The Jews of Israel have moved (or their parents have moved) into a part of the world where they are hated and reviled, and the local population lusts for their spiritual and physical extermination.
Many of them would like to rely for their safety and simple physical survival on "decency", or "international law", or a "right to exist" which could be granted by some nonexistent authority.
In fact, they must, if they are to survive, rely mainly on the willingness of the Jewish people to employ brutality against their many enemies, essentially forever.
I'm not sure this is such a good bet.
"The Jews of Israel have moved (or their parents have moved) into a part of the world where they are hated and reviled, and the local population lusts for their spiritual and physical extermination."
Leaving aside the fact that around half of Israel's Jewish population came from the Middle East (having been ethnically cleansed by the Arab nations) and a large number have lived there for many generations, you seem to forget that the remainder came from a continent whose peoples had not just lusted for "their spiritual and physical extermination," but had actually nearly achieved it.

This article is not about the Arabs, but Israel's many enemies in the West who are collaborating with those who wish to destroy her.
