In this week's Geopolitical Weekly, George Friedman discussed the geopolitical cycles that change with each generation . Frequently, especially in recent years, those geopolitical cycles have intersected with changes in the way the tactic of terrorism is employed and in the actors employing it. The Arab terrorism that began in the 1960s resulted from the Cold War and the Soviet decision to fund, train and otherwise encourage groups in the Middle East. The Soviet Union and its Middle Eastern proxies also sponsored Marxist terrorist groups in Europe and Latin America. They even backed the Japanese Red Army terrorist group. Places like South Yemen and Libya became havens where Marxist militants of many different nationalities gathered to learn terrorist tradecraft, often instructed by personnel from the Soviet KGB or the East German Stasi and from other militants.
