The Palestinians were a group of lowlifes fighting Jourdan with Arafat as their leader. 27,000 of them were killed by Jordanians and pushed them into Israel.
Actually the fled to Lebanon where they destroyed the country. One of Reagan's mistakes, intervening to save civilian lives, but also to save the PLO and Arafat's behinds. Plenty of other terrorists, but the world could have been done with them then.
