Stalin's Spies and The Secrets Of The NKVD

Very recommendable! You wonder if not Putin's Russia is not behind some of the mob violence and riots that have recently erupted in the U.S. Putin was a KGB officer and former director of the successor of the KGB!

It also tells the story what a paranoid monster Stalin was. He killed numerous spies and even the heads of his intelligence service!

Caution: Contains lot's of disturbing footage!
