When the real secret deals need to be made things are done here in Washington, modern-day Rome. Here is where everyone is summoned, politically and psychologically dissected, twisted and turned, to the Empire's will and designs.
It's a very complicated political dance now with a multitude of considerations and media/presentation nuances. The Americans need to portray in front of the co-opted Arab regimes as something other than Israel's benefactor and promoter, the superpower that enables the Israelis to do what they have for decades now. Hence all the talk about 'Palestinian State' and 'international conference' - tricks that have been used successfully before over many decades now to buy still more time for the Israelis to work their will, to pacify the Arab masses, and to help out the 'client regimes' with their own deceptions on their own people.
First of all, the Bush Admnistration is sprinkled at the senior levels with 'dually-loyal' Israeli types who themselves will twist and turn and prevent any real American initiatives to Israel's dislike. Sure, the Israelis may pretend not to favor certain things; but you can bet if the Americans are seriously proposing them the Israelis are one way or another supporting them.
Secondly, even if the White House should seriously contemplate something not to Israel's liking the combination of Israeli/Jewish lobby power, media influence, and Congressional backing, would make it impossible for such initiatives to proceed and they would be sure to be twisted along the way into forms the Israelis would actually desire, publicly or behind-the-scenes.
Only when the Arabs, possibly with some European support, develope real policies and real muscle of their own -- holding their meetings in their own part of the world and letting the Americans know they are no longer in charge of the affairs of the region -- will there be any hope. And that day, sadly, is not right around the corner; that's for sure.
