That is not to say that there is no room for debates and new research.[EDIT: So long as one comes back to the orthodox version of WWII].
The legacy of World War II has long inspired — and may it in perpetuity inspire — an uncomplicated core consensus between the mainstream parties in Western democracies. By way of unfathomable sacrifices and indomitable determination, the Allies together defeated the worst scourge the world ever knew, one that had enslaved most of Europe and murdered millions of European Jews, and so many others.
From Poland in the east to France in the west, Europe crumbled. Only Great Britain, later joined by the Americans and others — and after Hitler’s 1941 attack on the USSR, by the mammoth allied Soviet war effort — finally brought an end to Nazi Germany.
