Trotsky was writing his biography of Stalin when he was attacked. There was blood all over the manuscript.
The book had to be published by a small press in paperback because the big publishers in New York were so infested with Communists that they refused to publish it. The same thing happened to George Orwell’s Animal Farm.
A few years later, of course, the same people were screaming about “blacklists” and “censorship.”
There is also a very detailed version of the story in
“The Venona Secrets”-by Herbert Romerstein and Eric Breindel,using the decripted secret diplomatic messages between the Soviet Union and it’s agents here.
Stunning history.McCarthy was right.
