If you read about Yamamoto, he actually lived/studied in the US before the war and was reportedly against the war-planning by his superiors. I’m sure he was aware of our industrial potential.
Kinda of makes you nervous now. I wonder how hard it would be for us to tool up for a major conflict like that? But, I guess major conflicts like that are less likely with nukes in the mix. I believe we had 100 aircraft carriers in service at the end of WWII. Granted, they weren’t all big carriers, but that’s absolutely amazing.
Not looking to start anything political. Way too much that stuff.
