A probing interview by CNN’s Pat Mitchell with a key surviving protagonist from the TV series, "The Cold War." Who won the Cold War? In this astonishingly frank interview, Fidel Castro makes some remarkable revelations about the conflict that took the world to the brink of annihilation. Far from being a proxy for Moscow, Castro tells CNN that Cuba’s support for liberation movements in Latin America and Africa was a "constant source of disagreement" with the Soviet Union. "If a Soviet Cuban master plan had really existed we would have won the Cold War!" he says. The Cuban leader’s reflection on talk of US pre-emptive nuclear strikes during the 1962 Missile Crisis seems frighteningly familiar today.
