What we did to respond to the Japanese atrocities was what we had to do to stop them. Most estimates are that we saved millions of lives (Japanese and Allies) by dropping the bombs and avoiding a protracted invasion of Japan.

As for internment, it's hard to believe that that squishy liberal Roosevelt, the progressives' hero, did such a dastardly thing (I'm speaking of internment). I guess he was a 'country first' kind of guy also. While people were interned they were not tortured or starved. Even the Japanese prisoners that we took during the war were treated humanely. Unlike the American prisoners taken by the Japanese.
