What criticism did the U.S. invasion of Iraq face?

The U.S. invasion of Iraq faced significant criticism for its justification and the ongoing violence that ensued after the initial military operation. Critics argued that the rationale for the invasion was largely based on unfounded claims regarding Iraq's possession of weapons of mass destruction and links to terrorist organizations, which were later discredited. Furthermore, the invasion led to a prolonged period of instability, violence, and insurgency in Iraq, resulting in high civilian casualties and significant humanitarian challenges. This ongoing violence prompted widespread debate about the consequences of the invasion and the adequacy of the U.S. government's planning for post-invasion governance and security in Iraq, ultimately leading to a reevaluation of U.S. foreign policy and military intervention strategies.
