Germany goes democratic, WWII is fought against Stalin
i think not,
Weimar Republic was more hated by Right wing, communist and it politicians
like Reichspresident Hindenburg, who in public regular declare his dislike on this democracy !
Also many germans wanted back to good old day of Imperial Germany.
It would be the fight of Right wing vs Communist in 1930s
and the Right wings like Stahlhelm, organisation consul, Freikorps, Kampfbund, Wehrwolf with close tie-in with Reichswehr (military) could win this,
more likely the Weimar Republic could end in 1930s and be replace by a Monarchy in Germany.
and yes again, Germany start a World War to restore the border of Imperial Germany and get there colonies back...
