Does it really matter whether there were wmd?
Firstly, the 'reason' of wmd wasn't the real reason we invaded Iraq.
Secondly, if it were the real reason it would not have mattered. If you believe in UN (which I don't) and are willing to give up sovereignty, then you must enforce its rules. Name one credible organization that did not believe that Iraq had wmd before the invasion?
So I ask, does it really matter whether there were wmd?
