I stayed on topic, discussing Germany, not Italy (which did nothing but hold Germany back until in the end Italy stabbed their supposed ally, Germany, in the back), nor Japan.
If you believe the victors' side of the story (which it seems that you do), you'd believe that Hitler was financed by Zionist Jews from the USA, or that Hitler himself had Jewish ancestry, or the stories about shrunken heads, lampshades and so on.
Is it inconceivable that an industrious and intelligent Germanic ruler and his people could manage to turn their country around solely on their own efforts?
I touched on 'territorial gains', which was nothing more than Germany reclaiming land lost at the end of WW1. The German government attempted on various occasions to negotiate with Poland to no avail, Poland had grand visions of expansion and since they believed that they had England and France to back them up, they became very emboldened and arrogant. Having your people uprooted, beaten and murdered isn't a justification for war?, how many times has the USA bombed nations because of American loss of lives or intervened when Americans overseas are threatened?
Poland was used by its 'allies' as a pawn for starting WW2, the Poles were simply too stupid to see it and were dropped like a leper when her 'friends' got real cosy with 'Uncle Joe'.
