As for the $87 Billion for post-war(?) Iraq...
there are questions from TrueMajority,

but how we got there and where we go now are not closed questions.

Regarding Misleading Intelligence... [culled from Inslee Iraq Forum]

*Whereas there has been Intelligence failure or a failure of intelligence.
*Whereas both big "I" and small "i" intelligence are important in declaring war and maintaining or discussing our position in the world.
*Whereas both are important in being successful on many issues as well as maintaining our nations position and credibility in the world.
*Whereas both Congress and the Intelligence community both depend on the credibility of information or it's providers to do their jobs.
*Whereas the public was asked to trust these representatives and agencies by the President himself.

Therefore be it resolved: that congress pass both House Resolutions as co-sponsored by Congressman Jay Inslee.

H.R. 2625 to establish an Independent Commission on Intelligence about Iraq.

H. Res. 307 to establish a select committee on Iraq intelligence.

(One HR involves the executive branch's collection, interpretation and presentation of intelligence as opposed to the latter's focus on the intelligence structure.)

FURTHER... important questions should be asked and answered.

*1. When did a policy of preemption take over?
*2. Were WMD a primary factor in congress’s abrogation of their "war powers"?
*3. Would not intelligence need to know the answer to question one or all intelligence would be interpreted in an ineffective light?
*4. Were actions taken, under the new policy, that would spur preemptive action by others?
*5. Was congress following at least this closely?
