Justice requires that the first step towards a settlement must be an Israeli withdrawal from all the territories occupied in June, 1967.

Yes BUT.

I believe given the rhetoric from countries like Iran and Hezbollah, such a give-back would result in future losses of even more land. Eventually sovereign Israel would be physically squeezed into a pocket like Gaza is now.

Israel requires buffer zones that they must maintain by force.

Conclusion (mine):

I'm not a Zionist. But Israel is needed, by Israel.

It is what it is, said every obnoxious authority figure ever.
