The National Security Doctrine consisted of a set of guidelines applied by the foreign policy of the United States in the context of the bipolar order of the Cold War, especially, during the phase known as détente. In doing so, United States supported the training of different Latin American armies in the School of Americas, in Panama, in counterinsurgency techniques and tools of repression. These techniques and tools were used a few years later by the dictatorial governments of the region. Focusing on practical geopolitics of the Southern Cone armies in the National Security Doctrine, this paper analyses the geopolitical practices and formal geopolitical models of those dictatorships. It is a good example of the internationalization of state terrorism to counteract the growing international links of the guerrilla movements.
