On Friday in the US, President Donald Trump faces a legal obligation to withdraw American troops from the Iran conflict unless Congress intervenes to authorise their continued presence. Despite this requirement, the White House has asserted that the deadline is irrelevant, as US forces have not engaged in combat with Iran for weeks. This cessation of hostilities effectively provides Trump with an additional 60-day window to act if confrontations resume, pending Congressional approval of this interpretation.
Historically, while Congressional permission is necessary for military action, several past presidents have exploited legal loopholes to evade this requirement. The 1973 War Powers Resolution, designed to uphold Congressional authority over military engagements, inadvertently granted successive presidents a significant bypass.
Under this resolution, the President must inform Congress within 48 hours of deploying troops to combat, detailing the legal grounds, justifications, and an estimated duration of involvement. If Congress does not endorse the military action within 60 days following the report, the troops must be returned home. For Trump, this deadline falls on May 1. However, congressional support for the Iraq and Iran conflicts has waned, with no recent authorisations passed and efforts by Democratic lawmakers to constrain Trump’s military actions consistently repelled by Republicans.
Defence Secretary Pete Hegseth, during a Congressional session, conveyed the administration’s position that the current ceasefire halts the 60-day countdown. Trump extended this ceasefire just as it was due to end, although formal negotiations with Iran remain stalled. The White House has indicated that the hostilities established on February 28 have ceased.
This situation has drawn critical responses from figures such as Democrat Senator Tim Kaine, who questioned the constitutional validity of Trump’s stance, suggesting it contradicts existing laws. Nonetheless, this tactic is not unprecedented; former President Obama similarly contended that military operations in Libya adhered to the War Powers Resolution under the guise of “no active conflict.”
Trump may potentially challenge the resolution’s constitutionality in courts, much like Nixon attempted, or simply disregard the legal obligation to withdraw, relying on Republican support in Congress to deflect opposition. However, the growing unpopularity of the conflict—only 34% of Americans support it—combined with Trump’s declining approval ratings and pressure from upcoming midterm elections, may render Republican lawmakers more hesitant to support the president.
Senator Susan Collins, highlighting the urgency of the situation, emphasised that the set deadline should not be interpreted as merely advisory. As tensions persist, the political landscape surrounding American military engagement in Iran remains precarious.
