The start. The treaty of Versailles had many things in it it that Germany did not follow. Such a deconstruction of many of their higher ranking military personal but they kept many of them on secret. And allowing foreign powers to occupy their land, they encouraged people in those areas not to comply with the occupation
The worst thing to happen to Germany is the economical toll but again this was not overly harsh
Germany did in fact escalate what was a local central European war to a world War by invading neutral Belgium among other things
Germany also committed atrocities involving chemical weapons and mass executions. So they did not show honor in the war
I think it’s possible that Germany would of not started ww2 itself but I don’t think ww2 would of not happened. Perhaps Hitler would never rise to power but you still had Japan Italy and the Soviet Union who would of ended up starting ww2 anyways
Even if Germany was spared having to pay reparations, it’s likely that a hitler like figure would rise because the country had been in horrible shape even without the treaty of Versailles
