US policy shifted in 1998 when the United States Congress passed and President Bill Clinton signed the "Iraq Liberation Act" after Iraq terminated its cooperation with U.N. weapons inspectors the preceding August. The act made it official US policy to "support efforts to remove the regime headed by Saddam Hussein from power..." although it also made clear that "nothing in this Act shall be construed to authorize or otherwise speak to the use of United States Armed Forces." This legislation contrasted with the terms set out in United Nations Security Council Resolution 687, which made no mention of regime change.
