Iran hardens uranium position in talks Source
Iran’s Supreme Leader has directed that near-weapons-grade uranium remain inside the country, rejecting a central U.S. demand in talks aimed at ending the war. Washington and Israel want the stockpile shipped abroad, while Iranian officials see removal as leaving Tehran exposed to renewed strikes after any pause in fighting. Tehran is using physical custody of the material as a deterrent reserve and bargaining leverage, forcing Washington to choose among monitored dilution, continued military pressure, or a settlement that leaves Iran in control of the stockpile. Pakistan’s mediation gives both sides a channel for a technical compromise, but any formula that preserves Iranian custody leaves inspectors carrying the burden of proof. Iran’s leadership will likely use the current Pakistan-mediated peace talks to offer monitored dilution under inspection, preserving sovereign-control claims and keeping U.S.-Israeli strike planning active.
House presses Iran war-powers vote Source
The House is moving toward a Thursday vote to compel President Donald Trump to withdraw U.S. forces from the Iran war after the sixty-day War Powers deadline. Rising gasoline prices, disrupted Gulf shipping, and a fragile ceasefire have pulled constitutional authority into the same fight as energy stability and regional deterrence. Congress is using the ceasefire period to narrow the administration’s freedom to restart strikes while the White House argues that paused combat has already reset the legal clock. Military commanders still need authority to protect forces and shipping, but a successful resolution would make any renewed offensive action harder to justify without a public legal record. House leaders will likely use Thursday’s vote to force a clearer authorization record, limiting Trump’s ability to threaten renewed strikes unless the administration can tie military action to congressional approval.
Europe weighs China training report Source
The Kremlin dismissed a Reuters report that China’s military secretly trained about two hundred Russian soldiers last year, some of whom later fought in Ukraine. Reuters reviewed a Russian-Chinese agreement describing Russian training at facilities including Beijing and Nanjing, along with Chinese training at military sites in Russia. The reported exchanges would place Beijing inside Russia’s battlefield adaptation loop, weakening China’s claim to neutrality and giving Ukraine’s partners a firmer basis for diplomatic and sanctions pressure. Moscow’s denial protects Beijing’s mediation role while preserving military-learning channels that help Russian forces adapt against Western-backed tactics. European governments are expected to raise the issue at the May twenty-seventh to twenty-eighth Gymnich foreign ministers’ meeting, increasing pressure on Chinese military-linked exchanges.
