The Arabs supported Hitler and his policies against the Jews. The Baath party that runs Syria and use to run Iraq was a neo-Nazi political party prior to coming to power in those countries. Even Egypt had its Nazi supporters reporting everything to German intelligence, so what makes the Palestinians any different nothing they wanted Germany to supply Arab Palestinians with weapons to fight the British and to push out the Jews. Mufti of Jerusalem, Haj Amin al-Husseini was a Palestinian and he courted Hitler and meet face to face with Eichmann, so there?s definitely a history there.
