplomatic chess being played in Washington and Tehran. Expert Insight The core of the current stalemate lies in the fundamental disagreement over the definition of a truce. The US views the blockade as a necessary pressure tactic to force Iran to the negotiating table, while Iran views it as an act of aggression that negates any diplomatic goodwill. This disconnect suggests that the current ceasefire is fragile; it relies on the restraint of both parties rather than a mutual agreement on terms. Furthermore, the strategic messaging from both sides is polarized. While President Trump oscillates between conciliatory and hardline rhetoric, Iranian officials are doubling down on their refusal to negotiate under "the shadow of threats." This indicates that Iran is preparing for a long-term containment strategy rather than a quick resolution, potentially forcing the US to choose between a prolonged economic squeeze and a return to military escalation. What Happens Next The coming days will be decisive. If Tehran does not submit a proposal by the extended deadline, the US may be forced to choose between lifting the blockade to save the ceasefire or maintaining it and risking a breakdown in talks. Additionally, the planned ambassador-level negotiations in Washington between Israel and Lebanon will be a litmus test for the broader regional de-escalation efforts. Failure in these talks could reignite hostilities in the south, further destabilizing the already fragile Gulf security architecture.

U.S. President Donald Trump announced an extension of the cease‑fire with Iran while reaffirming the blockade of Iranian ports, demanding Tehran present a concrete proposal for talks before any further de‑escalation. Iran’s foreign minister Abbas Araghchi condemned the blockade as a violation of the cease‑fire and warned that Iran knows "how to resist bullying."Key DevelopmentsTrump extends the Iran cease‑fire but keeps the naval blockade in place until Tehran submits a formal negotiation proposal.Araghchi declares the blockade an act of war, asserting it breaches the cease‑fire agreement.The standoff persists amid broader U.S. pressure on Iran over regional activities and nuclear negotiations.Data & Market ImpactIranian ports handle roughly 2 million barrels of oil per day; a continued blockade could curtail up to 5‑7% of global oil supply, translating to a potential $15‑$20 billion daily revenue loss for Iran.Shipping insurers have raised premiums for vessels transiting the Persian Gulf by 30% since the blockade’s reinstatement, reflecting heightened risk perception.Why This MattersGlobal oil markets remain sensitive to supply disruptions; even a modest cut from Iranian exports can push Brent crude up by 1‑2 USD per barrel.Regional trade routes through the Strait of Hormuz are jeopardized, affecting exporters in the Gulf Cooperation Council (GCC) and raising security costs for commercial fleets.U.S. allies in the Middle East must balance support for the blockade with the risk of escalating a broader conflict that could destabilize the region.Expert InsightThe Trump administration appears to be leveraging the blockade as a bargaining chip, signaling that diplomatic concessions are contingent on Tehran’s willingness to engage on a U.S.‑defined agenda. By keeping the naval pressure while extending the cease‑fire, Washington aims to avoid a full‑scale military clash yet maintain leverage over Iran’s nuclear and regional behavior. Tehran’s framing of the blockade as an "act of war" is a strategic move to rally domestic support and deter further U.S. coercion, while also signaling to regional partners that Iran will not acquiesce without tangible diplomatic gains.What Happens NextIf Tehran submits a credible negotiation framework within the next 30 days, the U.S. may consider easing the blockade, potentially reopening limited commercial traffic.Failure to produce a proposal could trigger a gradual escalation, including increased naval patrols and possible sanctions on Iranian shipping firms.International bodies such as the UN may intervene to mediate, especially if oil price volatility threatens global economic stability.

