That's a question for filmmakers, not me. There are a few (Da 5 Bloods, Red Tails, and Glory leap to mind immediately, and the latter was given an honourable mention in my article). Also, in fairness, some of these films aren't all white (Apocalypse Now, for instance). But this article is simply focused on what are (in my view) the ten greatest war films, which aren't necessarily an ideal representation of all races.
