What was the turning point in WW2?

Historians would argue about that, but possibly it's Pearl Harbour, which brought the huge resources of America into the Allied effort. Please, someone, have a different opinion!

Umm I think ummm.....:(the battles of Kruse and Stalingrad) (or the sucessful landing in normandy)YAY USA

If just two of us can disagree so widely it indicates that, as with so many historical matters, there is seldom one all-embracing event that can be called the only turning point.
