Re DASH2’s 3rd post: As for what is available on the “BBC,” could you be more specific? Otherwise, I will wind up watching old Monty Python skits.
As for your suggestion that Al Queda moved the WMD’s before the US could find them, that is idle speculation. And if they were moved, where did they go, and why were they not used in the last 10 years? And I am not sure that it was the CIA who reached an erroneous conclusion about WMD’s. I think it was their political bosses, e.g., Dick Cheney, who encouraged the CIA to interpret the raw intelligence to fit with his political schemes.
Exactly what positive effects the invasion had for the Iraqi people is hard to say. You point to their increased birth rate, but that might have happened anyway. And even if the overall impact of the invasion was positive (which I doubt), I do not think it was a wise use of my (or your, or other American taxpayers’) money, or the lives and limbs of American armed forces personnel.
