Should the US attack Iraq?

I was watching a tv special the other day and it was about ww2 and how all the people in America were arguing about going to war with Germany, well guess what the majority like today didn't want to get into it for whatever reason possible (this was before all of the Jews were being slaughtered) so we did stay out and a couple years later we did get drawn into it (after millions have died). we could have stopped all those peoples suffering and what do you think Hussein is nothing but another crazy ass fanatic like Hitler so I say we are gonna be thrown in it sooner or later it is inevitable, lets just do it before Suddam has the chance to hurt some innocents and make another generation deal with some more horrible tragedys...
