The US House of Representatives has passed a resolution aimed at restricting President Donald Trump’s authority to conduct military operations against Iran. The ‘War Powers’ resolution, introduced by Democrats, was approved in Washington on Wednesday by a 215–208 vote, with four Republican members joining Democrats in support. The measure succeeded partly due to some Republicans’ absence and growing discontent within the party over Trump’s Iran policy.

Trump had pledged during his campaign not to start new wars and initially suggested that any conflict with Iran would end quickly. However, the source notes that resolving tensions through dialogue has become increasingly difficult. This is the first time such a resolution has passed the House after three previous failed attempts.

The decision is expected to influence similar efforts in the Republican-controlled Senate, though any measure would still require the president’s signature to become law. Analysts in Washington described the passage of the resolution from a chamber under partial Republican control as a rare setback for Trump.
