HISTORY

The Claim

The United States and its coalition partners invaded Iraq in 2003.

The Short Version

The historical record supports this claim. In March 2003, the United States launched the invasion of Iraq with allied partners, most notably the United Kingdom and Australia, and other states also contributed. Disputes about how broad or meaningful the "coalition" was do not change the basic fact that the invasion was U.S.-led but not purely unilateral.

Caveats

  • The term "coalition partners" can overstate breadth if read to imply that all listed coalition states sent combat forces; many offered only political or logistical support.
  • The military operation was overwhelmingly led by the United States, with the United Kingdom as the main additional combat contributor.
  • The invasion was internationally controversial and lacked explicit UN Security Council authorization, but that does not affect whether coalition partners participated.
