In many ways, November ‘42 is a major turning point of the war. Torch, upcoming events at Stalingrad, the rout of Rommel, Guadalcanal becoming hopeless for the Japanese.
Herman Wouk is among those who agree with your assessment. His fictitious German general character wrote the following in his "memoirs."
"The Global Waterloo was in fact a swift, roaring, flaming reverse all around the earth of our war effort, history's greatest - on the seas, in desert sands, on beaches, in jungles, in city streets, on tropical islands, in snowdrifts. In November 1942, the world-adventurer Hitler, to whom we Germans had given our souls, lost the initiative once for all. Thereafter the hangmen were closing in on him, and he was fighting not for world empire but for his neck."
