The only hypothetical that works in this case is that Germany delays the invasion of France by a year, scuttles the idea of heading eastward into USSR and then stabilizes the northern Africa region for the oil. Maybe out of this scenario...they take the UK by 1944, with Japan never committing Pearl Harbor and the US stays out of the war entirely. Maybe by 1948, an invasion might occur with a stronger and more industrialized Germany. Although most economic guys will tell you....by 1942...they were insolvent and simply consuming other people’s cash.
The better what-if is if Pearl Harbor had never been put into the plans (the original idea would have avoided getting America into the war at all).
Yes. What if Pearl Harbor never happened, and Germany kept pursuing the technology they were pursuing (jets, the bomb) and achieved these while we sat on the sidelines?