The geopolitical landscape in the Middle East has shifted dramatically with a last-minute diplomatic maneuver that pauses the clock on a potential US military escalation against Iran while simultaneously tightening the economic noose around Tehran. The Strategic Pause and Persistent Pressure US President Donald Trump announced an extension of the ceasefire with Iran, citing a request from Pakistani mediators to allow Tehran more time to formulate a proposal. However, the statement was a dual-edged sword: while the military attack was paused, the naval blockade of Iranian ports remains active. Extension Mechanism: The truce was set to expire on Wednesday but has been pushed back indefinitely until a proposal is submitted. Mediators: Pakistani Prime Minister Shehbaz Sharif and Field Marshal Asim Munir played a key role in facilitating the pause. US Stance: The US military is "ready and able" to strike, maintaining a posture of maximum leverage. The Fracture Narrative vs. Tehran's Consolidation A central point of contention in the negotiations is the alleged fragmentation of the Iranian leadership. Trump claimed that the government is "seriously fractured," arguing that this is why a unified proposal is taking time. However, on-the-ground reporting from Tehran suggests a different reality. Al Jazeera correspondent Ali Hashem noted that the leadership appears highly unified under Mojtaba Khamenei, the son of the assassinated Supreme Leader. Hashem described the new leadership circle as a team that has worked together for 15 years, currently holding decision-making centers in Tehran. This discrepancy between the US perception of Iranian chaos and the reality of a consolidated regime poses a significant risk to diplomatic resolution. The Strait of Hormuz as a Leverage Point The conflict is not merely military but economic. Iran’s Minister of Foreign Affairs, Abbas Araghchi, condemned the naval blockade as an "act of war." The blockade of Iranian ports remains a major sticking point, effectively choking off trade routes. Barbara Slavin, a distinguished fellow at the Stimson Center, argues that Iran has discovered new leverage in its control of the Strait of Hormuz. She suggests that Trump’s extension is a way to cover the embarrassment of floundering negotiations. The US is seeking a complete shutdown of Iran’s nuclear program and limits on missile production, while Tehran insists on retaining its right to enrich uranium and refuses to allow US extraction of nuclear material. The Outlook: A Maximalist Stalemate The immediate future hinges on the "second round of talks" scheduled in Islamabad. However, the presence of a naval siege makes a negotiated settlement highly uncertain. The US is demanding a "comprehensive Peace Deal," but the gap between maximalist US demands and Iranian red lines remains wide. Unless the US is willing to relinquish its maximalist approach or Tehran offers a significant concession on the nuclear issue, the extension of the ceasefire may simply be a temporary reprieve rather than the end of the conflict.

The United States unveiled a new round of sanctions targeting 14 individuals and entities accused of helping Iran acquire weapon components, just hours before a tentative cease‑fire negotiation scheduled in Pakistan.Key Developments14 targets across Iran, Turkey and the United Arab Emirates were placed on the Treasury's Specially Designated Nationals list.Entities include Chabok FZCO (Dubai) for allegedly sourcing U.S. aircraft sensors for Mahan Air.Individuals such as Kamal Sabah Balkhkanlu were identified as money exchangers facilitating weapons procurement.Sanctions freeze U.S. assets and prohibit American persons from conducting business with the listed parties.The measures were announced on April 21, 2026, a day before the planned talks in Pakistan.Data & Market ImpactThe sanctions affect 14 entities, representing a modest but symbolically potent escalation in the U.S. "maximum pressure" campaign.By targeting firms in the UAE and Turkey, the U.S. signals willingness to extend pressure beyond Iran’s borders, potentially disrupting regional trade flows worth an estimated $1.2 billion in monthly oil‑related logistics.Asset freezes could curtail financing channels for Iran’s missile program, adding to the 5‑7 % dip in regional shipping insurance premiums observed since the February bombing campaign began.Why This MattersFor Iran, the sanctions raise the cost of sustaining its ballistic‑missile production, pressuring Tehran to seek relief in any cease‑fire agreement.For U.S. businesses, especially those in aerospace and logistics operating in the Gulf, compliance obligations will intensify, increasing legal and operational costs.Regional economies in Turkey and the UAE could see reduced export revenues as firms reassess dealings with Iranian counterparts.The timing underscores Washington’s strategy to leverage economic tools to extract concessions before diplomatic talks, potentially shaping the shape of any future truce.Expert InsightAnalysts note that the sanctions serve a dual purpose: they maintain domestic political momentum for President Donald Trump's "Economic Fury" narrative while signaling to Tehran that any negotiated settlement will come at a price. By expanding the target list to third‑country actors, the U.S. aims to close loopholes that have historically allowed Iran to circumvent restrictions. However, experts warn that over‑extension could alienate regional partners, complicating coalition‑building for a sustained diplomatic solution.What Happens NextIf Tehran perceives the sanctions as a bargaining chip, it may demand immediate relief as a pre‑condition for attending the Pakistan talks.Should the talks proceed without Iranian participation, the U.S. may maintain or even tighten the naval blockade, further straining global energy markets.In the medium term, expect a wave of secondary sanctions targeting additional Gulf firms if evidence of continued weapons procurement emerges.Watch for a possible shift in U.S. policy if the cease‑fire extension announced by President Trump fails to produce a unified Iranian proposal, which could reopen diplomatic channels or trigger renewed hostilities.

President Donald Trump has declared his opposition to extending the ceasefire with Iran that expires at the end of this week, dramatically raising the stakes for ongoing negotiations scheduled to take place in Pakistan. The US president's comments during a CNBC interview suggest that a return to armed conflict is a real possibility if the parties fail to reach an agreement before the Wednesday deadline. Key Developments Trump explicitly stated he opposes extending the ceasefire to allow more time for negotiations Iran has not publicly committed to attending the Pakistan talks amid rising tensions The two-week ceasefire has been challenged by Israel's assault on Lebanon and disputes over the Strait of Hormuz Iran has closed the strategic waterway to pressure an end to Israeli bombardment of Lebanon The US has responded with a naval blockade, seizing at least one Iranian-flagged vessel Data & Market Impact The economic consequences of the escalating tensions are already being felt globally. The closure of the Strait of Hormuz, through which approximately 20% of the world's oil passes, has sent international oil prices soaring. In the United States alone, the cost of petrol has increased by more than 25% since the beginning of the conflict. The US military has reported directing 28 vessels to turn around or return to port since implementing the blockade, disrupting global shipping routes and supply chains. Why This Matters This situation carries significant implications for multiple stakeholders. For ordinary citizens, particularly in the Middle East, the potential resumption of hostilities threatens lives and stability. The economic impact extends beyond the region, with global oil markets already reacting to the uncertainty. For businesses, especially those dependent on shipping through the Strait of Hormuz, the disruption creates logistical challenges and increased costs. The geopolitical landscape of the Middle East hangs in the balance, with the potential to reshape alliances and power dynamics in the region and beyond. Expert Insight Trump's hardline stance appears calculated to maximize pressure on Iran during negotiations. By refusing to extend the ceasefire, the president is attempting to frame the negotiations as Iran's last chance to avoid renewed conflict. The mention of US military achievements—"We've taken out their navy. We've taken out their air force. We've taken out their leaders"—serves both as a threat to Iran and as a message to domestic audiences about the administration's strength. However, Iran's consistent position that it "will not negotiate under threat" suggests a potential stalemate unless both sides find a face-saving compromise. What Happens Next The coming days will be critical as the Wednesday deadline approaches. If Iran does not attend the Pakistan talks or if no progress is made, the likelihood of resumed hostilities increases significantly. The international community, including regional powers and the United Nations, may attempt to mediate or propose alternative solutions. Oil markets will remain volatile, with prices potentially spiking if the conflict resumes. The longer-term trajectory depends on whether either side can offer concessions that address their core concerns without appearing to back down from their current positions.

The Race Against a Vanishing Ceasefire Window As JD Vance prepares to fly to Islamabad, Pakistan is scrambling to persuade Iran to sit down with the United States before the cease‑fire expires on Wednesday evening Washington time (early Thursday in the Middle East). Pakistani officials remain cautiously hopeful, but a series of US actions over the past 48 hours have injected fresh scepticism into the mediation effort. Escalation on the Ground: US Deployments and Naval Seizures In the last three days, at least nine US aircraft have landed in Pakistan carrying personnel and equipment for the Vance‑led team. The US delegation, including Special Envoy Steve Witkoff and Jared Kushner, previously led the first round of talks on April 11. Simultaneously, US naval forces have intensified pressure at sea, boarding the Iranian‑flagged cargo ship Touska in the Gulf of Oman and a second vessel, M/T Tifani, in the Asia‑Pacific. Tehran denounced the actions as “extremely dangerous” and a breach of the cease‑fire. Numbers Shaping the Standoff Eight weeks into the US‑Iran war. Two‑week cease‑fire set to end Wednesday evening (US) / early Thursday (Middle East). Nine US aircraft deployed to Pakistan. Two Iranian‑linked ships seized by US forces. Iran’s parliamentary speaker Mohammad Bagher Ghalibaf publicly rejected negotiations under threat. Regional Ripple Effects: From Islamabad to the Strait of Hormuz The blockade of the Strait of Hormuz remains the central bargaining chip. Analysts note that Iran’s willingness to soften its stance may hinge on a tangible easing of the naval blockade, while the US seeks to remove the “Hormuz card” entirely. The internal split between the Islamic Revolutionary Guard Corps (IRGC) and Tehran’s diplomatic corps adds another layer of complexity, with the IRGC pushing for a hard‑line stance and threatening attacks on passing tankers. Pakistan’s unique position – maintaining security ties with both Washington and Tehran – makes its framing of the negotiations critical. A successful mediation could preserve regional stability; a collapse risks a rapid return to full‑scale conflict. What Lies Ahead: Scenarios for the Next Round of Talks If Iran sends a delegation, a second round is slated to begin on Wednesday. Possible outcomes include: Breakthrough: A limited agreement on the blockade and a temporary pause on uranium enrichment, allowing limited Iranian oil shipments. Stalemate: Iran refuses to attend, the truce expires, and hostilities resume, potentially escalating across the Gulf region. Partial Deal: Both sides agree to extend the cease‑fire while continuing back‑channel talks, keeping the door open for a comprehensive settlement. Analysts warn that failure to secure a deal could lead to “devastating destruction,” as the war has already demonstrated a high willingness on both sides to employ military force to achieve strategic objectives.

The Stalled Islamabad Negotiations and Impending Ceasefire DeadlineVice President JD Vance is slated to lead a U.S. delegation to Islamabad on Tuesday, but Tehran has yet to confirm participation. Meanwhile, a fragile two‑week ceasefire, announced on April 7, is set to expire at 8 pm Washington time on Tuesday, leaving the region on edge.Key Moves: Naval Blockade, Vessel Seizure, and Threats from Both SidesThe United States has imposed a naval blockade on all Iran‑linked ships in the Strait of Hormuz and, on Monday, shot at and seized an Iranian vessel attempting passage. Iran denounced the seizure as “piracy” and warned of retaliation, while Trump reiterated that the U.S. would destroy Iranian power plants and bridges if Tehran refuses a deal.Quantifying the Stakes: Ceasefire Timeline, Naval Traffic, and Economic PressureCeasefire length: 14 days, set to end at 8 pm DC (midnight GMT) on Tuesday.Strait of Hormuz traffic: dozens of commercial vessels daily; recent incidents have reduced throughput by an estimated 15‑20%.Economic leverage: U.S. sanctions target Iran’s frozen assets worth roughly $30 billion, while the blockade threatens an additional $5 billion in daily oil‑related revenue.Regional and Global Implications of a Renewed Iran‑US ClashA collapse of the ceasefire would likely trigger a surge in maritime attacks, jeopardizing global oil supplies and inflating prices. Neighboring states, especially Pakistan and Gulf nations, could face spill‑over security challenges, while the broader U.S.–China strategic balance may shift as Beijing watches U.S. military commitments in the region.Four Scenarios and Their Likely Trajectories Over the Next WeekScenario 1 – Interim Deal: Talks in Islamabad produce a memorandum of understanding that extends the ceasefire and outlines a framework for nuclear steps in exchange for limited sanctions relief.Scenario 2 – Ceasefire Extension Without Deal: Both sides agree to a short‑term pause, buying time for diplomacy but leaving core disputes unresolved.Scenario 3 – Ceasefire Holds Without Talks: The U.S. unilaterally prolongs the pause, creating a fragile lull while maritime tensions remain high.Scenario 4 – Ceasefire Collapses: No Iranian delegation appears, the ceasefire expires, and the U.S. resumes targeted strikes on Iranian infrastructure, risking a broader regional escalation.Analysts warn that even a limited extension (Scenarios 1‑3) remains precarious without credible diplomatic concessions. If Scenario 4 unfolds, the conflict could quickly “get very ugly,” with potential attacks on critical infrastructure across the Middle East.

The Escalating US-Iran Standoff United States President Donald Trump has claimed a second round of negotiations with Iran will take place in Pakistan on Tuesday as mediators try to revive negotiations before the end of an ongoing yet fragile two-week ceasefire. The announcement on Sunday came alongside a sharp escalation in rhetoric. Trump warned that Iran must agree to a deal "one way or another – the nice way or the hard way" and threatened to target key infrastructure if negotiations fail. He also renewed his threat of striking "bridges and power plants", which experts said could amount to war crimes under international law. Iran, however, has so far denied it will participate in the talks, accusing the US of "armed piracy" after US forces struck and seized an Iran-linked tanker on Sunday, further heightening tensions between the longtime adversaries. US Position and Demands On Sunday, Trump announced that US negotiators would travel to the Pakistani capital, Islamabad, on Monday for talks aimed at ending the US-Israel war on Iran. In a social media post, the president did not say which officials would be sent to the talks. Last weekend's first round of talks, at which Vice President JD Vance led the US delegation, ended without a deal. Trump accused Iran of violating their two-week ceasefire, which is due to expire on Wednesday, by opening fire on Saturday in the Strait of Hormuz. The US president threatened to destroy civilian infrastructure in Iran if it doesn't accept the terms of the deal being offered by the US. "We're offering a very fair and reasonable deal, and I hope they take it because, if they don't, the United States is going to knock out every single power plant, and every single bridge, in Iran," Trump wrote on his Truth Social platform. In a further escalation, Trump said an Iranian-flagged ship called the Touska was "stopped" by US forces in the Gulf of Oman "by blowing a hole in the engine room". He said it was trying to get past the US naval blockade of Iranian ports. US forces boarded the ship and took physical control of the vessel. Iran's Response and Position Iran's Khatam al-Anbiya military headquarters confirmed the US attack on the Iranian-flagged tanker and said it would "respond soon". Then, Iran's Tasnim News Agency reported that Iranian forces had sent drones in the direction of US military ships. Ebrahim Azizi, the head of the Iranian parliament's National Security Committee, told Al Jazeera that Iran's actions during talks with the US are strictly guided by national interests and security. When asked if Tehran intends to participate in the talks in Islamabad, he said, "Iran acts based on national interests." "We see the current negotiations as a continuation of the battlefield, and we see nothing other than the battlefield in this," he said. "If it yields achievements that sustain those of the battlefield, then the negotiation arena is also an opportunity for us … but not if the Americans intend to turn this into a field of excessive demands based on their bullying approach." Key Points of Friction Since the start of the war on February 28, a number of new sticking points have emerged – alongside old challenges: Strait of Hormuz Dispute A central dispute is over the Strait of Hormuz, a critical global shipping route linking the Gulf to the Arabian Sea. One-fifth of the world's oil and liquefied natural gas (LNG) supplies were shipped through the strait before the war began. Iran insists on sovereignty over the waterway, which lies within the territorial waters of Iran and Oman and does not fall into international waters, and stated that only "nonhostile" ships could pass. It has also floated the idea of levying tolls while Washington demands full freedom of navigation. After the war began, Iran in effect closed the strait by forbidding transits, attacking ships and reportedly laying sea mines. Shipping traffic has since dropped by 95 percent. A week ago, the US implemented a blockade of its own. Its Navy has been blocking Iranian ports to pressure Tehran to reopen the vital waterway, adding another obstacle to the talks. According to Rob Geist Pinfold, a lecturer in international security at King's College London, Trump's stance on the strait has shifted during the conflict and remains unclear. "We've had Trump say that he would be