Sydney Morning Herald - Iraq invasion spurs terrorism
Quick review of the misinformation:
No WMD's in Iraq plus a later cover-up when Bush claimed in 2003 that there were WMD's; the war has not paid for itself and will approach a total cost of 1 trillion dollars (Lawrence Lindsey, White House Economic Advisor, was fired for suggesting a total cost of $100-220 billion when the administration was putting out $50 billion for the total cost); and the claim that Saddam was harboring terrorists and therefore involved somehow in the 11 September attacks (Concluded the senior U.S. official: "Did Saddam tolerate terrorists? Yes. Was there any evidence Saddam was involved with 9/11? No.").
Here's another good revisionist timeline from 2004 - Center For American Progress - Why We Went In: Version 10.0
The only credible statement I read (I forget where) regarding the Iraq invasion is that the true purpose was a message to the other middle-eastern countries (e.g., Iran, Syria) that the U.S. will use the military for political purposes.
However, lines are now being drawn and China and Russia are backing Iran. Other countries are sitting to the side and the long-term ramifications of current U.S. policy do not look promising.
