Did you know that at the end of World War Two in Europe, well over a million Russian POWs, that had been held by Germany, and liberated by the Western Powers, were returned to Russia? Every one was sent to the gulags, on the fear that they might have seen the wealth of the West, and only a few hundred ever returned home.

The Soviets killed their own POWs, when they were returned...

Source? Aleksandr Solzhenitsyn, The Gulag Archipelago 1918-56

This book should be required reading in high school. EVERYONE should understand the evils of communism.
