Senate Moves to Limit War Powers Amid U.S.-Iran Diplomatic Standoff

In a significant shift in domestic policy, the U.S. Senate advanced a war powers resolution on May 21, 2026, aimed at curbing President Donald Trump’s ability to conduct further military strikes against Iran. The measure gained traction with the support of four Republicans and the majority of the Democratic caucus, signaling a growing rift between the White House and Congress over the trajectory of the ongoing conflict. Despite this legislative pushback, President Trump maintained that the U.S. military remains poised for action, though he noted he is 'in no hurry' to reach a terminal peace agreement. On the diplomatic front, Pakistan continues to serve as a vital intermediary, facilitating indirect communication between Washington and Tehran. Iranian officials confirmed they submitted a new proposal this week, though reports indicate the terms largely mirror previous demands, including the withdrawal of U.S. forces and the lifting of economic sanctions. Meanwhile, Iran has moved to institutionalize its leverage over the Strait of Hormuz by creating the 'Persian Gulf Strait Authority,' a move intended to provide a legal framework for its presence in the critical maritime chokepoint. The Islamic Revolutionary Guard Corps (IRGC) has escalated its rhetoric, warning that any resumption of U.S. or Israeli strikes could trigger 'asymmetric' retaliation reaching beyond the Middle East. While no new kinetic strikes were reported in the last 24 hours, the military posture remains in a high-tension holding pattern. International observers also remain focused on Iran's nuclear program following reports of new progress, though no specific technical milestones have been officially confirmed by international monitors during this period.
