Right on Reliquary;
When Israel's modern boundaries were established, they included all of the West Bank and much land on the east bank of the Jordan. Due to the incessant complaints by the Hashemite tribes, Israel ceded much of it's land in a "land for peace" scheme of the time. What did they get for it, besides 2-3 major wars and continued terrorist activity ?
Below is a map of the original mandate for post war Israel. It included what is now Jordan etc.... The Israeli's traded land for promises of "peace".
Note the map of today's Israel... Including the West Bank, Israel has give up more than half of what it was originally entitled to. You can note the latest notch.. out of the lower left corner of Israel..which is Gaza,,,,,,,,,,,,,,,,,,,,,,,,,
You are right..time to pull out completely and let those tribes go ahead and cut each other to pieces, it's obvious they are reluctant to part with the 7th century..
