psychlist: "All in all, a very large portion of major political figures around the world believed that Iraq had WMD programs."
Not really. And it does not matter what anybody "believed." It matters what people had hard evidence for. And nobody had hard evidence that Hussein had significant amounts of WMD, and more importantly, that he had the will to use them.
Anybody remember the British reports that Hussein had capacity to drop biological agents from remote-controlled planes, or that he had armed missiles with WMD that could reach the UK within 45 minutes of launch? I do. All B.S., of course. It also turned out that the main report upon which Tony Blair had based his pro-war stance was plagiarized from a years-old grad student's masters thesis.
Let's also not forget that the so-called "Coalition of the Willing" consisted of a handful of first-world countries followed by a dozen or two countries who were basically bought off (as well as fast-tracked for favorable trade deals, etc.) so they'd add their names to the list. Several of those countries asked to have their names taken off the list, and were denied the right to do so by the U.S.
Pull the wool out of your own eyes. The Iraq war was a done deal long before anybody decided to claim Saddam Hussein had WMD. They didn't care if he had WMD, they just wanted to sell WMD as the reason to a gullible, fearful public.
