This article doesn’t discuss WWI.
The history of what “led to” future events does NOT justify racist, genocidal world War by dictators.
Hitler indeed resented Germany’s loss in WWI, that does not remotely justify the Nazi party.
—
There is no justification, there are predecessor events that lead to where we are today.
The heavy reparations against Germany after WW1 led to the rise of someone like Hitler as a response to the burden of the German people. No reparations, and there would have been no Hitler.
No Kaiser and likewise no Hitler.
No Mrs Hitler as well.
No Bismark.
No Churchill.
No Eva Braun to float his boat.
No German Shepherd to make him happy and confident.
How about No Germany or German race for him to defend? “Blame” that on the Ancient Romans for losing to the Germanic invasions.
How about blame Hitler and the Nazis?
No, but it certainly made it possible for Hitler to gain the support of the German people.
