I guess I should have been clearer. My suggestion was suppose to be that if the USA leaves Iraq, there will be no reason for Al-Qaeda to be ACTIVE there (ie bombing, killing, etc...) and so therefore, i suspect they will not be seen there.
So if the US left Afghanistan, there would be no reason for Al Qaeda to be active there either, right? We aren't after Al Qaeda because of their activity in the Middle East, we're after them because of their activity OUTSIDE the Middle East. Sadly, if they would have kept their killings and bombings over there, the West would probably have barely noticed.
Will they use Iraq as a "base" in order to regroup...perhaps, but Al-Qaeda members can likely be found doing the same in UAE, Egypt, and Pakistan...will McCain et al take American Soldiers into these countries as well?
Once again, our reason for being in Iraq isn't just that Al Qaeda is there. It's one of several reasons that include maintaining stability in the young democracy, helping rebuild the country, fighting insurgents, etc. I think there would only be a good reason to go into Pakistan, Egypt, and UAE if Al Qaeda were based there and those governments refused to do anything about it. As of now, the Taliban and Al Qaeda are in Pakistan, but the Pakistani military is working to keep them out and hunt them down. Egypt is not particularly sympathetic to Al Qaeda (though many Egyptians are, I'm referring to the government) and has imprisoned their members both in the present and the past (Zawahiri). Al Qaeda members have made several attacks in Egypt and, while their doctrine might gain some sympathy, the movement itself is generally disregarded. Despite the ranks of Al Qaeda having many Saudis, bin Ladin is a sworn enemy of the Saudi government (though I would like to see a much firmer hand taken with them).
