Political correctness. If you look at any number of comments sections, or a Trump speech, or listen to a lot of very angry people, you’ll hear the military’s failures being laid at the feet of political correctness.
Benjamin Franklin nailed it when he said, "Fatigue is the best pillow." True story, Benny. There's nothing like pushing your body so far past exhaustion that you'd willingly, even longingly, take a nap on a concrete slab.
And no one knows that better than military service members and we have the pictures to prove it.
