You’re rather more optimistic than I am ...
I agree with everyone.
The idustrial capacity of the USA was so great.
Just look at how much steel we produced in 1939
USA = 51.4 million tons
Germany = 23.3 million tons
USSR = 18.8 million tons
UK = 13.2 million tons
France = 6.2 million tons
Japan = 5.8 million tons
Italy = 2.3 million tons

We produced 9 times more steel than Japan in 1939
The subject was covered in a book called ‘Refighting the Pacific War’ published by the Naval Institute Press. Those scholars interviewed were unanimous in their view of the Japanese capability to successfully invade Hawaii - they simply lacked the assets required. They might have made it ashore, but not in a million years could they have stayed ashore.
Hitler might have helped Japan produce jets and other wonder weapons? It could have gone any way. If the war was fought by Todays America—we would have caved in 1946.
