But apathy to do that is to ignore Saddms history of past behavior. If we just let him keep WMD components and WMD personell is there really any sensible individual in the world who does not think that that Saddam would restart WMD producion once sanctions were lifted and UN inspectors gone. And remember we allready know WMD are more important to him than loss of oil revenues as he has given the UN 12 years of cause to maintain sanctions, so the consequences of lost oil revenue down the road if he restarted his WMD probram are inconsequential.
Basically what I'm saying is that, sadly , as was the case with Hitler, containment of Saddam would be ineffective without indefinite sanctions and indefinite inspections both of which are are unsaustainable over the long run due to the regions particularites. Those being in no particular order, the unstable (non) peace process in Israel/Palestine made worse by Saddam support of suicide bombers, yes of course Oil, general regional instability, the genaeral war on terror, muslim opinions about US opression of Iraqi civilians by sustained sanctions and a few others I dont have time to write about. So IMHO the USA decided the best thing possible was to oust saddam, and try to foster a democratic government in the area in an attempt to deal with those issues and not face an indefinite standoff with a Saddam family led Iraq.
So the real reasons are complex and specific to Iraq, WMD violation was the simplest one top communicate so it was brought to the forefront and it did provide an expedient basic legal justification. We have allready started finding WMD equpipment as outlined by Powell, captured Iraqi WMD scients under allied interrogation are said to be failing polygraphs left and right -they are lying, and we have yet to seach literally hundered of suspected WMD sites and lets not forget Iraq was able to hide large numbers of MIG25s in short order from allied surveilance in the recent war so I suspect that unkown WMD
sites will also pup up as well.
And for the UN devotees out there the UN declared that Iraq still possesed illegal WMD when the inspectors were forced out in 1998 and we know that some of these weapons materials were still ounacounted for as of late 2002/2003 in Iraqs final decleration. So, in fact , by UN accounting Iraq possed illegal WMD as late as the start of this year. Obviously this was a breach of 1441, but we all witnessed Frances defiance wrt to use of force in case of 1441 non compliance - so effectively the UN was neutralized in this case. And as so happened with Russian UNSC intransigence wrt to intervention in Kosovo, where NATO acted alone, an independant military alliance took action in Iraq.
