>>We look back and say that it was unjustified -
I’m not sure that we do. Look back, that is. It is widely said today that it was evil/racist, but have those doing so really looked back? In a total war of that magnitude, given what was known about collaboration via our breaking of Japanese codes, was it really the wrong thing to do, overall?
Required reading on the subject. Lots of scans of source documents from the era:
