The Munition Shortage The United States has enough munitions for any plausible scenario in the Iran war, but rebuilding its depleted inventories will “take years”, according to a new report by the Center for Strategic and International Studies (CSIS). Replenishment Timeline Restoring pre-war stockpiles of four critical munitions heavily used by US forces during nearly 40 days of joint fighting with Israel against Iran would take at least two years – and in some cases more than three – the Washington-based think tank said on Wednesday. Land Attack Missile (TLAM) Terminal High Altitude Area Defences (THAAD) interceptors Patriot missiles SM-3 and SM-6 ship-based surface-to-air missiles The Data Analysis The report noted that while US officials publicly project confidence in weapons stockpiles, analysts have said that dwindling munition supplies may be shaping Washington’s calculations over whether to resume the war on Iran. The Impact Analysis “Campaigns against Iran and its proxies – and, for Patriot interceptors, aid to Ukraine – have made the problem more acute,” said the CSIS report. “Alongside replenishing its own stocks, the United States also has to fulfil orders from allies and partners.” The Prediction “Decisions on how to allocate new production have already created bilateral friction, and this friction will continue for the next few years as demand outpaces supply,” the report warned. The main problem is not funding but production time, limited manufacturing capacity and long procurement lead times, with CSIS noting that past procurement levels were relatively low for many systems, slowing replacement efforts despite recent increases in defence spending.

Executive Overview: Ukraine’s Tactical Edge in Mid‑2026Ukraine is currently leveraging a combination of fresh Western weaponry, improved command‑and‑control systems, and Russian supply‑chain disruptions to claim a short‑term advantage on key sectors of the front line. Frontline Shifts: Gains Around Bakhmut and the DonbasLate April 2026: Ukrainian forces recaptured several villages north of Bakhmut, tightening pressure on Russian defensive lines.May 2026: A coordinated assault in the southern Donbas pushed Russian positions back by roughly 5‑7 km, marking the deepest Ukrainian advance since 2023.Russian artillery units report ammunition shortages, limiting their ability to conduct sustained counter‑barrages. Western Military Aid: Quantifying the Boost$2.5 billion in new aid approved by NATO in March 2026, including additional HIMARS rockets, air‑defence batteries, and armored personnel carriers.Delivery of 12 new Patriot missile batteries enhances coverage over Kyiv and critical infrastructure.Training programs accelerated, with 5,000 Ukrainian soldiers completing joint drills on Western platforms since January 2026. Strategic Ripple Effects Across Eastern EuropeThe perceived Ukrainian advantage reshapes regional calculations. NATO members cite the progress as justification for further funding, while Russia faces heightened diplomatic isolation and internal pressure to reassess its war strategy. Future Outlook: Sustainability of the AdvantageShort‑term: Continued Western deliveries are likely to sustain momentum through the summer.Medium‑term: Russian adaptation—particularly in logistics and drone warfare—could erode the edge by late 2026.Long‑term: A decisive Ukrainian counter‑offensive hinges on maintaining supply lines and avoiding attrition spikes.

The Stark Divide in War Cost EstimatesUnited States Defense Secretary Pete Hegseth has clashed with American lawmakers over the cost of war on Iran in his first appearance on Capitol Hill since the conflict – now into its third month – broke out. The Pentagon told a hearing of the House Armed Services Committee that the US had spent $25bn on its war on Iran, largely on munitions and equipment maintenance. But Democratic leaders and several economists believe that number to be a significant underestimate, with actual costs potentially reaching between $630bn and $1 trillion.The Pentagon's Limited Financial DisclosureThe Pentagon's acting comptroller, Jay Hurst, who testified alongside Hegseth and Joint Chiefs of Staff Chairman Dan Caine, presented the estimated figure of $25bn to the committee. "We will formulate a supplemental [on additional funding], through the White House, that will come to Congress once we have a full assessment of the cost of the conflict," Hurst said, promising to provide a cost breakdown later.The estimated figure only reflects "the costs of the war," Hurst explained, factoring in "munitions expended in that total and other operational costs." This figure is significantly smaller than the $200bn initially requested by the Trump administration for the war and the $11.3bn reported for just the first six days of fighting in March.The Economic Ripple Effects Beyond Direct Military SpendingAs the US continues with its blockade of Iranian ports and Tehran controls the Strait of Hormuz, gas prices in the US have hit a new high at $4.23 a gallon – the highest since 2022, when Russia invaded Ukraine. The Brent crude benchmark has been trading above $120, leading to a 40 percent rise in gas prices compared to pre-war levels.Representative Ro Khanna claimed the war would cost about $631bn – or some $5,000 per household – to the US economy due to increased gas and food prices. "Your $25bn number is totally off," Khanna told Hegseth, highlighting the administration's failure to account for broader economic impacts.The rising cost of living has also affected Trump's approval rating, hitting a record low in his second term with only 22 percent of Americans approving of his handling of cost of living, according to a Reuters/Ipsos poll.Hidden Costs of War: Infrastructure and Long-term ImplicationsThe US claimed earlier that it struck more than 13,000 targets over the first 39 days of fighting with Iran. For context, the US fired more Patriot missiles in the first four days of the Iran war than it supplied to Ukraine over the past four years, with each missile costing $4m.However, the economics and impact of the war extend far beyond the worth of bombs and missiles. One major expense is reconstructing and repairing damaged assets. After the US-Israeli strikes assassinated former Supreme Leader Ali Khamenei, Iranian strikes caused damage to US military camps in Kuwait, alongside other military bases in the UAE, Saudi Arabia, Jordan, and Bahrain.Earlier this month, NBC News quoted six US officials noting that Iran damaged US military bases and equipment in the Middle East far worse than publicly acknowledged. The damages alone could lead to billions of dollars in repairs, with one report estimating that repairs to the US Navy Fifth Fleet headquarters in Bahrain could cost $200m alone.Historical Precedents and Future ProjectionsHarvard economist Linda Bilmes had estimated in February 2006 that the Iraq war would cost the US $3 trillion, when the George Bush administration was telling the public that fighting would cost $50bn. Twenty years later, Bilmes ended up with among the most accurate predictions, as the Iraq war's total cost is now estimated at $2 trillion."Wars always cost more than expected. Throughout history, those who get into wars tend to be optimistic about the cost and about the length of time it will take," Bilmes noted. "It is hard to measure the exact cost. But based on what we know now, it [the current Iran war] is costing about $2bn a day in short-term, upfront costs, which is the tip of the iceberg."Beyond immediate expenses, Bilmes highlighted long-term costs including veterans' care and restocking weapons inventory. "I am certain we will reach one trillion dollars for the Iran war," she concluded. Meanwhile, the Trump administration has asked for a $1.5 trillion defense budget for next year – a 42 percent increase, or the largest expansion in military spending since World War II.

