Prediction: Obama Victory Will Bring 9/11-Type Celebrations to the 'Arab Street'

There are a lot of predictions out there regarding the election tomorrow. One of the safer predictions is that Obama's election will bring dancing, shooting in the air, and handing out of candy in the streets across the Arab world, similar to the celebration scenes following 9/11.
Of course, it is certainly possible that Arab radicals are merely under the delusion that somehow Obama represents a more hostile US attitude towards Israel. It won't be the first time that the Arab world miscalculates. But the question must be asked, why do radicals in the Arab world believe that Obama represents a change in policy towards Israel? Where did they get that impression? The likelihood that Obama will be "tested" in his commitment to Israel will certainly be forthcoming in the months ahead should he win this election... and ironically, he may win with the self-defeating support of a majority of American Jews.
