I don't oppose all wars. What I am opposed to is a dumb war. A rash war. A war based not on reason but on passion, not on principle but on politics. Now let me be clear — I suffer no illusions about Saddam Hussein. He is a brutal man. A ruthless man. A man who butchers his own people to secure his own power. He has repeatedly defied UN resolutions, thwarted UN inspection teams, developed chemical and biological weapons, and coveted nuclear capacity. He's a bad guy. The world, and the Iraqi people, would be better off without him.
But I also know that Saddam poses no imminent and direct threat to the United States or to his neighbors, that the Iraqi economy is in shambles, that the Iraqi military a fraction of its former strength, and that in concert with the international community he can be contained until, in the way of all petty dictators, he falls away into the dustbin of history.
