Interesting. 1945 was, indeed, a good year.
A lot of people committed suicide in Germany in 1945 due to their treatment by the Soviets, in particular women and children who were mass raped by Soviet soldiers. The same happened in Hungary. In many respects the Soviets were little better than the Nazis in their treatment of civilian populations.
I take the suggestion that most of the suicides did so because they couldn't live outside of the Nazi regime with a 'pinch of salt'. Most former Nazis did not kill themselves, and the high profile ones that did most likely committed suicide rather than give the victors satisfaction in killing, torturing, or imprisoning them, thus suicide was a rational and clean end for themselves. This type of historical revisionism is just as stupid and dishonest as the BS put about by people in denial about the Holocaust.
In my opinion, the premise behind the suggestion is likely utter BS, wishful thinking, and pandering to an agenda that is not concerned with reality. A "U571" moment (the Hollywood fictional film about the enigma code), if you will.
