Both Castro and Krushchev came close to Bernie Sanders' Impossible Trident before Sanders was used by the Democrats to invoke it:
'Reading the speech in Pitsunda, Kruschev was astonished by its peroration. Castro had said, "The United States sponsored the attack because it cannot forgive us for achieving a socialist revolution under their noses." This was the first time in public that the Cuban had called his movement "socialist." The Chairman felt that tactically it "didn't make much sense" because it "narrowed the circle of those he could count on for support against the invasion." '
