I'm not going to Google any of this, but IIRC, Germany invaded Russia in June of '41, well before Japan attacked the US. And IIRC, Sorge told Stalin Germany planned to invade Russia, but Stalin refused to believe him and had him recalled and executed - not exactly genius on Stalin's part. And IIRC, Hitler decided to stop at the gates of Moscow and Lenningrad to divert his troops south toward Stalingrad on the way to securing the Caucases oil fields. Basically, Hitler's and Stalin's own haphazzard screw ups created this mess. I don't recall Heydrich having much to do with it, but I could be wrong.

FWIW, when I went to Prague in 1990, I found my way to Lidice, the village that was totally wiped off the map as reprisal for Heydrich's assassination. Very moving trip.
