The article is actually somehow worse than the headline. It looks at things on a scale of thousands of years, and the argument is essentially "war happened, the conditions of humanity improved, ergo war is good". Then it's just filler, mostly name dropping events and famous works, literally distracting you from the fact that it's a dog shit argument by going "oh you think my argument is dumb? Well I'm smart so how could that be?"
"What about all the good things war has done for us? Why don't we ever hear speeches about that? Jobs, technology, a common purpose... All we're sayin' is... GIVE WAR A CHANCE!"
-Literally a Metal Gear Rising villain.
