When have these Arab countries ever supported Palestine? History informs us that the King of Jordan made secret deals with the Zionists. The Egyptians in 1979 betrayed the Palestinians. The Lebanese Christians murdered many Palestinians in refugees camps during the civil war. The Assad regime invaded Lebanon to destroy the PLO. The Abraham accords are further examples of betraying the Palestinians. Saudis have always been in the Zionist/US camp.
While I appreciate and find the support from the Houthis/Hezbollah very admirable, history informs us that the Palestinians must obtain the necessary means to liberate themselves. The Arab countries have proven themselves, time and time again, to be against the Palestinians. While we enjoy popular support, the regimes are led by despots.
