If there’s one thing the Russians are masters at, it’s intelligence. Their intelligence has always put ours to shame, even during the 80s. I still think the Soviet Union faked its own death
That’s not the opinion of the vast majority of former Soviet intelligence officers who have written books about their efforts against the US during the Cold War. During the 1930s and 1940s, however, the Soviets had much more success against us, primarily because of the many communist fellow travelers in the Roosevelt administration.
