I disagree. The legal line is still there and it could be withdrawn to. Peace treaties would be a bit harder and there's ... nuts, how many needed? Gaza/Hamas, West Bank/ PLO, Jordan, Syria ... at least. But surrender? Nope. Once Israel was on land that almost the entire world agrees is hers, she can defend it with vigor. It's bad press when Israelis kill Palestinians on their own land. Much easier when they kill terrorists who are on internationally agreed Israeli land.
