There was serious talk that Cuba would be swept up in the general good will of detente and the embargo instituted in 1964 by the Organization of American States would be lifted. Mr. Szulc vigorously supports such a move; Mr. Mas vigorously opposes it in any form that it would be likely to take in the current climate ("as it appears now, they go to Cuba on bended knee; I'm just about sure that Castro is going to be the winner in the long run"). This debate sometimes bogs down in accusations (of narrowness; of fellow traveling), but we still learn a lot about the way Cuba fits into the world scene, A.D. 1974.