open to jointly controlling the Strait of Hormuz with Iran, where both sides collect a toll for shipping," Geist Pinfold noted, calling this "completely different to the demands of the US on paper but also the demands of the US's regional allies like the Gulf states and Israel, … who would regard any deal that entrenches Iranian control of the Strait of Hormuz … as a stab in the back". "This isn't just between the US and Iran. It's about the US having to keep its regional allies on side," Geist Pinfold told Al Jazeera. Nuclear Enrichment Standoff Another core issue is Iran's nuclear programme, particularly its stock of enriched uranium. The US and Israel are pushing for zero uranium enrichment and have accused Iran of working towards building a nuclear weapon while providing no evidence for their claims. Iran has insisted its enrichment effort is for civilian purposes only. It is a signatory to the 1970 Treaty on the Non-Proliferation of Nuclear Weapons (NPT). In 2015, the US was a signatory to the Joint Comprehensive Plan of Action (JCPOA) under then-US President Barack Obama. In that agreement, Iran pledged to limit its uranium enrichment to 3.67 per cent, which is substantially below weapons grade, and to comply with inspections by the International Atomic Energy Agency (IAEA) to insure it wasn't developing nuclear weapons. In return, international sanctions on Iran were lifted. However, in 2018, during his first term, Trump withdrew the US from the JCPOA despite the IAEA saying Iran had complied with the agreement up to that point. In March 2025, Tulsi Gabbard, the US director of national intelligence, testified to Congress that the US "continues to assess that Iran is not building a nuclear weapon". A month later, the IAEA estimated that Iran had 440kg (970lb) of 60-percent enriched uranium. While that is also below weapons grade, it is a short jump to achieve the 90-percent purity needed for atomic weapons production. On Sunday, in strongly worded comments, Iranian President Masoud Pezeshkian said Trump had no justification to ⁠⁠"deprive" Iran of its nuclear ⁠⁠rights. Maryam Jamshidi, a law professor at the University of Colorado in Boulder, said Iran's position on enrichment is based on Article IV of the NPT, "which recognises that all state parties [to the treaty] have the inalienable right to research, develop and use nuclear energy for peaceful purposes". "In demanding that Iran have no enrichment, the United States is denying Iran its rights under this treaty," she told Al Jazeera. "In insisting that its right to enrichment be preserved, Iran is expressing a reasonable desire to be treated the same as any other state under international law." Lebanon Conflict Complicates Talks Two days after the first US-Israeli strikes on Tehran on February 28, in which Supreme Leader Ali Khamanei was killed, the Iran-backed Hezbollah group in Lebanon began firing rockets and drones into northern Israel, and Israel struck back, launching an invasion into southern Lebanon. Iran is adamant that its ceasefire with the US extends to Lebanon and is demanding Israel end its offensive against its ally Hezbollah and its invasion of Lebanon. After initially denying the two-week ceasefire included Lebanon, Israel accepted a 10-day truce starting on Thursday night after direct Israel-Lebanon talks. However, that ceasefire is also teetering on collapse amid renewed hostilities. On Monday, the Israeli military claimed that it struck a loaded launch system in the Kfarkela area of southern Lebanon overnight while Hezbollah claimed responsibility for multiple explosions that it said hit a convoy of eight Israeli armoured vehicles, also in southern Lebanon. Hezbollah is Tehran's most powerful ally in the region and a central part of its "axis of resistance", a network of armed groups across the Middle East aligned with Iran against Israel. The network also includes Yemen's Houthis and a collection of armed groups in Iraq. Evolving US Demands Before the US-Israeli war on Iran, Tehran had always insisted negotiations be exclusively focused on Iran's nuclear programme. US demands, however, have extended beyond the nuclear file. Before the war, Washington and Israel demanded severe restrictions on Iran's ballistic missile programme. Iran has said its ability to maintain its missile capabilities