The US is pressuring Iraq to rein in Iran-backed militias, but doubts remain over the effectiveness of a proposed law to control the Popular Mobilization Forces (PMF). The PMF, an umbrella group for militias in Iraq, is part of Iran's 'Axis of Resistance' and has been targeted by the US due to its ties to Iran. The Trump administration's 'maximum pressure' campaign against Iran and the PMF's involvement in attacks on US interests in Iraq have increased the pressure on the Iraqi government to take action. However, critics argue that the current version of the proposed law does not ensure full control over the PMF or sever its ties to Iran.
