I'd add that Germany cannot be construed to have started WW1 in any way, shape or form by any logical human being thinking about the situation in good faith. Its immediate trigger was the assassination of the Austro-Hungarian crown prince by a Serbian terrorist, we could talk for hours about the underlying causes but that's what set the actual start of the war in motion. Even if one were to try to argue that Germany shouldn't have stood by Austria-Hungary and issued its 'blank check' for retaliation against Serbia, by the same logic Russia should be held more responsible for starting the shitstorm on account of it mobilizing to defend its pet Serbia - an unambiguous state sponsor of terrorism which just murdered the future head-of-state of a Great Power.

The war guilt clause was obvious bullshit even back in the day, something even the French (the most vindictive of the Entente Powers) understood but just didn't care about, and I daresay the Nazis and in fact every other stripe of German nationalist out there (because even some democrats weren't willing to accept it and at least bleated about getting a slightly less shit deal, ie. Wilhelm Solf and Philip Scheidemann) were entirely justified in their grievances against it.
