The series of zeros wouldn't have been enough to launch the missles. There were switches and keys and whatever that had to be thrown in the proper order. It wouldn't be something where you bumped into the desk and accidentally nuked Vladivostok. But this did mean that if a base was overrun by hostiles or a missle crew went wacky they could make a deliberate action and launch without the proper authorization. I guess the military figured their security and training was sufficent to prevent this. Pretty scary, I agree.
