Facebook posts reveal Bowe Bergdahl's frustration

In Facebook posts written before he vanished from his Afghan military base, US army Sergeant Bowe Bergdahl spoke of his frustration with the world and his desire to change the status quo.

He criticised unnamed military commanders and government leaders and mused about whether it was the place of the artist, the soldier or the general to stop violence and "change the minds of fools".

In his personal writings, he seemed to focus his frustrations on himself and his struggle to maintain his mental stability.

The writings paint a portrait of a young man who was dealing with two conflicts - one fought with bullets and bombs outside his compound, the other fought within himself.

Bergdahl's Facebook page was found on Wednesday, and it was suspended by Facebook for a violation of its terms a short time later. Bergdahl opened the page under the name "Wandering Monk." His last post was made May 22, 2009, a few weeks before he was taken prisoner.

Bergdahl, the only U.S. soldier held captive in Afghanistan, was recently released after five years as a prisoner of the Taliban. In exchange, the US released five detainees from a detention centre in Guantanamo Bay, Cuba. The circumstances surrounding the swap and Bergdahl's capture in 2009 have raised a national debate, with Bergdahl's supporters and friends joyous at his rescue, and some members of Congress - and some of his own platoon - calling him a deserter.
