This guy absolutely nails it.
He certainly does. Put another way, just before WWII:......."People sleep peaceably in their beds at night only because rough men stand ready to do violence on their behalf." - George Orwell.
It's not that the "ready rough men" are any rougher, it is that those who peaceably sleep, work, study, have become softer.
You, sir, have nailed it. The protected are soft, because the protectors are rock hard.
