All,
Having read a lot about Heydrich on BBC, I came to wonder:
Heydrich was surely one of the most cruel and "effective" SS leaders.
Was he threatening Himmler?
Was Himmler involved in letting the assassination happen?
Could Heydrich have toppled Himmler and would he?
How would it have looked if Heydrich was head of SS, also Waffen SS?
