As for the timetable, though, I don't see any rush on the part of the Bush administration to enact or invoke such a thing.
Bush is a Christian who reads his Bible. I'm sure he knows that a "peace" is not possible among these people, although a temporary truce is (how temporary? Who knows. These can last up to years.)
Eventually, someone must come to one of two conclusions: either the Pales must be forced out of all the so-called "West Bank" and a large Berlin-style fence built; or a Pale state, regardless of nature, must be permitted to take root so that there can be no more excuses, then, when it attacks Israel and Israel crushes it, there will be SOME "international legitimacy" to the same result.
