Paul has been among the most prominent voices warning against military intervention. When Trump last month called off retaliatory military strikes against Iran after an Iranian military official downed a U.S. drone over international waters, Paul went on the president's favorite television network to offer unqualified praise. "It really takes a statesman to show restraint amidst a chorus of voices for war," Paul told Fox News' Martha MacCallum.He also took a jab at the administration's policy, arguing that Iranians view the punishing sanctions imposed by the Trump administration as "an act of war."
Earlier this year, Paul pressed [Secretary of State Mike] Pompeo on whether the administration believes it has the authority to battle the Iranian regime under a 2001 law that allowed the U.S. to pursue the fight against al Qaeda and affiliated terrorist groups in Afghanistan and beyond.
When Pompeo tried to sidestep the question, Paul warned the administration not to pursue such a conflict, at least not without Congress' imprimatur.
"You do not have the permission of Congress to go to war with Iran," Paul told Pompeo during the April hearing on Capitol Hill. "Only Congress can declare war."
