Exactly ! I couldn't have said it better : "To ensure the survival of the Jewish state, we need to have a Jewish majority." This is why it is so essential a Palestinian state should be established at the earliest date possible. Amy Ayalon, former chief of the Israeli Navy and then former head of Israel's Intelligence Agency (Shabak), has already said that, the first time on December 22, 2001 : "Only a Palestinian state will preserve the Jewish and democratic character of Israel." And this is why also, Israel will have to return to its 1967 borders. The sooner the better. As you said.
