With an all volunteer force that's about what it boils down to. Of course the common soldiers don't start the wars, but they're the ones that have to pay for them.
Finding yourself? Actually not a bad thing. After 22 years in the suck I realized that every good thing in my life traced back to the day that I signed my name on the dotted line and took the oath. Nope, it doesn't work out that way for everyone, but for the majority, yeah, it's a "great place to start". I've got a ton of friends that I call brothers, had some hella good times all around the world, earned my bachelors degree with no student debt, so I've got that goin' for me, which is nice.
