France and the Soviet Union assisted Iraq in the development of its nuclear program, but its primary facility was destroyed by Israel in 1981 in a surprise air strike.
In the decade following the 1991 Gulf War, the United Nations passed 16 Security Council resolutions calling for the complete elimination of Iraqi weapons of mass destruction.
Member states communicated their frustration over the years that Iraq was impeding the work of the UN Special Commission and failing to take seriously its disarmament obligations.
On 29 September 1998, the United States Congress passed the Iraq Liberation Act supporting the efforts of Iraqi opposition groups to remove Saddam Hussein from office.
The September 11, 2001 attacks brought to life Wolfowitz's and other "hawks'" advocacy for preemptive action; Iraq was widely agreed to be a likely subject of this new policy.
The Bush administration began a military buildup in the region, and after pushing hard gained passage of UN Security Council Resolution 1441.
Led by Hans Blix, Head of the United Nations Monitoring, Verification and Inspection Commission (UNMOVIC) and Mohamed ElBaradei Director General of the International Atomic Energy Agency (IAEA), the Resolution brought weapons inspectors back to Iraq in November 2002.
Inspectors began visiting sites where WMD production was suspected, but found no evidence of such activities, except for 18 undeclared empty 122 mm chemical rockets that were destroyed under UNMOVIC supervision.
On March 7, 2003 Hans Blix reported accelerated cooperation throughout the month of February but it was still not "immediate" and "unconditional" as called for by UN Security Council Resolution 1441.
Several close allies of the U.S. (e.g. Germany, Belgium and France) opposed a military intervention because they asserted it would increase rather than decrease the risk of terrorist attacks.
[8]On 17 March 2003 Bush stated in an address to the nation: Intelligence gathered by this and other governments leaves no doubt that the Iraq regime continues to possess and conceal some of the most lethal weapons ever devised.
At a news conference, he said: In a February 2003 joint declaration by Russia, Germany and France, Jacques Chirac remarked: The position of whether the invasion was legal under international law is unclear.
On March 17, 2003, Peter Goldsmith, Attorney General for England and Wales, set out his government's legal justification for an invasion of Iraq.
Most member governments of the United Nations Security Council made clear that in their view, after resolution 1441 there was still no authorization for the use of force and that the invasion was illegal under international law.
Yoram Dinstein equates this to police officers cornering a convicted violent felon and saying "put your hands on your head", but instead he pulls something small and black (whether a gun or not) out of his pocket.
To avoid initiating a crisis under the War Powers Resolution, the Bush administration sought explicit approval from the Congress to exercise force in Iraq.
On October 9, 2002, the Congress passed the Iraq Resolution which explicitly authorized the President to use the Armed Forces of the United States as he determines to be necessary and appropriate.
