Yeah, I'm not generally anti-military, but there are two major problems with our military system that ensure I'll always try to talk young people out of joining.
The first is that we've been inventing/starting proxy wars that we eventually send our own troops into. Our military should only be entering wars when we're attacked.
The second is the rampant sexual-assault/rape problem our military has. As long as the system refuses to weed out and remove offenders, I'll never say it's a good idea for anyone to join.
