Time will tell all, and the facts will come out. For now, I know that Bush, Cheney, Powell, and Rumsfeld are not trigger-happy hawks. If they believe it's imperative that Hussein must go, then I figure they must have good reason for that belief. I also know that Hussein's obviously hiding something that he doesn't want the world to know about.
As for your reasoning as to why you think Hussein couldn't possibly be harboring al Qaeda terrorists, have you ever heard the line "the enemy of my enemy is my friend"? If Hussein could help anyone disable America, I believe he'd do it.
BTW, if the harboring of Al Quaeda types in Iraq is Dubya's concern why doesn't he demand that Iraq's turn them all over (as did for Afghanistan)? I'll tell you why. Al Queda is merely a pretext.
Do you really think a strong secularist, pro equal rights for women guy like Hussein is part of Bin Laden's fundamentalist Islamic movement? I have seen no evidence of this, certainly not even to put the lives of American women and men in peril.
Since you are so trusting of Bush and Cheney (though apparently not Powell), what do you expect to happen if and when we "win?" Are you expecting to break from historical precedent which indicate that "victory" would doom us to decades of social engineering, nation building, and futile efforts to make the Kurdish lamb lie down with the Shi'ite law. Are you prepared for all the unintended consequences of mucking around in the pest-hole of Iraq?
