I will admit I know nothing about the handling of POW's (which is what the military is calling Bergdahl), so I don't know whether this is standard operating procedure or not. But given the way his condition was being described shortly after his return, this seems a rather remarkable emotional/mental recovery.
We were getting descriptions of Bergdahl being detached from reality. These seemed to be put out there in an effort to push back on calls for investigating Bergdahl as a deserter. Now he's ready for active duty?
