How war has influenced ancient, classical and medieval societies

[Husar]

All this talk is weird. PTSD only occurs if the army goes to war if I'm not mistaken. If the army goes to war, people will also usually die in the war. In this case, the benefits of being in the army probably do not outweigh the downsides of having war, such as the cost of lives and possible destruction of stuff on either or both sides. When we just assume the army never goes to war anyway because we have reached such peaceful times (despite some of the rhetoric in the Ukraine thread), then having an army is probably the most expensive and ludicrous way to prevent suicides in the first place. And it's no surprise that brainwashing people and pretending to give them a useful purpose in life (and new friends) can remove their suicidal thoughts.
