Anyone who wants to know how it ends just needs to read Revelation.
The war will be fought until one side wins and the other side loses. When I mean win—they must consume and destroy the other side until there is no one left to wage war. It is a cold and terrible pronouncement but—I fear— True. No treaty will do—only a funeral. The Arabs must be pushed into the sea and killed—everyone, or the same will happen to the Jews. Not one will be left alive. The conflict will end only in a Holocaust for one side or the other. If I was an Israeli I would move to the USA as quickly as possible. I believe the Arabs have the edge—their religious fanaticism will win the day for them if it takes another 100 years.
