Context .....
The Japanese killed less than 3% of the Chinese population, and less than 2% of the Korean population.
By comparison the US (
and it's allies) killed 8% of the German population, and 4% of the Japanese population.
The US lost just 0.3% of it's population ....
So if the Japanese were
'ruthless killing machines' then what the feck does that say about the Americans?
Interestingly despite all the movies about the blitz, d-day, dunkirk because the UK was never actually invaded less than 1% of the UK population were killed by WW2.

History is written by the winners, both sides were ruthless killing machines, both sides fought dirty ... the US just did a much better job.
Sorry very off-topic ...
