Iraq war "Illegal"?

Here’s one that’ll just get better http://boards.straightdope.com/sdmb/showthread.php?t=242238

It’s about the Senate Select Committee on Intelligence, which, afaict, is the only formal and official investigation into the Bush Admin’s use of the intelligence leading to the invasion of Iraq, specifically dealing with the issues surrounding:

the public statements and reports and testimony regarding Iraq by U.S. Government officials made between the Gulf War period and the commencement of Operation Iraqi Freedom were substantiated by intelligence information;
prewar intelligence assessments about postwar Iraq;
intelligence activities relating to Iraq conducted by the **Policy Counterterrorism Evaluation Group (PCTEG) ** and the Office of Special Plans within the Office of the Under Secretary of Defense for Policy;
and the use by the Intelligence Community of information provided by the Iraqi National Congress (INC).
An intial report from the SSCI is due out sometime between now and May. However, this report won’t address “how much intelligence was picked over to produce the desired result.” The SSCIS report that will address this is due out some “months” after the initial one, (whose draft is currently circulating in the Senate).
