Nations don't have allies... they have interests. - Meir Kahane
Until the United States, the Israeli government, and world Jewry understand that the creation of a Palestinian state beside the State of Israel is a mutually exclusive condition, there will always be a "US-Israel" crisis. Just as there always has been. The Palestinians, to their credit, understand this. Indeed, it is their raison d'être; the establishment of a Palestinian State will likely lead to the long-term obviation of a Jewish state in the Middle East.
If the US was serious about supporting New Palestine they could cut off aid to Israel tomorrow. Unless Hashem breathes fire or the vaunted Messiah comes, Israel would wither on the vine like a biblical metaphor.
In this reader's opinion, American foreign policy vis à vis the Levant, has, for the better part of the last 70 years, involved a large degree of philanthropic naïveté directed at both parties. Israel gets just enough aid to sustain and defend against its enemies but a coterie of Arab states receives enough aid and support to sustain and perpetuate a low key war against Israel. The status quo is maintained: Holocaust guilt is assuaged, the Arabs more or less align with American interests (never mind 9-11 and all that hyperbolic ranting about "Jihad") and perhaps most importantly, the oil keeps flowing.
My concern is that since the Clinton administration, America has taken a fundamental shift from a center-right leaning outlook to one that is center-left. Bush Jr., was in my opinion, an outlier, narrowly elected and sustained by what was an outlier of an event: 9-11. With the perception of a common threat greatly diminished Americans would have appeared to have endorsed the Left's wet dream of a candidate... a bi-racial, ostensibly intelligent, academic, prodigy of the Ivy League who endorses and exemplifies the Leftist agenda of the late 60's and 70's.
Mr. Obama, who among other things, has exhibited gross incompetence in the area of force projection and geo-strategic thinking, is pretty much free now to put emplace his policies as drawn from the Leftist codex of post-modern revisionism... Cuba has been oppressed by US foreign policy, the Iranians are angry because of US colonialism and support for the Shah, a reset with Russia because Bush didn't know what he was doing (whoops, maybe Bush did know), etc, so on, quack quack, woof woof. If you want to see a nightmare team on foreign policy, look no further than Team Obama with Susan Rice at the controls. She's more powerful than the SECDEF. Good lord, what have we done? Actually, I didn't do it. I never voted for Mr. Obama. I can thank my liberal Jewish friends for that.
If I were the State of Israel, I'd be buddying up real hard to India, China, and possibly Russia. The strategic US/Israel relationship may be nearing its historic end.
