Sharon's disengagement plan is the act of a man who has gone to the salesroom and offered - let us say - a third of the price the goods must cost him if he really wants to buy. Yesterday the members of his own party tried to shout him down. They say: it's too much; make the man take 10%! Yet what if, rather than accept such a price, the man prefers to die? Or, more alarming for Israel, to kill?
