Bergdahl came off sounding like a stupid little ****. Basically said he ran off to "prove he could do some Jason Bourne stuff" and "didn't like the way leadership was doing things." It's pretty cut and dry desertion.
Then he "gets caught" by the bad guys trying to sneak back to his outpost. We lost several soldiers trying to find his dumb ***, and then POTUS trades a bunch of bad guys from Gitmo for this little ****.
