Sitting here with 2021 hindsight and being fairly well read on WWII, the pre- and post- times around it, I agree that what FDR did was wrong. But I cannot issue an absolute condemnation on it, although I despise that bastard with regards to what he started in this country with regards to the New Deal.
In 1941, the bulk of the Pacific Fleet was at the bottom of Pearl Harbor, a tiny group of Hawaiians of Japanese descent or immigration did spy for Japan. Again, VERY few. People were not making rational decisions about some things and what was done to the Japanese Americans makes me grind my teeth. But I was not in their shoes and having to make those decisions.
I absolutely and unequivocally admire the Japanese-Americans. The 442nd Regimental Combat Team, many who were volunteers from the internment camps, was the most decorated unit in the US Army of WWII, seeing heavy combat in Italy against the Germans. Their nickname was "Some Americans from Hawaii" and their patriotism to this country in spite of their treatment cannot be questioned. At least in my presence.
