Why did I love this book?
Starting in World War II, American cryptanalysts broke Soviet codes and determined that hundreds of Americans working for the Soviet Union were active within the federal government during the New Deal and throughout the Second World War. Code named Venona, this operation was a closely guarded secret until declassification in 1996. When these intercepts were combined with information acquired from Soviet archives after the collapse of the USSR, they revealed not only a massive penetration of American government, science, and industry by Soviet spies but an American Communist Party that had assisted in these efforts, serving as an arm of Soviet intelligence. In other words (quoting American Communist Party member Alfred Bernstein), “[Joseph] McCarthy was right.” “The system was loaded with Communists.”
