You know, I think I was in 5th grade when I heard about this (in the 70s). I remember thinking "no way, we'd never do that" and asking my mom about it. She said she learned about it in the 50s and had exactly the same reaction and asked her mother who said it was probably the most shameful thing the US had ever done.
I agree, we need to remember that in times of war and stress, America is capable of great things and terrible things. I hope we'll see the parallels and stand up for those that are less fortunate or different than ourselves.
