Today's EU, geographically, is about as big as were the eight 'big' nations of WWII.
Hold that thought for a moment or two.
If we consider the 1940 version of the Indian empire and not today's India, they definitely included Russia , Canada, China, America, Australia, Brazil and perhaps India and perhaps British southern Africa -South Africa and Rhodesia and Kenya etc.
Japan and Germany , France and Italy were not among them. - no Europeans in the lot.
