Technically, yes. In order to arm the missiles.
But the launch command still needed to be issued from two separate locations.
There was a Dead Hand procedure in place where the launch could be initiated from a single location on a timer, but that timer could then be terminated from any other location should the launch be unauthorised.
Don't get me wrong, the 00000000 arming codes were still pretty crazy, but as I said in my previous comment, I think we're at much higher risk of a nuclear apocalypse via incompetence/bad actors than we'll ever be from a single bad-tempered head of state.
