Parents stymied. Dude got raised by lib parents. Bought into it because it's the easy way to go. Was gonna change the Army from the inside, or was going to be a superhero and sit down with those Talis and they'd see that Americans were just regular Jhokars just them and peace would break out. Either way, his folks fed him the "you're going to be great and special".
Didn't work that way, tho. I imagine he probably endured some pretty horrific shit. And he grew to realize that all the "everyone's the same as everyone else" that his daddy fed him was bullshit. And I'm sure his hosts showed him every time daddy kissed the ass of some Muslim terror group. I imagine maybe, at some point, he blamed his parents and their training of him for putting in the position of being ass pounded by the holy warriors. I imagine he grew to hate his parents.
Nothing to back this up. Just thinking out loud..
