israel has proven, over and over, that it's only objective is to maintain the status quo(while further entrenching itself in palestinian territory), with its temporary deals that lead to nothing but more of same. a unilateral declaration of the palestinian state would be as well... because in doing so, and with its recognition by the united nations and the international community, they would end israel's game, which if left to its own, would continue indefinitely. with their state recognized by the u.n. as the territory outlined by the so-called "green line", negotiations with israel could proceed directly to resolving the border issues of a final status agreement. israel would be hard pressed to concede to the international recognition of the palestinian state, although not without a certain degree of bitter misgivings. but it would resolve the political dilemma faced by the israeli government over settler and right wing resistance to its withdrawal from the west bank. the strategic dilemma would remain, but that is inevitable.
