Sgt. Bowe Bergdahl still has not spoken with his family since being released from Taliban captivity six weeks ago, the Wall Street Journal reported.

The announcement that the U.S. government had secured Bergdahl's release and that it was freeing five senior Taliban figures from Guantanamo Bay has been portrayed first and foremost as a prisoner exchange. But the four-year history of secret dialogue that led to Saturday's release suggests that the main goal of each side may have been far more sweeping.

From the Wall Street Journal:

Sgt. Bergdahl has refused to see his parents or speak to them on the phone, [an Army] official said. The decision by Sgt. Bergdahl, who returned to regular duty on Monday, suggests a deeper estrangement between the soldier and his parents than the military understood when he was released. Still, officials said, they don’t know the precise cause of the tension or when it began.

Bergdahl finished his formal counseling treatment at an Army hospital and began a new job Monday at U.S. Army North at Joint Base San Antonio-Fort Sam Houston in Texas.

Sgt. Bergdahl’s father, Robert Bergdahl, was an outspoken — if sometimes disturbing — advocate for his son throughout his five years of captivity.

The circumstances of Bergdahl’s capture in Afghanistan are the subject of a military investigation. Bergdahl was freed in a controversial deal in exchange for the release of five Guantanamo Bay detainees.
