There have been a few just wars in the past. War can be justified if it is waged in order to defend yourself and your country and faith from invaders. War cannot be justified when it is offensive, instead of defensive. In other words, it is wrong to wage war if no one has attacked you or your country or your faith (eg. imperialist wars cannot be justified).
It is good to boost american morale. It will end the war sooner. Japan will never have the ability to go to war never again.
No. Discrimination is NEVER justified.
Slavery can never be justified.

This is an opinion question, there is not a specific answer. Look at the reasons that Germany and Japan went to war, and then you can determine for yourself if they were justified.
It is if the countries reason for war is reasonable
