The story of the collusion between Castro and Argentina's anti-communist junta is also a story of the collusion between that right-wing junta and the late USSR under Brezhnev, which, from the early 1970s, was already busy selecting, preparing and training the future post-Soviet/anti-Soviet managers and cadres together with the CIA in places like Austria and elsewhere. This group was headed by then young Chubais, also included Glazyev, and, similarly, select ex-communist "dissidents" were also chosen and groomed elsewhere in Eastern Europe, i.e. in Czechoslovakia (Klaus, Zeman, Dienstbier, and others).

"[Fidel Castro] may even have funneled Soviet guns to the [Argentinian right-wing, anti-communist] junta. Moscow had its eyes on wheat and imported 20 million tons of Argentine grains between 1980 and 1985, flouting the U.S. grain embargo against the Soviet Union.
And so the Cold War took a strange turn in the Antilles, where a cynical left-wing dictator, blessed by the Kremlin, befriended a right-wing junta, and looked the other way when the generalissimos disposed of the bodies. Now history has brought them both out into the light, with Latin America the better for it."
