Way back in March, the Washington Post reported, "Al-Qaeda in Iraq is the United States' most formidable enemy in that country. But unlike Osama bin Laden's al-Qaeda organization in Pakistan, U.S. intelligence officials and outside experts believe, the Iraqi branch poses little danger to the security of the U.S. homeland."

And yet, over and over again yesterday, Bush insisted that the vioence from Iraq's civil war would follow us home.

"If we were to fail, they'd come and get us. … If we let up, we'll be attacked. … It's better to fight them there than here."

Slate's Fred Kaplan explains, again, why this is the wrong argument.

First, the vast majority of the insurgents have nothing to do with al-Qaida or its ideology. They're combatants in a sectarian conflict for power in Iraq, and they have neither the means nor the desire to threaten North America.

Second, to the extent that the true global terrorists could attack us at home, they could do so whether or not U.S. troops stay or win in Iraq. The one issue has nothing to do with the other.

Third, what kind of thing is this to say in front of the allies? If our main goal in bombing, strafing, and stomping through Iraq is to make sure we don't have to do so on our own territory, will any needy nation ever again seek our aid and cover? Or will they seek out a less blatantly selfish protector?
