>These aspects of the nuclear security system were designed by politicians, This is false. I suggest reading Command and Control; it is illuminating and terrifying. The setup you described evolved from a tug of war between competing bureaucratic interests combined with ineffective oversight. The various military organizations fought to keep control and funding of prestigious nuclear weapons; the political arm dealt with the paradox inherent in having a system that was ready to be deployed at a moment's notice, but impossible to detonate accidentally. The compromise that emerged were these broken systems. To quote from Command and Control: >After the accident at Thule, the Pentagon had ordered SAC [Strategic Air Command] to impose some form of use control. Instead of relying on PALs, during the early 1970s the Air Force put a coded switch in the cockpit of every bomber that carried nuclear weapons. The switch permitted an arming signal to be sent to the bomb bay when the right code was entered. The lock had been placed on the bomber, not inside the bombs—and a stolen weapon could still be detonated with a simple DC signal. SAC was far more worried about its weapons being rendered inoperable during wartime than about someone stealing them or using them without proper authorization. During the late 1970s, a coded switch was finally placed in the control center of every SAC ballistic missile. It unlocked the missile, not the warhead. And as a final act of defiance, SAC demonstrated the importance of code management to the usefulness of any coded switch. The combination necessary to launch the missiles was the same at every Minuteman site: 00000000.
