Was stopping the Nazis necessary?
Just as the title says, people can argue about Iraq and Afghanistan all they want, but what about the big one? What about stopping the efforts of Hitler and the Nazis to conquer Europe, exterminate the Jews, with them spreading the war to Africa and their allies Imperial Japan taking the war as far as America, or seeking a supernatural way to win the war and desicrating historical sites and writing Nazism into their history? Was it necessary to stop them? Why or why not?
