The sense of purpose helps, but there may also be neurobiological effects of interacting with an animal; research has shown that when focus is on petting and playing with a dog, it can increase oxytocin, a brain chemical that boosts trust and quiets the brain's fear response.

I don't know if the veterans were actually drinking. Maybe they just wanted a late-night place to gather, have a pricey cola, shoot the bull, and give each other support.

Personally, I can't think of a single group in the US more "entitled" to deference versus having their motives judged as something more sinister.
