Listen to (or read) the words of Tom Hanks in regards to his view of the U.S. and WWII. Then, ask yourself, would he allow his view to influence how Band of Brothers was directed.
We fought the war with a segregated military. Only a few black soldiers were permitted to see combat.
We interned in camps West Coast Japanese-Americans but did not intern German or Italian-Americans. We restricted Japanese-American troops to the European theater.
Although you can identify logical reasons for both the fact is we used nukes and flamethrowers against the Japanese.
That is not to throw bricks at our folks. It was a different era. It was a tough, brutal war in the Pacific, IMHO primarily because of Japanese war crimes and abuse of prisoners. Our vets deserve all honors we can give them.
I'm just saying Hanks isn't out in liberal la-la land by pointing out that this history is like most other not a black and white narrative, the saints we have canonized weren't always saints all the time and the demons we have demonized weren't all bad all the time. That's history.
