Abu Nidal as well as Achille Lauro hijacker Mahmoud Abbas, but i agree with your overarching point that both were relative small fry. That motherfucker Abu Nidal's organization murdered an extremely distant relative of mine, an Arab BTW. Went to school with some Iranian kids back in the 70s who were MeK militants. Saw one in the Baltimore area in the 80s, but i fear the rest may have perished at Evin prison.
