The purpose of the Free Iraq from Iran Act is to establish a comprehensive strategy for the United States to support Iraq in freeing itself from the influence of Iran and its affiliated militias. The act aims to promote democracy, rule of law, and human rights in Iraq, aligning U.S. foreign policy with the aspirations of the Iraqi people. Key provisions of the act include the requirement for U.S. government agencies to develop a strategy within 180 days that outlines efforts to dismantle Iranian-backed militias in Iraq, such as the Popular Mobilization Forces.
