These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Values Dissonance: When a courier comes to tell Admiral Yamamoto about the Dolittle raid on Tokyo, the first subject brought up is the safety of The Emperor, and the hundreds of thousands of civilians who were in danger are not even mentioned.
Japanese officers' oaths were to the The Emperor (even if he was at least partly their puppet). To let enemies attack the homeland was bad, to expose your lord to danger (even though the palace wasn't a target) was unforgivable. Plus it undermined their justification for holding power. There was also the fact that the Japanese Emperor was a divine ruler(one of the problems with Japanese unconditional surrender after Hiroshima).
In fairness American soldiers would probably do the same thing if DC was bombed and the President was there. The Secret Service has this as their mandate.
