I'm beginning to realize what it was that's central to Jewish-Arab animosity since the beginning of the first millennium onwards.
Religion.
The Jews have Judaism, non-negotiable, the Arabs have Islam, non-negotiable, and never shall the twain meet.
Arab Christians and Israeli Christians, however, are bonded in love for each other just as Jesus commanded them, to 'love one another as I have loved you'.
Christianity, therefore, may be the key to peaceful co-existence between both Arabs and Jews, or Israelis, in the Middle East, not Judaism or Islam, both proven to be religions not of peace or love or tolerance but of violence, hatred and holy war in the case of one and vengeance and retribution in the case of the other.
