Actually I don't think Bush did it for humanitarian reasons either (but I think you know that )...I personally think that it needed to be done for that reason...but I imagine his reasoning was more he needed a target in the fight against terrorism and they were the most convenient.
But that's what really grinds my balls, if he had said 'Ok guys this Saddaam is a real bad guy and what we are going to do is free his people and as an aside we are going to use the war as an economic kick start and obviously benefit from the oil and reconstruction contracts' then I would have said, 'yeah ok, it's a bit rich you offering to free a people when you are restricting the freedoms of Americans but let's do it anyway so they get the measure of freedom that we have'
That would have been honest, and I am sure that despite being a fucktard that Bush is genuinely agrieved at the evil things that Saddam did to his people. Thing is that if he had said that then he would have had to have gone into other countries that are worse - Zimbabwe, Saudi etc
The thing that really worries me about this is twofold - firstly I am not sure that we have effectively combatted terrorism. Look at Israel, by blowing up houses and by using massive force the Israelis have succeeded in amplifying the justification for terrorism in the minds of most Palestinians. Terrorism only works when it has the support of a indigenous population against the target and Israeli actions have alienated the ordinary moderate Palestinians to the point that more extremists and more bombers to be are created.
Secondly look at the precident - any country can do whatever the hell it likes because international law and the credence of the UN doesn't matter any more.
If it was about WMD's then Hanz Blix would have been given more resources and time. He was bumrushed for political expediency which is terrible.
