Why do ANY Nations Support a Palestinian Cause?

The West and the Israeli Left have been so consumed with finding peace with the Palestinian Arab nemesis for so long they all have forgotten why the West gave Zionists an opportunity to reestablish a nation of Israel.

Appeasement at any cost has given an unwarranted leverage to the Palestinians. The Palestinians do not exist to have their own nation. If they existed for nationhood the Palestinians would not be divided into groups ruled by psychotic warlords.

If the Mohammedans get their wish and destroy Israel and murder Jews, does anyone think surrounding Mohammedan nations will allow an armed divided Palestinian nation to exist? No! Syria, Jordan, Egypt and Saudi Arabia would carve out zones of influence and behead the Palestinian elites. I even imagine the Hashemite monarchs will duke it out with the Saudi monarchs over who controls Jerusalem.
