Stalin’s U.S.S.R. was already working to influence American politics, policy, education, entertainment, etc.
Did it pose a “threat” to US Security? Was any harm done by spies handing the Soviets the secrets to the atomic bomb?

Something either overlooked or completely beyond the realm of the typical PaulBot.
First you need a US administration that is not in bed with communism.
