That's obvious. The uninformed are easy to fool with propaganda.
See? Already you have been fooled. Even Putin said he told Bush Saddam had WMD's. And we did in fact find a large stockpile that Saddam specifically said was destroyed. But it is right that we didn't find very much. But there are reasons for that.
First Saddam was telling his allies that he had WMD's so he didn't look week in their eyes. Then he did in fact have WMD labs up and running. Many WMD's need to be produced right before use because they are more powerful that way.
Who the hell said we attacked to liberate? I believe you are talking about the post war, when we stayed afterwards to help them recover.
Of course terrorism didn't exist there, but terrorists did. Terrorists do not attack their benefactor. Some of the anecdotal evidence was that Al-Qaeda was running out of money at one point, then after their meeting with Iraq, they were suddenly awash in it. Coincidence? I doubt it.
But there was no government there after the war. By staying and helping, we are doing humanitarian work. As well as helping keep them from being taken over by Iran. Besides, if we had left afterwards, you would be complaining about that. That we didn't stay around and help them. You know its true.
So your belief is that we should just stick our heads into the sand, and ignore the people who have been calling for our destruction for decades? Yeah, that works.
