Actually, the NKVD was "reformed" out of existence under Kruschev. In fairness to the FBI (or even Homeland Security) they are not (yet anyway) running large internment camps for political prisoners.
The KGB certainly was mainly in charge of counter-espionage and foreign intelligence operations (FBI and CIA, respectively), as well as border security (Customs/ICE), but we learned, upon the collapse of the Soviet Union, that the KGB had many "Directorates" whose job was specially to watch the Soviet Government, and Party, itself. To watch all members make sure no threats came from INSIDE the government and party itself - this is exactly what the DOJ/FBI do now.
“Actually, the NKVD was ‘reformed’ out of existence under Kruschev.”
Which is why I said it no longer existed, at least under that identity. But my comparison of the FBI to the NKVD was in reference to their national roles (they were both akin to national police forces); I did not compare their respective means and powers.
Remember, I was replying to YOUR comment that the FBI is America’s KGB, that they were both the state security systems of their respective governments. That is simply not true. The KGB was the Soviet Union’s foreign espionage agency, just as the CIA is for the US. The KGB was not the Soviet state security system (the NKVD was); just as the CIA is not the American state security system (that role belongs to the FBI and some other federal agencies). KGB’s primary mission was foreign intelligence and counter-intelligence; and as an adjunct, but subordinate role, border security and guarding some bigwigs.
