Actually it was Samson who slew the philistines with the Jawbone of an ass. King David, used a slingshot. Slaying philistines was good for the ancient Israeli kingdom. Now, who are the so called Palestinians? Why they are Jordanians, Egyptians, and Syrians. Now, why didn't the Israelis let those who lived in that geography stay after 1948, while they did. However, a large number of them heeded the warning of the three previously mentioned nations to get out so that the Great arab nation could whipe the Jews from the land in a great war. Those folks said, great idea and left becomeing displaced persons. The problem was, the Israelis cleaned the clocks of the numerically superior Arab nation leading to humiliating defeat. The displaced persons were then given refuge in several Arab countries. They under their leader yasser arafat, promptly tried to overthrow and seize control of those governments and with communist backing tried to replace the monarchies. They were put down and successively kicked out of several nations. The Israelis, in a bid for peace with their neighbors, offered the squatters the land which they had captured from Jordan and Egypt in a series of wars started by those Arab nations. Jordan and Egypt thought it was a great idea since it seemed to solve the problem of all three nations. Lebanon breathed a sigh of relief since the so called palis had pretty much trashed a nation that had been a paradise. All looked well. The problem was the Palis took the land but continued the attacks in Israel since they were not satisfied to have their own government and land. You see, they had no intention of having a country, they just wanted to have war. It is profitable, foreign nations who liked to keep the pot stirred sent them funds ( USSR, Iran, Iraq, Libya) and arafat, having made himself a warlord would just not do well without a war.
