The POW response is a punchline. McCain is the joke.

While McCain’s experience was wasted on the creepy troll, did it create a worldview incapable of anticipating the limits to U.S. military power in Iraq? Did he fail to absorb the lessons of Vietnam, so that he is doomed to always want to refight it? Did his captivity inform a search-and-destroy, shoot-first-ask-questions-later, “We are all Georgians,” mentality?
