The NYT piece is fantasy with some scraps of food for thought lurking like tiny little jewels in a crock of shite. Here's the nub:

"But perhaps the progressive Israeli government might yet succeed if a U.N.-sanctioned, U.S.-led force — you might almost call it a mandate — agreed to deploy peacekeeping forces to guarantee Jewish rights and security."

A truly progressive Israel would immediately ditch the need "to guarantee Jewish rights and security" and start talking about guaranteeing the rights and security of all Israelis, the 20% Arabs in the population and the Christians, and the rest, alike. Anything less is not progressive and won't work. Your writer seems to be displaying the same old stale predictions to the same old stale scenario. If you don't start from the position that there is massive discrimination in Israel against non-Jews, Arabs in particular, you haven't a hope of solving this.
