Which country did the United States of America go to war with after the attack of September 11?

Answer 1

Afghanistan and Iraq

Since the attacks of September 11, 2001, The United States of America has entered into war in both Afghanistan (October 7, 2001), and Iraq (March 19, 2003). The War in Afghanistan was in direct response to the September 11th attacks on the U.S. Conversely, while there was initial suspicion that the Iraqi Government of Saddam Hussein might have had some connection to the Al-Qaeda terrorists responsible for the 9/11 attacks, the declaration of the war in Iraq was ultimately based on separate issues pertaining the U.N. resolutions and sanctions pertaining to full disclosure and inspections for possible possession, or manufacturing of weapons of mass destruction, and/or the laboratories and components necessary to create such weapons.

As of September 11, 2001, The United States of America was under attack on its own soil, and since the attack came from terrorists with no known permanent base, or country of origin, the U.S. basically declared war on terrorism in general, and terrorist groups, cells and individuals world wide. Investigations and intelligence reports indicated that the Afghanistan based Al-Qaeda, the extremist Sunni Islamist militant group founded by, now deceased, Osama bin Laden, was behind the 9/11 attacks, and the Unites States began military operations to defeat Al-Queda, hunt down Osama bin Laden, and confront any country or group that would harbor terrorists, or in any way support or aid their activities.
