The US military has officially announced the completion of its withdrawal of troops from Iraq, marking the end of a 12-year mission against ISIS and a broader military presence that lasted 23 years. This significant shift has raised concerns about a potential power vacuum in the region, as Iran-backed militias may exploit the situation. Celebrations in Iraq coincide with fears of rising instability, as the nation braced itself for the implications of the American exit. The withdrawal comes as Iraq grapples with security challenges and tensions with militant groups, leaving many to question the future dynamics in the region.
