Not sure how you can read that and not see the point
He's not even saying the war was worth, or even not worth, fighting.
The article really isn't about war . It's about the American psyche and how we have reached a point in our collective where we accept no pain, our threshold is almost zero. That our actions are no longer measured against history (where they might show well), but rather measured against perfection.
I thought it was a great article.
