Actually there is already a regional war under weigh. It is a Sunni Shia more or less Civil War within Islam itself. Map borders do not confine it. The Sunni Kenyan us trying to take down the Iranian ally and surround Shia Iran and infidel Israel in one operation. If he can surround Israel with a Sunni rampart he probably thinks wiping off the Jews will become easier. If he succeeds I expect he will turn on domestic American Jews after.
