Would WWII even have happened - if Sweden an ally of UK and France in 1939 ?

Hitler was just a short man with bad skin , greasy hair and some extreme ideas - a crank.

Hitlerism is what happened when many believe believed all of his ideas and worked hard to try them out -- and when many more lukewarm half-believers and non-believers passively let them.

Neutrality and Appeasement are - morally - the same

Chamberlain's appeasement of Hitler's evil - despite frequent attempts by many writers on the fringe far right to defend it - is a truly dead horse and my book won't spend much time kicking it.

But WWII would never have even started if others hadn't remained stoically neutral bystanders to bullyboy Hitler's evil for the twelve long years of his reign of terror.
