However, the real catalytic event would seem to have been the recent capture by Israel of a covert shipload of weaponry bound for Gaza. Peeling away the various false flags from this operation, it appears that if Arafat was unaware of it, then he had no business to be. Put it another way: if he did know about the shipment then he seems to be acting in bad faith. And if he did not, and is so easily made to look a fool by his subordinates, then he is practically a spent force as a negotiating partner. You might call this Sharon's Fork; it is the twin prong on which he has long hoped to impale his old enemy. Sharon's motives are obvious. "Terrorism" or no terrorism, he thinks that the West Bank was given to the Zionist movement by no less a person than God himself. It is not, for him, a question of "security". (Nobody primarily interested in Jewish security would insist on building settlements in Gaza at a moment like this.) The United States, however, can hardly be expected to use the Old Testament or the Koran in attempting to arbitrate a territorial clash between two strident nationalisms.
