Sarah Paine (prof at the us navy war college) made a great point in a video I saw a while back.
WW2 starts. The UK and US are already building prototype four engine bombers, what it takes to attack deep into the continent.
Japan, Germany? Nothing even on the drawing board, much less in prototype production.
Japan and Germany picked a fight with an industrial powerhouse, protected by two oceans, without the means to attack even the coasts of that country in any meaningful way. Literally, even if the entire imperial japanese navy went right for the west coast, they would have lost, and that's saying their logistics could stretch that far (they couldn't, literally didn't have the oil/gas).
The germans were even worse off. And even if you could slap the coasts, lol, what the fuck good is that going to do? There's THOUSANDS OF MILES of factories rail and resource extraction happening inside the US. It's the largest producer of refined petroleum at the time.
Japan and Germany never had a farts chance of striking detroit, pittsburgh, toledo, fort worth, hundreds of cities with thousands of factories and mines etc.,
WHAT KIND OF FUCKING MORON DRAWS AN ENEMY LIKE THAT INTO THE FRAY? How fucking dumb do you have to be lol?
