Gen. Petraeus and countless others who agree with him are not 'blaming the Jews' for America's failure to build a Middle East policy that is in its national interest, they are saying that it is America's support of Israel's behavior that has negative consequences for our diplomacy in Islamic countries. There is a big difference between these statements. I suspect that you will not see it. Anyone who thinks that Israel's degrading treatment of its Arab citizens and neighbors has no effect on the geopolitical opinions of Muslims vis a vis Israel's only ally, the USA, should think again.
