The author states, "Had Japan annihilated the rest of the Pacific Fleet carriers, it would have taken Midway. With land-based planes on Midway, it would have taken Hawaii. With Hawaii well, who knows? Maybe San Francisco, maybe Alaska."
...and it's pretty damned tough to drive tanks across the Pacific. You are trying to make a point with apples and oranges...
Its not hard to drive ships across the Pacific. Our ship building capacity dwarfed Japan's. Note these tanks that we "drove" across the Pacific.
Well that was stupid on his part then....Japan never wanted to invade...they wanted to cripple us, sue for peace, and be allowed to keep China and some other territories.
