Well, for one thing, I don't believe in censorship, or keeping anyone from making any kind of movie they want. I personally have liked quite a few of the above movies, but I am pointing out that in hollywood, if the director is from the left, the military is going to be portrayed poorly.
Communists and Nazis are different and competing types of socialist.
Jerry Bruckheimer, Mel Gibson and Clint eastwood tend to portray soldiers, from foriegn countries as well in a more positive light. The film makers on the left show them in a less positive light.
It doesn't even have to be a movie about soldiers, they manage to fit in the bad stereotype of soldiers in non-military films. In American Beauty, the killer is a homophobic, brutally abusive marine. In the HBO series, True Blood, the cook, a character not actually in the books, is a psychologically damaged Iraq war vet. Since it is no longer popular to target vietnam vets as the deranged nut, they have started moving into the area of Iraq war vets. Toby Macguires recent movie with Natalie Portman and Jake Gyllenhall is along those lines.
The Japanese were brutal and treated P.O.W.'s as well as civillians in occupied countries as bad if not worse than the Germans and the Russians. The Rape of Nanking, their special medical units, the beheading contests, the torture and murder of captured soldiers and civillians is what I refer to with Clint eastwood trying to humanize the japanese soldiers. The things they did were policy, not rare events. I remember one text that talked about Japanese soldiers forcing marines to bury their comrades alive. So please, I know that their is a revision of the Pacific war about to take place, but until then, let's realize that the Japanese atrocities have yet to be fully addressed. In fact a couple of movies are coming out about Nanking or the other cities occupied by the japanese.
