"Show me just what Mohammed brought that was new, and there you will find things only evil and inhuman, such as his command to spread by the sword the faith he preached." - Manuel II Palelologus
IMHO what has now happened is much bigger than that, even according to their own pronouncements, i.e. Iraq being the central front.
If AQ has been REJECTED, in this case violently, by even the less secular Sunni of Iraq, what message does that send to the rest of the Sunni world about AQ? They may be saying, "The AQ attack on the US was ok, but that doesn't mean I want AQ controlling how I live". Look at what the Sunni in Iraq think of them."
If that is happening then history may record "The Surge" as the turning point in NOT ONLY IRAQ BUT THE WAR AGAINST MUSLIM EXTREMISM. And if that is true, then George Bush will be seen by history as a very important and successful President; something the Dems fear even more than a Muslim extremist victory.
