"My letter to Castro concluded an episode of world history in which, bringing the world to the brink of atomic war, we won a Socialist Cuba. It's very consoling for me personally to know that our side acted correctly and that we did a great revolutionary deed by not letting American imperialism intimidate us. The Caribbean crisis was a triumph of Soviet foreign policy and a personal triumph in my own career as a statesman and as a member of the collective leadership. We achieved, I would say, a spectacular success without having to fire a single shot!"
