Two thoughts. First, it did OTL, when the German military wa shappy to have a hardon for Hitler and then joyously support him. There's enough continuity between the WW1 and 1930s officer corps to make me skeptical that this would be the case.
The Kaiser, BTW, was pretty much powerless by 1917/1918; anytime he opposed what the Silent Dictatorship did, they threatened to resign.
Why would it die due to internal political opposition when the military controlled the nation?
Forced drafts of Belgian labor to work in German factories, plans to resettle and ethnically cleanse parts of Poland, the Baltic, and the Crimea, attempts to confiscate Ukrainian grain...
Obviously, the differences are night and day.
Except as OTL's German foreign policy shows, they were led by idiots. Every time the liberals and Socialists tried to push for a compromise peace, the High Command essentially went LOL NOPE.
Which is part of why victory is night imposisble for these guys, but that's neither here nor there.
Declaring war on the US? Of course, the Germans in WW1 also discounted the US, and the frantic warnings from German businessman who spent time in America and knew what was coming.
