Senate Moves to Limit War Powers Amid Fragile U.S.-Iran Ceasefire

In a significant challenge to executive authority, the U.S. Senate voted 50–47 on May 19 to advance a procedural motion on a war-powers resolution. Sponsored by Senator Tim Kaine, the measure seeks to invoke the 1973 War Powers Resolution, which limits unilateral military action to 60 days without congressional approval. The legislative move comes approximately 80 days after U.S. and Israeli forces began strikes against Iranian targets, signaling growing domestic pressure to define the legal boundaries of the ongoing conflict. On the diplomatic front, President Trump announced he recently paused a scheduled military strike against Iran following the receipt of a peace proposal from Tehran. While the President noted there is now a 'very good chance' for a new nuclear deal, he emphasized that U.S. forces remain positioned for a 'full, large-scale assault' if negotiations fail. Diplomatic communications are reportedly being facilitated through Pakistan, with Iranian Foreign Ministry spokesperson Esmaeil Baghaei confirming that Tehran’s positions have been conveyed to Washington through Pakistani intermediaries. Despite these diplomatic openings, the security situation remains volatile. Reports of drone launches from Iraq targeting Gulf nations, including Saudi Arabia and Kuwait, have heightened regional anxiety, though Iran has officially rejected allegations of involvement. Inside Iran, officials have warned that any renewed 'U.S. aggression' will be met with a stronger response. This rhetoric coincides with unconfirmed reports from Iranian media suggesting that the U.S. may be considering oil sanction waivers as a bargaining chip in the current high-stakes negotiations.
