The Arabs revolting throughout the Middle East are doing so now, why? 1 reason. They've always thought the US would back the gov't to keep stability, and likely prevent an uprising. Until now. True or not, they THINK there is a Muslim in the White House who is sympathetic to their cause. The radicals, like the Muslim Brotherhood, in their minds think that now is the time to revolt, because the US president will do everything possible not to intervene because, as a Muslim, he sympathizes with them. I think that has a lot to do with it. Obama's speech in Cairo apologizing for America was almost like an official "go ahead" call to begin preparing for revolt. Thanks Mr. Obama. Your legacy may well read that you allowed the Middle East to implode.
