No I have never been court martialed. I am Not an a Asshole
Your reading comprehension is off, just a bit: never said that you were court-martialed. Merely said that I have been a member of several court-martial Boards (one of the judges), have referred several of my Marines to various courts-martial, and have been the primary witness at several courts-martial - and even was an assistant defense attorney for one. My background is more less usual for a career officer.
Therefore, it's just possible that I may know a whole lot more about those proceedings than you do.
I despise Bergdahl a lot more than you do, and if I had been on his board, he'd be standing in front of a firing squad at Leavenworth. But neither President Trump nor Congress had anything to do with Bergdahl's sentence. That was the responsibility of that army General Court-Martial Board and for whatever reason, they failed to do their duty.
