Listen without illusions?

Friends have asked me what what I thought of Obama's speech in Cairo. I sent them this article by Slavoj Zizek

"Days before the election, Noam Chomsky told progressives that they should vote for Obama, but without illusions. I fully share Chomsky’s doubts about the real consequences of Obama’s victory: From a pragmatic-realistic perspective, it is quite possible that Obama will just do some minor face-lifting improvements, turning out to be “Bush with a human face.” He will pursue the same basic politics in a more attractive mode and thus effectively even strengthen U.S. hegemony, which has been severely damaged by the catastrophe of the Bush years."
