The movie tries to make a justification of war attrocities, the shooting of enemy prisoners (same logic could be applied equally to the shooting of American prisoners). Spielberg has to be the biggest weenie of them all. Like he wouldn't be the first one to turn tail and run in a battle. Naturally he tries to cover his own tracks with the war correspondent character who, of course, "comes to his senses" and shoots an enemy prisoner in the end to redeem his cowardly self. Moral of the story, you just have to kill an unarmed helpless soldier once in a while to get everyone else's attention. Great message!
Hell in the Pacific was a better movie.
