I agree with your historical synopsis of how we got into our current predicament. But I don't agree with your conclusion. Have you forgotten that we were already spending billions on "containment" of Hussein for over ten years? The UN-sponsored "No Fly Zones" were being maintained at our expense. All the while, the French and Germans were screwing us with their "Oil for Food" fraud. And there is no doubt that the Iraqis were actively pursuing a nuclear bomb. So are Iran and North Korea.
Consider what's happening now in Iraq. All of the shitkickers doing the killing are Moslem fanatics, egged on by Moslem Imams. The claim that Iraq was "secular", meaning irreligious, and therefore not a threat is just not credible. Syria is in the same boat. I expect that the WMDs we haven't found since our Iraq invasion were just moved to Syria. If we want to win this war then we'll eventually have to confront and invade Syria, too.
I agree that we are in a war against Moslems. Further, I believe that its a war against ALL Moslems, whether we admit this or not. There are NO Moslem "moderates". That kind of thinking is PC bullshit, not borne out by the facts.
Lately, I've been trying to appreciate the irony of what 911 has wrought. The stupid ass half of this country that are dumbass Democrats are largely located in the high-density population centers. These are also the high-value targets that the mad Moslem murderers seek to destroy. At some point, these Moslem fanatics will be successful in carrying out another atrocity on the scale of the Twin Towers disaster. And the blame could be laid right at the feet of the potso son-of-a-bitches that did everything they could to hamstring and sandbag our ability to conduct our current conflict. And it'll serve 'em right!
I still think that we should have left Saddam alone or even helped him invade Iran, and Saudi Arabia.
