It's interesting how much worse off the world would be if the smartest people were in charge of it.
What ultimately blocked his nuke proposals? (Why didn't anyone listen?) I'm curious about whatever failsafe that was.
2. Probably what blocked his proposals is that most people are loath to murder millions of other people (especially if they have ~any other option, including "do nothing")
While it's easy to dismiss that view in hindsight, it's worth considering that von Neumann had personally witnessed the rise of the Nazis and had to flee along with many of his friends and family. And he had seen that regime defeated only by military strength of the USA. And while the USSR and USA never did end up in a nuclear war, it really was only by a series of miracles that it was avoided. I think most historians of the 20th century would agree we got very, very lucky.

As an extreme example, antisemitism was so commonly palatable that an open admirer of Hitler, Charles Lindbergh, was a very serious candidate for the presidency.
Today, open antisemitism can get one's career derailed in much of the world. Would that be true without the eye-opening shock that the news of the concentration camps produced?
IN NOW WAY was the Holocaust forgivable, but we simply cannot say if the world today would be "more moral on average" or "less moral on average". Maybe Jews would feel and be far less safe today in predominantly Christian countries. Maybe not.
All we can say for certain is that the horrors enacted upon the Holocaust victims were evil. As we can surely say that murdering many millions of people living in the USSR would be.
