Let it not be said that Israel hasn't given up land for peace. It has in the past and is willing to do it again. Surprisingly, Israel's Olmert has offered Syria the Golan Heights in exchange for peace. He has asked that Syria cuts it ties with terrorist groups of Palestinians in Damascus. Israel had received the Golan Heights after the 1967 Six Day War where Syria was one of many Arab countries attacking Israel.
The problem is that the Golan Heights is now home to 20,000 Israelis. It is a beautiful area. Even the rabbis are against the offer and say it goes against Halacha. Army officials are saying that the topography is less important now than it was in 1967. Fighting has changed. What they might be worried about is guerilla warfare.
