I'm going to preface my answer by saying that the mods might strike you down for a "poll-type" question. If the mods give this thread the big "Okay", then I'll delete this and answer you in full.

Alas, The_Western is right. It's a poll-type question, and against our rules. Ask instead something like "How did the [insert the name of the front of you, catmandoo123's, choice] theatre of the war help defeat the Nazis?"
