Yes, it surprises and shocks me. Perhaps it's the era I grew up in. All through elementary school and up through high school we heard about how safe it was, that no one person could control it, that it took special codes and there was a guy with a briefcase on his wrist (I mean literally, handcuffed to his wrist) with the Secret Nuclear Codes who followed the president wherever he went. I mean it was just drilled into our heads how many safety redundancies were built into the system. And now we learn nuclear weapons were codeless, and guarded by a lone US armed soldier? Jesus. Yes it's shocking.
