“Maybe Obama realized after the fact that Bergdahl was indeed a traitor and cost American lives.”
I would disagree with the “realized” word in that statement.
First, it was clear that Berg cost US lives from the outset.
Second, “traitor” is more a resume enhancement than demerit in the brain of 0bama.
Third, the one thing that 0bama has done, very hesitantly, very surreptitiously, almost never, is to admit he has erred. Sniveling little puke that he is, this way, by just overlooking the act of pardoning Bergdahl, he just dumps another meaningless nobody under the great voracious bus of his debris trail instead of maybe missing a round of golf due to timewasting, irritating paperwork.
Perhaps because the POTUS has much more limited authority to grant pardons where the defendant is under military (vs civilian- criminal) jurisdiction. (I don’t know the correct answer but I’d suspect that is the case)
I’m frankly surprised he did not pardon Bergdahl. That would have a nice sharp stick to shove in the eye of those who feel patriotic towards the military.
