[A Balrog of Morgoth]

the United States could not give the Japanese any warning, that although it could not concentrate on a civilian area, it should seek to make a profound psychological impression on as many inhabitants as possible.

Last time I checked, the Japenese weren't sitting on a stockpile of thousands of nuclear warheads in 1945.

IIRC, we DID give the Japanese warning about the nuclear attacks - leaflets and what not. If they didn't leave, that's their own fault.

The prototype A6M Zero was delivered to the airfield for testing in a ox-cart. This was because there was not a RR link between the factory and the airfield and the road between the factory and airfields was not metalled (paved), so aircraft delived in trucks were usually damaged in transit.
In the USA we would have called this a "clue."
