The Americans threaten Israel with total isolation if they do not make place for a Palestinean state. A totally rational decision will see a totally irrational world-wide response. The world will surely try, once Israel brings the "peace process" to a halt. However, the "problem" is that without Israel the world has no right to existence. Therefore, they will try but succeed only because the world economy will crash.
The Israeli left will be blamed for causing this state of affairs. However, the Israeli left is merely a means. They acted as a shield, until the proper time. Sensitive to the world opinion, they are not the reason for this world opinion. Forget and forgive.
