With his second term now secure, it's time for Obama to come clean on Benghazi. If, in the unlikely scenario that the president wasn't briefed on the deadly assault, he needs to explain why, and tell us what consequences await those who failed him (and our servicemen). When something this serious fails to warrant any military support, the buck must stop with the commander in chief. Not the secretary of state, not an ambassador, not the CIA director, and not the Pentagon.
