"Its because the left, much like here in this country, cannot be trusted with national security."
True. I completely distrust the Left, both here and in Israel. However, I have to add that the Israeli Right seems insane to me. (I am an American Jew.)
What's so insane about not wanting to feed pieces of Israel to the crocodile? The right wants to defend every piece of Israeli soil (hard fought and won in previous wars). Sharon and the left want to disengage from Judea itself.
