I found this interview with a former CIA and KGB somewhat interesting.

Former CIA and KGB agents share inside look at espionage

Redmon was a CIA agent

Redmond acknowledged the KGB’s deep penetration into the U.S. government during the Cold War. He said if the Soviets had not collapsed and a military war resulted, the United States would have lost.

“When you look at what would have happened if there was a war, it was terrifying,” he said. “We would have lost because the Soviets and the Hungarians had the lot.

“When you look at the Soviet shuttle, it’s ours. The holes for the bolts are in the same place right down to the last millimeter.”
Kalugin was KGB

Kalugin’s speech centered on KGB methodology and ideology. He said during the Cold War, the Soviet government was focused on the United States as its number-one enemy. The KGB received solid support from the government, which asked no moral questions about the KGB’s actions and policies.

“We conducted a clandestine war with assassination if necessary,” he said. “Our mission was to do everything we could to have a war without the fighting. This was seen as amoral in America, but it was our ideology.”
AND

Kalugin listed several astonishing facts from a classified KGB report, proving just how much the organization is committed to counterintelligence. He said that in 1981 the KGB reported that they had funded or supported 70 books, 66 feature and documentary films, more than 100 television stations, 4,865 articles in magazines or newspapers, 300 conferences or exhibitions and 170,000 lectures around the world.
They thoroughly infiltrated our media and universities, they may have won the long war if they weren't so corrupt and clinging to a bankrupt political system.
