I have said for awhile that I would not blame a single soldier for going full Ed Harris from the "The Rock". Our government has fucked over soldiers for as long as I have been alive.
Literally?
You stop caring.
You find yourself amazed that your past self thought they'd actually honor their agreements and bargains when you watch Congress talk about how they didn't approve the enlistment contract so the US government is in no way shape or form obligated to uphold those agreements.
You watch illegal immigrants get gibs and bennies while you wait 10+ years for your claim to be denied.
You watch fat LOLcows get SSI while you're working your broken body at shit jobs.
You find out your military education doesn't transfer to college or to work experience or licensing.
You watch as officers and the politically connected talk about how good it is to be a vet while you're wondering just what the fuck you were thinking.
Eventually, you go numb, and you quit caring.
There's a lot more, but you just stop caring.
Then, when your son, nephew, cousin, friend's kid asks if they should join the military, you tell them "Only if you like non-consentual anal sex for the rest of your life" and promise to shoot them in the shin if they get drafted.
Of course, then you get vets like the author of Terminal Lance saying that the only vets who are disillusioned are REMFs and fuckups and failures who didn't get slathered in pussy.
