Mark: Dad, what do you think about Attica? Phil: I think Rocky did the right thing...after all, what would you have him do - give in to that ridiculous demand of safe passage to a non-imperialist country? Think about it, son! What do you think would have happened to our relations with the Russians if they learned we were planning to parachute 750 hardened criminals into downtown Stalingrad?! Mark: Good point, dad. Phil: Darn right!
Attica is a New York prison which had a large prison riot at the time. “Rocky” is then-Governor Nelson Rockefeller who squashed the riot with armed force, resulting in many deaths.
