Stalin’s spies in Tokyo told him the Japanese were not going to confront the USSR so Stalin sent over 500,000 troops west to reinforce the Eastern Front. German intelligence picked up on that.
So if it made sense, it only made sense for a very short time and was a stupid gamble from the start.
And after Hitler declared war on the USA he knew they would eventually invade Europe, not join the Russians on that front.
The North Africa and Italian campaigns drew off critically needed German forces away from the Eastern front.
Ror many reasons Hitler was a bungler of the first degree.
The whole war was a stupid gamble on the Axis powers’ part. I said there was flawed reasoning behind it, not strategic genius. “The Wages of Destruction: The Making and Breaking of the Nazi Economy” by Adam Tooze throws a clear contrast between the economic power of Nazi Germany compared to the UK and US. They had absolutely no business starting a war, especially with their catastrophic lack of petroleum. And the Japanese were even more outclassed by the US economy. The whole thing was utterly mad. But aggressive tyrants gonna aggressive tyrant. Eyes on Ukraine and Taiwan...
Gamble by a bungler — not arguing this.
Could have worked, however.
