What was (in your opinion) the most important moment in WW2 which determined the future result of war?
I think that the November 1942 was such a moment.
The Soviets began a counter-offensive at Stalingrad, Americans landed in North Africa, British defeated Afrika Korps at El-Alamein, the 2nd battle at Guadalcanal took place and Los Alamos was selected as the site for an Atomic Bomb Laboratory.
Do you have other suggestions?
