This resolution would require the President to stop any military operations involving U.S. troops against Iran unless Congress has specifically voted to approve that action—either through an official declaration of war or a separate law authorizing force against Iran. Right now, presidents sometimes order military action without a fresh vote from Congress, relying on other legal justifications; this measure says that when it comes to Iran specifically, that shouldn't happen without lawmakers weighing in first. In practice, this affects how and when U.S. military forces can be used against Iran, shifting more of that decision-making power to Congress rather than leaving it solely with the President.
