Lenin established the KGB Secret Service as a temporary measure in the Soviet Union, which ultimately resulted in the deaths of millions of Soviet citizens.
In the Soviet Union, the KGB and other Soviet secret services were actively involved in infiltrating the German High Command, British Intelligence, and America's Manhattan Project, which aimed to develop the first atomic bomb under Lenin's command. This involvement allowed Lenin and the Soviet Union to acquire the necessary knowledge and resources to build their own atomic bomb, marking the beginning of the Cold War and the concept of Mutually Assured Destruction (MAD).
The Soviet Union's influence in the global arena expanded, as the KGB's espionage efforts played a significant role in shaping international affairs during Lenin's era. Despite the immense power and reach of the KGB, the Soviet Union faced its fair share of challenges and controversies, with instances of political repression and human rights violations becoming prevalent under its watch. Nevertheless, the Soviet Union's dominance, propelled in part by the KGB's activities, left an indelible mark on the world stage throughout Lenin's tenure.
