U.S.-Iran Tensions Persist as Trump Issues Ultimatum and Senate Debates War Powers

Tensions between Washington and Tehran remain critical as President Donald Trump issued a new ultimatum, stating the U.S. is willing to wait only "a few days" for a deal before authorizing "another big hit." White House officials, including Deputy Chief of Staff Stephen Miller, emphasized that no sanctions relief will be granted until a comprehensive agreement is reached, framing the current situation as a choice for Iran between total compliance or "massive military consequences." Simultaneously, the U.S. Senate has advanced a war powers resolution intended to restrict the President's ability to conduct unilateral military strikes, with four Republicans joining the Democratic majority in a rare show of congressional pushback. In the Persian Gulf, the Islamic Revolutionary Guard Corps (IRGC) has introduced a newly designated maritime zone in the Strait of Hormuz, requiring all entering vessels to seek authorization. While the IRGC reported coordinating the passage of 26 vessels over the last 24 hours, the new controls are seen as a strategic move to project Iranian authority over the critical energy corridor. This maritime posturing comes amid reports of a fragile ceasefire extension, which Turkish President Recep Tayyip Erdogan has characterized as a positive step for regional stability. Diplomatic back-channels are currently active, with Pakistan and Turkey leading mediation efforts. Pakistan’s Interior Minister Mohsin Naqvi recently met with IRGC commanders in Tehran to facilitate messages regarding Iran’s 14-point proposal. Internationally, Chinese President Xi Jinping and Russian President Vladimir Putin have called for a comprehensive ceasefire, stressing the urgency of de-escalation to prevent further disruptions to global trade and energy markets. Despite these diplomatic efforts, both the U.S. and Iran have maintained highly conditional public stances, leaving the prospect of a durable breakthrough uncertain.
