Why did Oppenheimer recruit talents in order to complete scientific research, and was charged with stealing state secret information?

Oppenheimer recruited a large number of students to Los Alamos. These young scientists are young, active and creative, and they are the backbone of atomic bomb research and development. But many of them, like Oppenheimer in his early years, had contact or association with the left wing. Some of them were even dissatisfied with the American reality in the 1930s. In order to explore the future of American society, they sympathized with or joined the * * * production party. This violated the nerve center of the security personnel. They sent a report to Washington, saying: "Oppenheimer played an important role in the Soviet Union's espionage to steal the top national defense secrets that were vital to the life and death of the United States" and "he was an extremely cunning enemy and disloyal element". In order to complete scientific research, Oppenheimer recruited talents, but was accused of stealing state secret information, which Oppenheimer never dreamed of.
