The United States Senate has blocked a War Powers resolution that would have constrained President Donald Trump‘s authority to unilaterally wage war against Iran, as domestic opposition to the conflict deepens and the administration faces mounting questions about its strategic objectives.
The resolution failed by a vote of 53-47 — the same margin recorded on March 4 — with senators dividing almost entirely along party lines. The sole Republican to break ranks was Senator Rand Paul, who voted in favour of the resolution. Democrat Senator Jon Fetterman crossed the aisle in the opposite direction, voting against it.
The war, launched with strikes on February 28 in coordination with Israel, has now claimed the lives of at least 13 US military personnel. The Pentagon has deployed additional troops to the region, and Secretary of Defense Pete Hegseth has appealed to Congress for $200 billion to fund the campaign. Senator Lindsey Graham has pledged to advance a reconciliation bill that would allow the Senate to pass war funding with a simple majority of 51 votes, bypassing the 60-vote threshold required to overcome a filibuster.
Despite those legislative manoeuvres, cracks are appearing within Republican ranks. Representative Lauren Boebert told reporters she was ‘tired of the Industrial War Complex getting our hard-earned tax dollars,’ while Representative Nancy Mace stated she would not support the deployment of ground troops in Iran following a House Armed Services Committee briefing. Conservative commentators Tucker Carlson and Megyn Kelly have also emerged as vocal critics of the conflict.
Democrats in the Senate have promised to hold weekly votes to keep the War Powers issue alive. Their counterparts in the House possess sufficient votes to pass their own resolution, but House leadership has retreated from scheduling a floor vote.
Public sentiment is turning sharply against the war. A Reuters/Ipsos poll released this week found 61 percent of Americans disapprove of the conflict, against just 35 percent in favour. A separate survey by the Associated Press-NORC Center for Public Affairs Research found that 59 percent of Americans believe US military action in Iran has been excessive. Trump’s overall approval rating has slumped to 36 percent — the lowest recorded since he assumed office.
The partisan divide remains stark, however. An NBC poll found that 90 percent of self-identified MAGA voters support the war. The AP-NORC survey showed roughly half of Republicans consider the military campaign to have been calibrated appropriately, while a quarter believe it has gone too far.
The administration has pointed to the degradation of Iran’s military capabilities and the assassination of senior Iranian officials as evidence of progress. Director of National Intelligence Tulsi Gabbard offered a more measured assessment, stating that ‘the regime remains intact but largely degraded.’ Trump has continued to assert that talks with Iranian officials are ongoing, though Tehran has publicly rejected his ceasefire proposal.
Observers and analysts have warned that the conflict appears to be entering a phase of attrition — a dynamic they argue strategically favours Iran. The administration has yet to articulate a unifying endgame for the campaign, leaving lawmakers and the public without a clear benchmark for success or conclusion.
The combination of rising casualties, a $200 billion funding request, a stalled diplomatic track, and deepening public opposition is intensifying pressure on the White House. Whether the weekly Senate votes Democrats have promised will shift the political calculus — or simply harden existing divisions — remains to be seen.
