And what should we do with such people if we have no wars where we can direct their activities to?

Randomly start wars just to keep them occupied with something?

I'm pretty sure that those people are actually very rare and that most people that join the military do it because of patriotism and propaganda.

Most soldiers probably don't know what they will be facing and how it will affect them in a negative way, which would explain the high suicide rate.

In my experience the vast majority of people join the military for job opportunities and benefits. I know more military members than average I would say. My husband and many of my friends being active duty, my father, grandfather, some friends, and the majority of my uncles being vets.

The military doesn’t commit suicide at a significantly higher rate than the general population.
