The "Post-2003 Conflict" refers to the ongoing violence and instability in Iraq following the U.S.-led invasion that began in March 2003. The invasion aimed to remove Saddam Hussein from power, but it led to a power vacuum and the rise of various insurgent groups, sectarian violence, and civil unrest. In the years following the invasion, Iraq faced challenges such as the emergence of ISIS, political corruption, and ethnic tensions. Efforts to stabilize the country have included military interventions, political reforms, and international assistance, but the situation remains complex and volatile.
