I'm afraid that Buck O's reply to your post about Obama's low approval rating in Israel - "Most American "Jews" are secularists who don't care much about Israel." - is right on the money.
Up to about a generation ago, American Jews DID solidly identify with and support Israel.
That they don't is a tribute to how successfully the Left has brainwashed them and unmoored them from their spiritual roots.
It's all the MORE a measure of the Left's success in this realm that the Left OPENLY flaunts its anti-Jewish sentiments - we saw this on display IN PROFUSION at the Occupy Wall Street gatherings - and yet the majority of Jews STILL join arms with these folks.
