Today I found out that during the height of the Cold War, the US military put such an emphasis on a rapid response to an attack on American soil, that to minimize any foreseeable delay in launching a nuclear missile, for nearly two decades they intentionally set the launch codes at every silo in the US to 8 zeroes.
I guess the first thing we need to address is how this even came to be in the first place. Well, in 1962 JFK signed the National Security Action Memorandum 160, which was supposed to ensure that every nuclear weapon the US had be fitted with a Permissive Action Link (PAL), basically a small device that ensured that the missile could only be launched with the right code and with the right authority.
There was particularly a concern that the nuclear missiles the United States had stationed in other countries, some of which had somewhat unstable leadership, could potentially be seized by those governments and launched. With the PAL system, this became much less of a problem.
Beyond foreign seizure, there was also simply the problem that many U.S. commanders had the ability to launch nukes under their control at any time. Just one commanding officer who wasn’t quite right in the head and World War III begins. As U.S. General Horace M. Wade stated about General Thomas Power:
I used to worry about General Power. I used to worry that General Power was not stable. I used to worry about the fact that he had control over so many weapons and weapon systems and could, under certain conditions, launch the force. Back in the days before we had real positive control [i.e., PAL locks], SAC had the power to do a lot of things, and it was in his hands, and he knew it.
