What started the Iraq War of 2003-2011?
The Iraq War started when the United States invaded Iraq on
March 20, 2003. The United States invasion was predicated on the
belief that Iraq was in possession of "weapons of mass
destruction", in contravention of the Nuclear Non-Proliferation
Treaty and the Treaties following the Persian Gulf War of
1990-1991. However, no such weapons were ever discovered.
