And I dont recall hearing that any of the 600 or so US POWs in Vietnam just walked away from their duty stations and sought out the Viet Cong. I think there might have been one such case during the decade long US involvment where a few million US troops served (Garwood).
No comparison between the release of Vietnam POWs and the trading of five top level terrorists for the deserter Bergdahl.
Bingo! Regardless of how you may feel about McCain as a senator, no one should disparage him for what he went through as a P.O.W. He did not walk away from his post and seek out the Viet Cong - he was captured. He endured years of brutal treatment at the hands of his captors, and never collaborated with the enemy. Who the hell does Candy Crowley think she is?
