In a significant shift of domestic oversight, the U.S. Senate voted 50-47 on Tuesday to advance a war-powers resolution. The measure aims to compel President Donald Trump to seek congressional authorization for continued hostilities or withdraw U.S. forces from conflict with Iran. This procedural breakthrough marks the seventh attempt to limit executive military authority since the conflict escalated in February. Despite the vote, the resolution faces a difficult path in the Republican-controlled House and a likely presidential veto. Simultaneously, President Trump disclosed that a military strike scheduled for Tuesday was aborted following diplomatic interventions from three Gulf states. While de-escalation efforts continue behind the scenes, U.S. maritime enforcement remains active. Officials confirmed the seizure of the sanctioned tanker 'Skywave' in the Indian Ocean, which was allegedly transporting more than a million barrels of Iranian crude. The administration appears to be maintaining a dual-track strategy of coercive economic pressure and diplomatic outreach. On the ground, intelligence assessments warn that Iran’s core military capabilities, specifically its underground facilities and missile stockpiles, remain largely intact. Additionally, new reports suggest Iranian threats to regional digital infrastructure, including subsea telecommunications cables in the Strait of Hormuz. Vice President JD Vance characterized the current diplomatic track as productive but emphasized that the U.S. military remains prepared to resume strikes if negotiations falter.
