Relationship with PLO

Starting in the 1960s, many Iranians (both leftist and religious) had volunteered to fight against Israel with various Palestinian organizations,

Since the 1980s there has been an ongoing proxy conflict between Iran and Israel. Until 1979, motivated by the periphery doctrine, Imperial Iran and Israel had close relations, seeing Arab powers as a common threat. While some covert ties continued during the Iran–Iraq War, formal relations between the two countries terminated after the 1979 Islamic revolution.
