Yes, the Bush-Obama era anti-war movies are clumsy attempts to take up the same theme that don’t work because they’re trying to apply lessons drawn from WWI-horror to radically different situations with no regard for the facts of either set of situations. That’s simply dishonesty; it doesn’t invalidate the underlying concept they’re trying to exploit.

The existence of heroism at Verdun does not change the fact that, for the men who lived through it, the thing called “war” had to be avoided at absolutely and literally any cost, to the point that twenty years later they were terrified and horrified at the mere suggestion. How and why that opinion gets formed — especially among the people who supposedly won — is absolutely a story worth telling, and the lesson being communicated is one worth learning, regardless of how the dishonest may attempt to twist it to serve their own ambitions.
