Burr's foreign policy views have been described as hawkish at times. In 2002, he voted for the Authorization for Use of Military Force Against Iraq Resolution, which authorized the U.S. invasion of Iraq. Burr supported President Bush's troop surge in Iraq in January 2007, saying that the effort to counter the insurgency would increase "security and stability" in Iraq. In February 2019, he voted for a measure disapproving of the withdrawal of U.S. military forces from Afghanistan and Syria. In February 2020, Burr voted against a measure restricting Trump from initiating military action against Iran without Congressional approval.
