US forces concluded their withdrawal from Iraq on Wednesday, fulfilling an agreement initially made during the Biden administration. This pullout marks the end of a long-term military presence following the 2003 invasion. Iraqi officials and security analysts are expressing concern that the departure will create a power vacuum, potentially empowering Iran-backed militias operating within the country. There are also fears that the withdrawal could allow Islamic State fighters to reorganize and regain strength in Iraq. The move raises questions about the future stability of Iraq and the ongoing fight against terrorism in the region. This decision effectively transfers security responsibilities fully to Iraqi forces.
