Instead of saying that the American Jewish Establishment is "terrified by Palestinians," it might be more accurate to say they are terrified by the possibility that the wretched Palestinians might gain support at the expense of Israel. And of course they're rational to be terrified, because the Palestinians are gaining support, at Israel's expense. Even though many Palestinian leaders are jailed by Israel.
Actually, the Palestinian cause is already supported worldwide, not just in the Arab world, judging by votes in the UN.
You mentioned David Frum, who used to be a somewhat important neoconservative. His claim to fame was inventing the phrase "axis of evil", meaning three countries (Iran, Iraq and North Korea)
N Korea had nothing to do with either of the other two, and Iran and Iraq had recent waged a very bloody war. Yet Frum's phrase was incorporated in G W Bush's speeches.
I see From has recently become disillusioned with Republicans and conservatives, and idiots.
But I repeat myself.
