This is a phenomenal movie, was just thinking about possible similar themes.
"The Last Mujaheddin". It's the story of an American military adviser sent to Afghanistan, circa 2002. He is sent to train the newly formed Afghan army, train them in the ways of modern warfare to crush the last remnants of the overthrown Taliban forces, the savage backwards indigenous peoples clinging to their old ways who must be annihilated so that the new government may flourish. The soldiers he is to train are unmotivated to learn American methods, but by gosh he's going to try. This new army is pressed into battle against the Taliban too soon and is routed, our protagonist captured and taken as prisoner by these Taliban deep in the mountains. While there he observes their ancient ways, their purity of purpose, their uncorrupted ideals, their devotion to one another. He understands the practicality and necessity of their ways - how they treat women, why they fight, and recognizes how corrupt and shallow the enemy is. He begins to sympathize with them, he comes to identify with them. In the end he fights with the Taliban, and is the last survivor of an epic final battle. In the end he is: The Last Mujaheddin.
You can't make this movie until at least 2050, when all of these wars are long past, when the taliban are nothing but an obscure memory.
Same thing really, I imagine that the Japanese government in this movie (however historically accurate) sees see the samurai that way - terrorists, backward ways, hindrance to progress.
What else?
