Palestinians - PLO (especially Fatah), the Black September Organization (a Fatah-linked group), the PFLP, and later rejectionist factions like the Abu Nidal Organization (ANO/Fatah Revolutionary Council) - have attempted to challenge, undermine, or violently replace their host Arab governments.
Palestinian groups frequently operated from Arab host countries to attack Israel, or sought to assert sovereignty.
Jordan and Lebanon saw the most sustained attempts at dual authority or armed challenge; both ended in expulsion of Palestinians. Kuwait expelled 100s of thousands of Palestinians.
These countries know.
Palestinians tried and failed in Israel’s Arab neighbours.
So today, their attentions have turned to a weaker host to occupy and dominate: Europe.
