"Go For Broke"
As with the film just cited on Sergeant York, it's not completely accurate (relatively few films are, even documentaries!) but does use a compelling figure (group, actually) from American history. It tells a bit of the story of the 442nd Regimental Combat Team. The 442nd Infantry/100th Battalion was a group composed of nearly all Japanese-American volunteer soldiers. They served with distinction in Europe, suffered a casualty rate of 314% (i.e. wounded/killed soldiers needed to be replaced more than three times over), and earned 18,000 individual decorations, including 21 Medals of Honor. They are recognized as the most highly decorated American military unit of their size. This was accomplished while many of their families were locked up in American prison camps, allegedly "for their own good".
It's kind of a corny old movie, but I'm glad the unit was given some recognition in the popular media.
By the way, I don't think this shows Asians are "better" or that the US is terrible. I think it points out how great America can be when it's citizens work their hardest to make their country a good, safe, free place to live. As always, thank you to all veterans! You've preserved freedom for over 200 years, and we can never thank you enough for your sacrifices.
