Many complain on negativism in HN comments, but how in the world can a sane person express anything positive when there's a hell-bent will in conjunction with the "next war"?
I consider myself an optimist, but given that the US has been in 229 wars over it's 249 years since founding, it seems highly unlikely that there wouldn't be a "next war".
Your concern is reasonable but misdirected. This article is a publication of the "Modern War Institute", a research organization at West Point, the US Army military academy; it is literally their job to anticipate and plan for the next war, whatever it may happen to be. Deciding whether those plans ought to be used is a completely different responsibility.
Comparing the negativity of HN to the inevitability IRL warfare is absolutely hilarious, but I take your point
Ukraine didn't want to go to war, but someone else made that choice for them.
Are you under the impression that humanity could reach a state where there is never another major war?
I don't know how one would reach that conclusion, least of all a Major at the nation's leading military educational institute. Nothing "hell-bent" about it.
