This guy can't even get well-known history correct. The Cold War had just barely begun. The term "Iron Curtain" was less than 10 years old. I think they phrase it this way in order to make it sound like the Cold War was a figment of the imagination of those affiliated with McCarthy.
McCarthy started his hearings using a list of over 100 people in government positions which had been identified as members of specific Communist cells. Most of these people worked in the Department of Agriculture. They ALL resigned when confronted.
These people had been fingered by Chambers and a black woman whose name I cannot remember. Both Chambers and the black woman confessed that they had been members of these Communist cells. Chambers went on to help Nixon convict Alger Hiss.
The woman who insists on calling herself Queen Latifah voiced this same belief (that the Cold War was a hoax) on the View and did not have it explained to her that the Soviets were infiltrating countries, killing their own citizens, and arming for war and dominance. They propelled us into the space age.
