While Hashemite-Zionist relations and Maronite Church-Zionist relations have always been known and documented, there has been less documentation of the services that Israel has provided and continues to provide to Arab regimes over the decades. It is now recognized that Israel's 1967 invasion of Egypt aimed successfully to destroy Gamal Abdul-Nasser, the enemy of all US dictatorial allies among the Arab regimes, whom the US and before it Britain and France had tried to topple since the 1950s but failed. Israel thus rendered a great service to Arab monarchies (and a few republics) from "the ocean to the Gulf," whose survival was threatened by Nasser and Nasserism. Israel's subsequent intervention in Jordan in 1970 to help the Jordanian army destroy Palestinian Liberation Organization (PLO) guerrillas and its final crushing of that organization in its massive invasions of Lebanon in 1978 and 1982 were also important services it rendered to these same regimes threatened by the PLO's "revolutionary" potential and its sometimes recalcitrant positions. Israeli intelligence has also provided over the decades crucial information to several Arab regimes enabling them to crush their political opposition and strengthen their dictatorial rule. Prominent examples among recipients of Israeli intelligence largesse include the Moroccan and the Omani dictatorships.
