Lt. General Pacepa described operation "SIG" (“Zionist Governments”) that was devised in 1972 to turn the Arab world against Israel and the United States. According to Pacepa, the following organizations received assistance from the KGB and other Eastern Bloc intelligence services: PLO, National Liberation Army of Bolivia (created in 1964 with help from Ernesto Che Guevara), the National Liberation Army of Colombia (created in 1965 with help from Cuba), Democratic Front for the Liberation of Palestine in 1969, and the Secret Army for Liberation of Armenia in 1975

The leader of the PLO, Yasser Arafat, established close collaboration with the Romanian Securitate service and the Soviet KGB in the beginning of the 1970s.[9] The secret training of PLO guerrillas was provided by the KGB.[10] However, the main KGB activities and arms shipments were channeled through Wadie Haddad of the DFLP organization, who usually stayed in a KGB dacha (BARVIKHA-1) during his visits to the Soviet Union. Led by Carlos the Jackal, a group of PFLP fighters accomplished a spectacular raid on the Organization of Petroleum Exporting Countries office in Vienna in 1975. Advance notice of this operation "was almost certainly" given to the KGB

Transfer of machine-guns, automatic rifles, Walther pistols, and cartridges to the Official Irish Republican Army by the Soviet intelligence vessel Reduktor (operation SPLASH) in 1972 to fulfill a personal request of arms from Michael O'Riordan.

Transfer of anti-tank grenade RPG-7 launchers, radio-controlled SNOP mines, pistols with silencers, machine guns, and other weaponry to the Popular Front for the Liberation of Palestine through Wadi Haddad, who was recruited as a KGB agent in 1970 (operation VOSTOK, "East")
