For Hamas, this conflict can only end one way: The Jews have to leave. Israel therefore has no alternative. It has to make it clear that if Hamas persists with that sort of thinking, the result will be that the Palestinians will have to leave. Or they can step bck from the precipice and come to terms. That means accepting publicly Isarel's right to exist as the sovereign State of the Jewish people. Very humiliating. But a much better alternative than Israel doing to them what they intend to do to Israel.
