In politics, a defector is a person who gives up allegiance to one state in exchange for allegiance to another, changing sides in a way which is considered illegitimate by the first state.

Penkovsky informed the United States and the United Kingdom about Soviet military secrets, including the appearance and footprint of Soviet intermediate-range ballistic missile installations and the weakness of the Soviet intercontinental ballistic missile (ICBM) program. This information was decisive in allowing the US to recognize that the Soviets were placing missiles in Cuba before most of them were operational. It also gave US President John F. Kennedy, during the Cuban Missile Crisis that followed, valuable information about Soviet weakness that allowed him to face down Soviet leader Nikita Khrushchev and resolve the crisis without a nuclear war.

As early as the 1920s, the Soviet Union, through its GRU, OGPU, NKVD, and KGB intelligence agencies, used Russian and foreign-born nationals, as well as Communists of American origin, to perform espionage activities in the United States, forming various spy rings. Particularly during the 1940s, some of these espionage networks had contact with various U.S. government agencies. These Soviet espionage networks illegally transmitted confidential information to Moscow, such as information on the development of the atomic bomb. Soviet spies also participated in propaganda and disinformation operations, known as active measures, and attempted to sabotage diplomatic relationships between the U.S. and its allies.

It was the direct successor of preceding Soviet secret police agencies including the Cheka, OGPU, and NKVD. Attached to the Council of Ministers, it was the chief government agency of "union-republican jurisdiction", carrying out internal security, foreign intelligence, counter-intelligence and secret police functions. Similar agencies operated in each of the republics of the Soviet Union aside from the Russian SFSR, where the KGB was headquartered, with many associated ministries, state committees and state commissions.
