When Germany lost WW2

Many experts said that the war was lost for Axis after Kurz battle in 1943. Others point to the 1942 Stalingrad, while most German generals to the lost battle of Moscow in 1941. In my opinion, the war was lost in France. The surprising huge victory made Hitler think very high of himself. So high that he stopped listening to his generals. This resulted in a long series of strategic blunders which materialised in lost decisive battles. If von Manstein would have courage to remind Hitler that the plan for battle of France was his own (Aufmarschanweisung N°4, Fall Gelb) and not of Hitler. But, at that time, von Manstein was having some problems with his partly Jewish origins.
