Yuri Bezmenov (aka Tomas Schuman) was a Soviet journalist and former KGB informant and defector.
Yuri Bezmenov worked as a “journalist” for Novosti Press Agency, which was a disinformation and propaganda agency controlled by the Soviet non-military intelligence agency (commonly known as the KGB).
The Soviets called their disinformation work through Novosti “active measures,” though Schuman uses the phrase “ideological subversion” to describe the activity of Novosti. Actually, “ideological subversion” was more of a term used by Soviet and Soviet-bloc propaganda to characterize the supposed actions of the West to undermine socialist and Communist ideology within the Soviet Union.
In the fifties and sixties, the Soviets and their allies began to use more creative means to mislead and misinform the West and the Third World, creating a cumulative effect that would in the long term be favorable to the Soviet Union.
