Israeli, if your argument is correct, then Ehud Barak would never even have suggested making peace with Syria. He publicly said he was prepared to give up the Golan Heights (with your precious water) and objected to a stretch of Lake Tiberias coast line. How could Barak be so irresponsible? Anyway, if Syria would try to block the streams from flowing into Israel (where else would the water then go? Would they build huge channels with water pumps that would pumr the water over the golan heights to the other side?) ISrael would bomb any little retaining wall.
