Btw it was economically rational for Germany to want to get strong expansionist & 'warry' since the Versailles Agreement probably meant they'd be made into a 3rd world or colonized country forever wouldn't they act upon it(there's a theory ww1 & 2 were actually the same ww). At the beginning of it too, if I'm not mistaken, their first aggressive actions were done on hoping to be able to keep the war localized as much as possible, that other countries would not want to pay the economic cost of chiming in(think Russia-Crimeia?), they didn't set out to start a World War, it just spun out of control. So obviously the categorization you made of "european supremacy" is void, since in the context it was irrelevant, they just saw themselves independently and seeking their own rational, economic, social, interests.
