Once Israel wins the war, does that automatically mean peace. They have won wars before. In 1949, 1956, 1967, 1973, and 1982. Peace has not been the aftermath. She may have won the "war" but the battle is still engaged...
Because the US and the UN persuaded Israel to give up most of what was won. This time, there'll be nothing but scorched earth left of these critters. Then Israel can get on with the business of peace - of course with 17 nukes pointed at every Arab city. And personally, I hope the firing buttons are ticklish enough to go off if a fly lands on one.
