All right, how about this reason not to invade Iraq: It's none of our damned business. If the US is an empire, I'd feel much better if we came out and admitted it. Until then, we are most certainly NOT the high moral ground, or the judge of the world. Hell, we're the only industrialized Western nation still killing its own citizens. Like it or not, we're the psycho hicks of the world, and the less we meddle in other peoples' business, the better. And that includes to the extent of letting a charismatic despot kill his own people. When they get sick of it, they'll kick his ass something good, just like has ALWAYS HAPPENED, WITHOUT FAIL, when the government became too much, throughout history. The only reason to really intervene is that we're greedy powermongers, using this as a lever to increase our chokehold on the one area of the world that still openly bares its teeth to US imperialism. And our government's at least as despotic as Saddam, if recent foreign policy trends are any indicator, it's just that our government does it to everyone else's people.
Or, if you want to go the pro-US route, because our greedy powermongering and meddling where we should not is already losing us our allies. Europe, once essentially a puppet of the US, is really starting to get uncomfortable with us. Most nations already are starting to get unpleaasant with the US, like the drunk at a party that keeps picking fights, feeling up the women, and making loud declarations. We're toeing the line where they throw us out, except that in international politics, the dude doesn't go throw up in the nearest dumpster, the nation has its leaders killed, its morale crushed, and its population effectively enslaved by the invaders. I'm sick of being dicked with by government as it is, I don't wanna be a colony. The colony, as always in history, really gets it up the collective arse, and it's not fun.
