Let's not forget Black September.

The Death of Black September
On 1 March 1973, an eight man Black September hit squad shot their way into the Saudi Embassy in Khartoum where a farewell party was being held for American chargé d’affaires J. Curtis Moore. They took the guests hostage and made the usual demands for the freeing of prisoners in several countries. It was an affront to Sudan’s President Ja’afar Numeiri, the man who had saved Arafat during the fighting in Amman, an insult to the Saudis, who had continued to fund the PLO, and a direct threat to American diplomats. The negotiations with the semi-literate terrorists got nowhere and the grisly episode ended with the cold-blooded murder in the embassy basement of Moore, the American Ambassador, Cleo Noel, and the Belgian chargé d’affaires, Guy Eid.
The terrorists were in radio contact and receiving instructions from Beirut during the day long siege but the Israeli claim that Arafat personally gave them orders, has never been verified and consequent events suggest it was untrue. The Israelis failed to produce the tapes of Arafat issuing instructions; the American monitoring of the operation produced nothing to incriminate him. Arafat despatched an emissary to the Sudan to mend relations with that country. The brutality of the attack disgusted the world. Public opinion had turned even more against the Palestinians and Arafat was on the defensive.
The Israelis were not going to take Palestinian terrorist attacks lying down and went on the offensive. Following the Munich massacre the Israelis sent out hit squads to take out those involved, the Israelis managed to assassinate two out of the three Palestinians that survived the shoot out at Munich and the Israelis also managed to liquidate at least a dozen others involved in the planning. Israeli actions reached a climax in March 1973 in the form of Operation Spring of Youth, the assassination by an Israeli hit squad in Beirut of PLO terrorist leaders Kamal Adwan, Mohammed Yusuf Al Najjar and Kamal Nassar.
All of this was now too much for Arafat, his top terrorists were dropping like flies and all the attacks had achieved was a popular distaste towards the PLO and the Palestinians. Arafat decided it was time to quietly halt terror attacks against the West and so Black September for the most part vanished quietly into the night but its members continue to be hunted down.
Even though the West was to be spared Palestinian terror the Middle East was not to be so fortunate and Lebanon was to suffer more than any other country at the hands of the Palestinians whose actions and those of their allies resulted in fifteen year war and the destruction of the Lebanese state.
