Bourgeois historians dismiss anybody arrested in the Soviet Union for being a spy or a counterrevolutionary as innocent. But were there no spies and saboteurs in the Soviet Union? Was everyone persecuted by the state a good-willed political opponent and not a spy? History says otherwise.

“After the October Revolution the Bolsheviks were able to read the Okhrana files. They discovered that [Roman] Malinovsky was a spy and on his return to Russia in 1918 he was arrested. At his trial Malinovsky admitted he had been a spy and commented: ‘I am not asking for mercy! I know what is in store for me. I deserve it.’ After a brief trial was found guilty and executed.”