Ukraine and Germany have agreed on a strategic defence partnership that will enhance cooperation in drone production and bolster Kyiv's air defences. Ukrainian President Volodymyr Zelenskyy and German Chancellor Friedrich Merz announced the deal at a news conference in Berlin.The partnership will grant Germany access to Ukraine's advanced drone technology, developed during its conflict with Russia, in exchange for additional military support from Germany. This cooperation will cover various types of drones, missiles, software, and modern defence systems.In a joint declaration, the two countries stated they will strengthen cooperation in the air defence field. Germany will support Ukraine's drone industry and establish drone co-production ventures. The German defence ministry has agreed to fund contracts for several hundred Patriot missiles from the United States, which Ukraine urgently needs to counter nightly Russian drone and missile attacks.Ukrainian Defence Minister Mykhailo Fedorov expressed gratitude to his German counterpart, Boris Pistorius, for the package, which he valued at four billion euros ($4.7 billion). This funding will provide a massive boost for Ukraine's air defence, protecting its cities and critical infrastructure.Ukraine currently has the production capacity to manufacture twice as much military equipment as it is deploying but lacks the necessary funding. President Zelenskyy emphasized that financial constraints hinder Ukraine's ability to scale up production.German Chancellor Merz noted that the deal is mutually beneficial, citing Ukraine's battle-tested military as a valuable asset for European security. The agreement also includes the exchange of digital combat data for developing new weapons systems.The announcement comes as hopes rise that the European Union may soon provide Ukraine with a 90-billion-euro ($105bn) loan, which was blocked by Hungary last month. With the recent election of Peter Magyar in Hungary, who is expected to reverse this stance, Ukraine's financial prospects are improving.The urgency of Ukraine's need for additional arms was highlighted by a missile attack on the city of Dnipro, which killed four people and injured at least 21. Russian troops have also captured territory in the Dnipropetrovsk region and launched attacks in the city of Kherson.

Ukraine is facing a critical spring as the country's situation continues to deteriorate. US financial support has dried up under Donald Trump, making European aid crucial. However, Hungary's Prime Minister Viktor Orbán is blocking a €90bn EU loan to Kyiv, causing exasperation for Ukrainian President Volodymyr Zelenskyy.Orbán's opposition is driven by his nationalist base and allegations of collusion with Russia to undermine European decision-making. With US attention shifting to the Middle East, Ukraine has become more vulnerable and reliant on European support. Higher oil prices and the lifting of restrictions on Russian oil have boosted Vladimir Putin's war economy, while stocks of US Patriot missile interceptors are dwindling.Meanwhile, peace negotiations with Moscow have paused, and the White House's priorities in the Gulf are taking precedence over Kyiv's needs. Ukraine's president has stated that future US security guarantees are being linked to the surrender of unoccupied territory in the Donbas. Europe must develop stronger mechanisms to counter blocking tactics like Orbán's and provide crucial financial support to Ukraine.

Ukrainian President Volodymyr Zelenskyy has concluded defence agreements with the United Arab Emirates (UAE) and Qatar, focusing on joint expertise in countering threats from missiles and drones. The agreements were made during Zelenskyy's visit to Doha and the UAE earlier in the day. The defence pact with Qatar includes collaboration in technological fields, development of joint investments, and the exchange of expertise in countering missiles and unmanned aerial systems. This move comes as Iran continues to attack its Gulf neighbours, with Tehran insisting it targets only US assets in retaliation for the US-Israeli war on Iran. Ukraine has deployed 201 anti-drone experts to the Middle East to help Gulf nations counter Iranian drones. Kyiv has proposed swapping its interceptors for the more expensive air-defence missiles used by Gulf countries to down Iranian drones. Ukraine needs these missiles to fend off near-daily Russian missile attacks. The agreements highlight Ukraine's growing role as a leading producer of sophisticated, battlefield-proven drone interceptors. The country's expertise in downing Russian drones, which have been attacking Kyiv since the start of the full-scale invasion in 2022, is seen as a cost-effective solution for Gulf nations. For instance, Ukraine's interceptors cost around $2,000 each, compared to the $4 million cost of a Patriot missile. Zelenskyy's diplomatic tour aims to secure funding and technology in return for Middle East support. The US-Israeli war on Iran has depleted Patriot missile stocks, which concerns Ukraine as it needs these missiles to counter Russian ballistic missiles.