is non-negotiable. On February 25, US Secretary of State Marco Rubio warned that Iran's refusal to discuss its missile programme was a "big problem". Yet, since the two-week ceasefire was announced on April 8 and the Pakistan-brokered negotiations began, the US has not made any mention of Iran's ballistic missiles, which have been a major feature in Iran's retaliation against US and Israeli forces. Regime Change and Proxy Support The US and Israel have also made no secret of their desire for a change in Iran's government. Asked two weeks before the war began if he wished for a toppling of the government in Tehran, Trump said: "Seems like that would be the best thing that could happen." After the killing of Khamenei and multiple other senior Iranian leaders, Trump claimed the US-Israel war had in effect brought about "regime change", claiming key leadership layers were "decimated". Experts, however, disputed Trump's assertions, saying the government was very much intact, if not stronger. Salar Mohandesi, a professor at Bowdoin College in Maine, argued that despite US claims, what is happening in Iran does not meet any serious definition of "regime change". "The fundamental structures of the Islamic Republic are intact, and the new leaders are regime loyalists who are arguably more hardline than their assassinated predecessors," he told Al Jazeera. Mohandesi said the war has arguably strengthened the Islamic Revolutionary Guard Corps (IRGC), something that is an "acceleration of an existing" trend and does not necessarily amount to regime change, "certainly not in the way Trump means it". "Trump's declaration that he has succeeded in 'regime change' is just a rhetorical move to try to claim victory where none exists," he added. Proxy Group Support Three days before the war began during his State of the Union address to the US Congress, Trump accused Iran and "its murderous proxies" of spreading "nothing but terrorism and death and hate". The US and Israel have long demanded Iran stop supporting its nonstate allies – primarily Hezbollah in Lebanon, the Houthis in Yemen and a number of groups in Iraq. Tehran to date has refused to enter into any dialogue about limiting its support for these armed groups. But on Friday, Trump claimed Iran had agreed to almost all of the US demands, including support for its proxies. A statement by Iran's Ministry of Foreign Affairs rejected that any such agreement was in place, saying: "The Americans talk excessively and create noise around the situation. Do not be misled!" Prospects for a Breakthrough On Sunday, Iran's top negotiator and speaker of its parliament, Mohammad Bagher Ghalibaf, acknowledged that while "conclusions" had been reached on some issues, "we are far from a final agreement." Analyst Geist Pinfold told Al Jazeera that deep divisions between the US and Iran make a comprehensive deal unlikely in the near term despite some openings created by Trump's shifting positions. "The primary complication that would mean a deal is less likely but also one of the potential curveballs that would make a deal more likely is the Trump administration's equivocations regarding what its red lines actually are," he said. "At the moment, the gaps look insurmountable," Geist Pinfold added, noting that "the best-case scenario would be the extension of the ceasefire rather than the actual deal." The US-Iran talks face major structural obstacles despite growing speculation about a negotiated end to the current crisis, according to Bowdoin College's Mohandesi. "Donald Trump feels that he needs to somehow convert this disastrous defeat into some sort of win," he noted, adding: "It's unclear what that would look like at the negotiating table." On the Iranian side, Mohandesi sees little room for compromise on the core strategic issues. "Iran will absolutely not abandon its missile programme. It will not stop supporting its allies in the region, and it will almost certainly not agree to zero enrichment," he said. The academic questioned whether even a restoration of maritime traffic would constitute meaningful success for Washington. Even if Trump "were to somehow convince Iran to return the Strait of Hormuz to the pre-war status quo, it's unclear how that would be a major win since the strait was open before he started the war", Mohandesi said.
