American news media portrays Sgt. Bowe Bergdahl and his apparent decision to simply walk away from the war in Afghanistan as bizarre and incomprehensible.

I wonder why it doesn't happen all the time.

From The New York Times:

"Sometime after midnight on June 30, 2009, Pfc. Bowe Bergdahl left behind a note in his tent saying he had become disillusioned with the Army, did not support the American mission in Afghanistan and was leaving to start a new life. He slipped off the remote military outpost in Paktika Province on the border with Pakistan and took with him a soft backpack, water, knives, a notebook and writing materials, but left behind his body armor and weapons — startling, given the hostile environment around his outpost."

There's little doubt. Bergdahl was politicized by what he saw.
