I would argue the opposite. The EU showed that Germany had won the war.
If people would look deeper into the postwar actions, they would see that such was the case. The formation of the European Coal and Steel Community so rapidly after the end of the war was one indicator. Installing Konrad Adenauer as chancellor of West Germany, and doing thing such as looking the other way while he put certain people in positions of power (with certain unrepented-of ideologies) and handing de-Nazification to his government after a mere two years is yet another and a huge one to boot. The rapid rise of leftism within Britain and the USA was yet another; more rapid in the UK (nationalization of key industries and the railroads, abominations like the 1967 Abortion Act) but still rapid enough in the USA (imitation of the autobahn system with the interstate highways, the Great Society, ad nauseam).
