If you still have a copy of the important 1976 volume by Alexander Solzhenitsyn, A Warning to the West, it will be worth your while to find it, blow off the dust, and revisit it – as I have just done. In it are five talks the Soviet dissident gave in the United States and Britian during 1975 to 1976. 

Since my focus here is actually on a North Korean defector who is likewise sounding the alarm, let me briefly offer two quotes from Solzhenitsyn before moving on.
