Edward Luttwak notes an essential point: Greater Israel is sustained more by Christianist Americans than anxious American Jews:
The cleanest analytical way of understanding the American-Israeli relationship is to say that the post-1945 career of the United States as a world-meddling, imperialist power has forced Americans to be very foreign-oriented. Many American families have had their sons killed overseas, and many other Americans have become foreign-oriented for many reasons. Among them there is a group of Christians who read the Bible, who believe in the Bible to some degree as a document that registers God's will. For them, Israel is the proof of the truth of the Bible. Hence, the notion that the United States should be supporting rather than opposing Israel has now become expected, which was absolutely not true in 1948 when the United States did every possible thing to prevent the existence of Israel by systematically intercepting arms flows to the Jews.
Therefore, if we in the Z.O.G. didn't really run everything, and there was no Zionist influence, then this solid mass of foreign-aware Americans, who also happen to be Bible-believers–we're talking 50 million people–to them, the only foreign policy that counts is America's support for Israel. Period.
Spot-on, although the cheerleading or quiet encouragement of Greater Israel from the American Jewish Establishment doesn't help. All of which explains the hilarious/tragic spectacle of the US government furiously attempting to prevent the UN from recognizing the two-state solution that the United States has supported for as long as one can recall. You don't know whether to laugh or cry; but we all know where all this ends – capitulation to the most extreme elements of the American and Israeli right.
One of Mitt Romney's dumber lines (and there are plenty to choose from) is that Obama has no foreign policy. This is only true, it seems to me, on Israel. There the president has no real leeway or leverage to achieve any ends at all, and therefore no foreign policy. The foreign policy is set by US public opinion, and sustained by elite media granstanding for the Christianist imperial and apocalyptic project in the Middle East.
