Haven't seen any of these except Helen Mirren's Elizabeth, which I thought was absolutely excellent. I'm wondering a little about Clint Eastwood's handling of Flags of Our Fathers/Letters From Iwo Jima; he seems to have gone a bit PC in his old age, and I'm very much hoping he hasn't used the films as an occasion to bash the US - especially the utterly magnificent Marines of WWII's Pacific theater - and ennoble the Japanese in some sort of multi-culti New Age revisionist turnaround.
Flags doesn't seem to have any of that. The characters in the film don't understand how the Surabachi photograph made them heroes when you had an island full of real heroes doing heroic things day and night. Part of the film's messgae is that a nation needs heroes to help them focus their respect and thankfulness for a host of people they don't know and might not otherwise care about.
I've read some early comments from Japanese viewers of Letters and it does sound like there's some of what you fear going on. I read, for example, that a person described both American and Japanese combatants as "victims." "Victim" is an odd word to choose for either party but that's what was used. That could be a mis-translation or it could be genuine weasel-speak. I won't know till I see it.
