The alternative to negotiations, including concessions, is a policy of telling the Palestinians, and through them the rest of the Arabic and Islamic world, that Israel will make no compromise and there is therefore no reason to even try to negotiate with Israel, and that they are better off concentrating on how they can best destroy Israel, so it is an “all or none, no compromise issue”. Should Israel tell the majority of the Arabs (who have made peace with Israel) that they deceived?
Of course, we can rely on the zechus of the zionists and hope Ha-Shem makes a miracle, but that might prove to be an unwise policy decision.
