I guess for some, it all depends on the numbers.
It would take more time than I have today to address some of the issues in this thread.
John, it was all wrong, MHO, but it's never such a simple answer, is it?
Half my daughter's heritage is Japanese. I have a few stories, but mostly about the first and second generation in the US. B'chan and G'chan never talked much about preWWII Japan, but not because they didn't want to. Rather, it was to move forward into a new mindset with the children they birthed here in the USA, including my best friend and her eldest sister, born in a relocation camp.
Wrong to fry people alive with the most destructive weapons on earth? Yes. But it's just as wrong to torture them in any other way.
Was it wrong for the USA to defend itself/strike out against possible future enemy attacks? That's a whole different question in my mind. Perhaps you need help in rewording your questions?
