US Senate to vote on Trump’s Iran war as conflict escalates

New Delhi (UNI): The United States Senate is set to vote on Wednesday, March 4, on a war powers resolution seeking to curb President Donald Trump’s authority to continue military operations against Iran, marking a crucial constitutional moment as the conflict in West Asia enters its fifth day with no clear US exit strategy.
The resolution was spearheaded by Senator Tim Kaine would require explicit congressional authorisation before further US military action against Iran.
Then the resolution is expected to come up for a vote in the United States House of Representatives later this week. However, both face steep odds in the Republican-controlled Congress and would almost certainly be vetoed by President Trump if passed.
The votes represent a consequential test of Congress’s war-making authority after Trump ordered surprise strikes on Iranian targets on February 28 without prior congressional approval. Lawmakers now confront the political and constitutional implications of a rapidly expanding conflict that has already drawn in regional actors and threatens global energy supplies.
“Wars without clear objectives do not remain small. They get bigger, bloodier, longer and more expensive,” Senate Democratic Leader Chuck Schumer said at a news conference Tuesday. “This is not a necessary war. It’s a war of choice.”
The conflict began with coordinated US- Israeli strikes on Iranian military and strategic facilities. Iran responded with missile and drone attacks targeting Israel and US-allied Gulf states, escalating fears of a broader regional war.
On Monday, Trump said Washington would look to “destroy Tehran’s missile capabilities, annihilate its navy, stop it from developing nuclear weapons, and prevent Iran from supporting terrorist proxy groups abroad”.
“Whatever it takes,” Trump said. “Right from the beginning, we projected four to five weeks, but we have capability to go far longer than that . . . We haven’t even started hitting them hard.”
Since launching the offensive, the Trump administration has intensified outreach to lawmakers, dispatching top officials to Capitol Hill in an effort to reassure sceptical members that the operation remains limited in scope.
Secretary of State Marco Rubio told reporters Tuesday, “We are not going to put American troops in harm’s way,” insisting the administration had complied fully with legal notification requirements.
While Trump has said he hopes to conclude the bombing campaign within weeks, he has not ruled out deploying U.S. ground forces if necessary. His stated objectives have evolved — from suggestions of regime change to halting Iran’s nuclear ambitions and degrading its naval and missile capabilities.
In a letter to Senate President Pro Tempore Chuck Grassley, Trump described Iran as “one of the largest, if not the largest, state-sponsors of terrorism in the world” and warned that its missile arsenal posed a direct threat to U.S. forces and commercial shipping. He maintained that no American ground troops had been committed to the operation.
Members of Congress received a classified briefing Tuesday from Rubio, Defence Secretary Pete Hegseth and other senior officials. The session, however, appeared to deepen divisions rather than resolve doubts.
“This is as serious as it gets,” Senator Chris Murphy said afterwards, warning that officials acknowledged more American casualties were likely. “We have to have a debate in the United States Senate on the authorisation of military force.”
Senator Richard Blumenthal said he was “more fearful than ever” that U.S. troops could eventually be deployed on the ground, while Senator Brian Schatz said lawmakers remained “as confused as the American people” about the administration’s long-term strategy.
On the Republican side, most senators were expected to oppose the resolution, though some voiced caution about committing ground troops. Senator Bill Cassidy said he did not believe Americans wanted boots on the ground in Iran but acknowledged that officials had not entirely ruled out the possibility.
Senator Markwayne Mullin defended the strikes, saying the U.S. was targeting a regime that had long sought to harm American interests. Meanwhile, Senator Lindsey Graham argued the widening conflict could present an opportunity for Arab and European allies to join efforts against Iran and affiliated militant groups.
At the heart of the dispute lies the War Powers Act, which requires the president to notify Congress within 48 hours of initiating hostilities and withdraw forces within 90 days absent authorisation.
Rubio contended that the administration had complied with the law and argued that successive administrations, Republican and Democratic alike , have questioned the constitutionality of the War Powers Act’s constraints on executive authority.
House Speaker Mike Johnson said the administration had briefed the bipartisan “Gang of Eight” prior to the strikes and acted within its authority.
However, House Democratic Leader Hakeem Jeffries signalled strong Democratic backing for the resolution, while Representative Gregory Meeks urged the administration to publicly articulate its strategy. “Our young men and women’s lives are on the line,” he said emotionally after the briefing. The conflict will shape the upcoming midterm elections.
