“Someone correct me if wrong but did not Austria cater to the Germans in WWII?”
They were incorporated into Germany in 1938. In the 1860s two German states (Austria & Prussia) battled for supremacy of the hundreds of smaller German entities, and Prussia won. While they led the new Germany formed in 1871, Austria looked south for an empire (Austria-Hungary, which collapsed after WWI). In 1938 the much smaller Austria joined Germany; as German troops crossed the border to make it so, there can be some questions about Austria’s complicity in it. The allies, who had said this couldn;t happen at the end of WWI, did nothing.
Well, Hitler was Austrian, so it appears in the end, Austria won. Hitler despised everything about Prussia.
