"It wasn't until January, 1992, in a meeting chaired by Castro in Havana, Cuba, that I learned 162 nuclear warheads, including 90 tactical warheads, were on the island at the time of this critical moment of the crisis. I couldn't believe what I was hearing, and Castro got very angry with me because I said, "Mr. President, let's stop this meeting. This is totally new to me, I'm not sure I got the translation right." "Mr. President, I have three questions to you. Number one: did you know the nuclear warheads were there? Number two: if you did, would you have recommended to Khrushchev in the face of an U.S. attack that he use them? Number three: if he had used them, what would have happened to Cuba?" He said, "Number one, I knew they were there. Number two, I would not have recommended to Khrushchev, I did recommend to Khrushchev that they be used. Number three, 'What would have happened to Cuba?' It would have been totally destroyed." That's how close we were."
January 1, 1970
