So, your theory is that Bergdahl walked off the base to join the Boy Scouts? The Red Crescent? The Michael Jackson Fan Club, Jalalabad Chapter? Which of those stories would be consistent with Bergdahl's own words? To borrow from Rudeguy's post (which you ignored):
mom, dad
The future is too good to waste on lies. And life is way too short to care for the damnation of others, as well as to spend it helping fools with their ideas that are wrong. I have seen their ideas and I am ashamed to even be american. The horror of the self-righteous arrogance that they thrive in. It is all revolting. [...] [Three good sergeants had been forced to move to another company] [...] and one of the biggest shit bags is being put in charge of the team. [...] [My battalion commander was] a conceited old fool. [...] In the US army you are cut down for being honest... but if you are a conceited brown nosing shit bag you will be allowed to do what ever you want, and you will be handed your higher rank... The system is wrong. I am ashamed to be an american. And the title of US soldier is just the lie of fools. ... The US army is the biggest joke the world has to laugh at. It is the army of liars, backstabbers, fools, and bullies. The few good SGTs are getting out as soon as they can, [...] I am sorry for everything here. These people need help, yet what they get is the most conceited country in the world telling them that they are nothing and that they are stupid, that they have no idea how to live... We don't even care when we hear each other talk about running their children down in the dirt streets with our armored trucks... We make fun of them in front of their faces, and laugh at them for not understanding we are insulting them [...] I am sorry for everything. The horror that is america is disgusting. There are a few more boxes coming to you guys. Feel free to open them, and use them.
Only a moron's moron would ignore such words or pretend they have no relevance to the likelihood that Bergdahl deserted TO the Taliban.
As far as the OP, that does not address Bergdahl's actions
for which he will be tried as reflecting on Obama at all. It reflects the Obama administration's actions concerning Bergdahl, the political maneuvering that team Obama was doing, using Bergdahl to shore up Obama's approval. That is all after the fact blundering; it has nothing to do with Bergdahl's guilt, or level of guilt. Those here who have served of course believe that Bergdahl is guilty of deserting, probably intentionally to the Taliban, and should have been left there. After all, if you believe that America is evil and disgusting, then the Taliban are by definition the good guys. Those here like me who never served may believe that Bergdahl is guilty of deserting, probably intentionally to the Taliban, and yet still believe that Obama did the right thing by bringing him home to be tried fairly and, if found guilty, possibly imprisoned here. But at least to people like me, without the visceral reaction that service brings, whether or not Bergdahl is guilty, and if so, of what charges, is not any reflection on Obama. It's not even any reflection on Obama's decision to trade five terrorist leaders for him. As far as the government is concerned, Bergdahl must be considered innocent until proven guilty in a court of law, or at least until it becomes clear beyond a shadow of a doubt (e.g. Bergdahl making pro-Taliban propaganda videos) that he intentionally deserted. Up until that point, I expect Obama to attempt to bring him home like any other serviceman or -woman, even those judged guilty in the court of public opinion. Even Obama's campaign to benefit politically from freeing Bergdahl isn't evil to my mind, just typical political maneuvering leavened with an unusually big side of stupid. It is this stupidity that Unokitty addresses. Had Obama merely left it at "no American serviceman deserves to be left in the Taliban's hands, regardless of his actions", then Unokitty probably wouldn't have even made this thread. By attempting to make this man a hero who served "with honor and distinction", Obama smeared every serviceman and -woman who DID serve with honor and distinction, which is the vast majority of them.
Sheesh, this really isn't that difficult. There's really no down side for Obama here as long as he stays out of it. If Bergdahl is convicted, well, everyone with at least two functioning brain cells already believes he's probably guilty, so nothing changes. Obama's already taken the political hit for trading for him, and a conviction shouldn't affect anyone's thinking. If Bergdahl is acquitted, then Obama at the very least looks no worse and to most people looks better. Only if Obama is seen meddling in the process will he take another hit to his approval.
