Before world war two some people belived that if women were in charge that it would be a world with out war. When the first female Chancler of germany rode into power on the heels of the far right wing Nazi power some people hoped that she would be a peaceful moderating factor in the nazi party.
50-80 million deaths later, after europe was turned into a charnel house no body belived that at all.
But what if she had been born a man instead of a woman, still did all the same things still performed all the same attrocities and just had her gender changed? How would that change the world?
