Yawn.<p>The W177's were secured with bike locks ... inside a reinforced concrete bunker surrounded by razor wire and patrolled by armed guards with orders to use lethal force to stop anyone trying to gain access to them without proper authorization.<p>Just like the USSR's land-based ICBMs didn't have PAL codes -- instead they were guarded by a platoon of KGB troops who didn't know how to launch the missile, but sure knew how to stop the strategic rocket forces' crew from launching the missile without orders.<p>Folks on HN are predisposed to thinking about automating security procedurally, but seem to miss the point that military organizations have been automating security through process carried out by human bodies for centuries, if not millenia; all they need is enough obedient soldiers with guns and orders not to allow [X] to happen without authorization [Y] or their ass is on the line to ensure that the bombs are <i>de facto</i> secure.
