At the time, I thought all the dire pronouncements about Saddam's nuke program were some pretty thin beer, with no solid publicly-released evidence to back them up, and the whole question about whether there was anything to his chemical or bio programs could have been resolved by a reconnaissance in force to a half-dozen of the most likely sites without buying into all the crap involved in a full-scale invasion and occupation unless the large-scale raid found something really important. I also thought (And still do, more than ever) that the touchingly-naive Rumsfeld-Bush-Cheney faith that everyone wanted to be Western democracies if only we removed their troublesome totalitarian rulers was ridiculously mistaken and could not end well.
As a Soldier, of course, I was perfectly willing to do my best to support whatever mission the Army got, whether I personally thought it was informed by sound strategy or not, because that's what Soldiers do. Of course Saddam and his two boys were definitely oppressive sadistic shitbags responsible for hundreds of thousands of deaths, and would have been responsible for hundreds of thousands more if left to their own devices, so taking them out was at least good kharma even if the reason and rationale for it was unfeasibly FUBAR beyond all coherent description.
A Soldier goes where his Army goes and fights its fights. Anyone in the profession of arms who doesn't want to go where it's happening for his side is in the wrong line of work.
