Think of the loss of those that did die and what their contributions could have been to realize that this may seem clever but actually isn't. If Sam Clemens had died it would have been a loss, pure and simple. That people that die in wars end up not contributing to society may well mean that the next Einstein or Hawking was lost to humanity.
They weren’t even that subtle. If anything, the misinterpretations are illuminating about how being removed from realities of war distorts reasoning about it.
