I recorded two podcasts while at the U.S. Army War College. The second was on Lethality. In DoD terms, lethality means "good." It's the new hotness--all the rage. As an artilleryman, I approve.
But there's another side to these things. I've also studied a lot of economics, and it may just be easier to lose the peace as to lose the war. In that vein, I offer There's More to Life than Lethality. (Though the Space Force #pewpew article was more fun.)
