Regime change in Iraq has been official US policy since 1998. The Iraq Liberation Act of 1998, signed into law by President Clinton, states:

"It should be the policy of the United States to support efforts to remove the regime headed by Saddam Hussein from power in Iraq and to promote the emergence of a democratic government to replace that regime."
