We know for sure that KGB was one of the most effective secret security service in the world in their time, and their biggest rival was CIA. KGB is known for working legally and illegally, not just controlling the people who live in Russia, they also had great activity outside the country with spies and secret agent with all kinds of techniques.
Apparently the idea is the new ministry to be created by merging FSB (Foreign Intelligence Service) and SVR (Federal Security Service) to become One, that would be named 'MGB' Ministry of State Security (The same name as former KGB).
