I agree with all of your points. In response to this statement,
"Even if the Soviet Union is gone from the world stage..."
I would refer you a quote from an article in the Wall Street Journal, page 1, Wednesday, February 23, 2005:
"Mr. Putin him self served more than 15 years in the KGB and later headed its successor, the FSB. Since taking over the Kremlin in 2000, he has presided over an unprecedented influx of ex-KGB men into the upper echelons of power---men whose formative years were spent learning how to undermine the West's interests.
Prominent among the ex-KGB officials who now pace the Kremlin's corridors are Defense minister Sergei Ivanov, Interior Minister Rahid Nurgaliev, and FSB chief Nikolai Patrushev, as well as the heads of Russia's arms-export, defense-procurement, and drug-enforcement agencies. A close Putin aide and former KGB man, Victor Ivano, serves on the board of flagship airline OAO Aeroflot. A favorite parlor game in Russia is to divine which other senior officials and businessmen have suspicious gaps in their resume that suggest a past with the intelligence services."
In other words, the Soviet Union is gone, but the organization that penetrated the West is alive and well, and ruling Russia!
Unfortunately, Golitsyn is 79 years old now (if alive) and his recent stuff does not focus on what is happening domestically in America, as I beleive it would if he was younger and more able to switch focus. However, he does mention the KGB influence on US society. His references, though few and brief, are telling.
