Arcane Art of Kremlinology Remains Relevant for North Korea Eunjung Cho A veteran practitioner of the arcane art of "Kremlinology" says the skills honed to decipher what was really happening in the ruling circles of a secretive Soviet Union remain useful today in trying to determine what is up with North Korea's leadership. "North Korea is the last bastion of the old Soviet-style communism," says Alexander "Sandy" Vershbow, U.S. ambassador to Russia from 2001 to 2005. "There is some intelligence collected about internal developments of North Korea, but it's still opaque. So the old techniques applied to the Soviet Union are still relevant to today's North Korea." Vershbow, who also served as the Soviet Union affairs director at the State Department during the last days of the Cold War, had his first foreign posting to Moscow in 1979, as a second secretary at the U.S. Embassy. .
