There aren't. Most of supposed "Palestinians" were just people who long lived in Jordan, and then were driven out. "September 1970 is known as the Black September in Arab history and sometimes is referred to as the "era of regrettable events". It was a month when Hashemite King Hussein of Jordan moved to quash an attempt by Palestinian organizations to overthrow his monarchy. The violence resulted in heavy civilian Palestinian casualties. Armed conflict lasted until July 1971 with the expulsion of the PLO and thousands of Palestinians." The current Palestinians are just a mix of Arabs that attacked Israel in 1948 and were forced to retreat, and the aforementioned Jordanian exiles. Here's a good joke: Begin and Araffat walk into a bar. Begin starts telling a joke about why Abraham had really red feet. "What happened to his feet?" Araffat asks. "A Palestinian stole his shoes," Begin replies. "That's crazy! There were no Palestinians in Israel back then!" "Exactly."
