Israel can call itself what ever it people vote to call itself, a Jewish state or not, and security will come only once border are defined, so Netanyahu has is clearly trying to derail peace by making ludicrous demand of the Palestinians that serve no purpose.

Israel has a chance to earn its right to exist, whether it does so is completely up to Israelis.
