Palestine is many things. A Roman name and a Cold War lie. Mostly it’s a justification for killing Jews.
Palestine was an old Saudi-Soviet scam which invented a fake nationality for the Arab clans who had invaded and colonized Israel. This big lie transformed the leftist and Islamist terrorists run by them into the liberators of an imaginary nation. Suddenly the efforts of the Muslim bloc and the Soviet bloc to destroy the Jewish State became an undertaking of sympathetically murderous underdogs.
But the Palestine lie is past its sell by date.
