Answer: The mentioned states had terrorist cells within their borders connected with the attack on the United States.
Step-by-step explanation:
The terrorist attack on the United States meant a global declaration of war on terrorism by the government. The attack on the United States was carried out by the terrorist organization Al Qaeda, in which a huge number of innocent people were killed. That terrorist organization was mostly stationed in Afghanistan but had its cells in other countries as well. One of these significant cells was also located in Iraq. That was the reason for the united states for military interventions in those countries. However, the military intervention in Iraq was primarily aimed at overthrowing the rule of terror in the country by Saddam Hussein.
