some Kurds in Syria, the People's Protection Units (YPG), which is a sister organization of Turkey's Kurdistan Workers Party (PKK). The PKK is listed in the US Department of State's Foreign Terrorist Organizations list, and described as "a US-designated terrorist organization" in the CIA's World Factbook, but the YPG is not. Union of Soviet Socialist Republics Soviet secret services worked to establish a network of terrorist front organizations and had been described as the primary promoters of terrorism worldwide. According to defector Ion Mihai Pacepa, General Aleksandr Sakharovsky from the First Chief Directorate of the KGB once said: "In today’s world, when nuclear arms have made military force obsolete, terrorism should become our main weapon." Pacepa further claims Sakharovsky stated that "Airplane hijacking is my own invention" and that George Habash, who worked under the KGB's guidance, explained: "Killing one Jew far away from the field of battle is more effective than killing a hundred Jews on the field of battle, because it attracts more attention." Pacepa described an alleged operation "SIG" ("Zionist Governments") that was devised in 1972, to turn the whole Islamic world against Israel and the United States. KGB chairman Yury Andropov allegedly explained to Pacepa that "a billion adversaries could inflict far greater damage on America than could a few millions. We needed to instill a Nazi-style hatred for the Jews throughout the Islamic world, and to turn this weapon of the emotions into a terrorist bloodbath against Israel and its main supporter, the United States." The following organizations have been allegedly established with assistance from Eastern Bloc security services: the PLO, the 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), the Democratic Front for the Liberation of Palestine (DFLP) in 1969, and the Armenian 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. The secret training of PLO guerrillas was provided by the KGB. 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 Russia. Led by Carlos the Jackal, a group of PFLP fighters accomplished a spectacular raid on OPEC headquarters in
