Opinion outside Israel is worthless as far as the survival of Israel is concerned. The Israelis know that in the last resort they must rely only upon themselves.
So far, the only solution acceptable to their opponents is that the Israelis should roll over and stop breathing.
Until that policy changes, and it dates officially from the 1920's , the Israelis will continue to defend their corner as they feel necessary; they have little choice in the matter but to stay strong, even though much of the world would find it most convenient to sell them down the river.
Lecturing the Israelis on how to handle their Middle Eastern opponents is like trying to teach your grandma how to suck eggs.
They have drawn a common-sense line in the sand, all things can possibly spring from that point.
