Opinion noted. Who said it was about being tough? It may be germane to mention that our Armed Forces have been used for a long time as 'punishment' for unruly and/or selfish kids, or those who can opt for prison after certain transgressions. Still is. I know quite a few fuck ups that got a Marine Corps/Army "re-alignment" in their earlier years, and for the most part they are all now mature non-assholes.
If you read into Trump's time as a military cadet, I think you will find he did appreciate the concept of chain of command, he reveled in the masculinity of military-like duty. It meshed well with his bully personality. Also germane to my post is that I'm referring to the Trump of 50 years ago, not the imperious dipshit and coward we see today. Once his father was gone, he cranked the dipshit to 11.
