CNN’s Candy Crowley asked John McCain this morning whether trading top Taliban leaders from Guantanamo Bay for Sergeant Bowe Bergdahl was better than having to release the detainees when U.S. combat operations end in Afghanistan. McCain thinks that’s a false choice: Men like the the five commanders released, he believes, should be tried if possible, but just held indefinitely otherwise.

When pressed as to what authority or what assurances he’d trust to keep the five detainees from returning to terrorism, McCain simply said, “well, first of all, I wouldn’t have released them.”
