No, the concern was that a deranged officer might launch on their own, without correct authorization and checks from another person. This resulted in the two-man rule.

When I did maintenance on our comm systems in certain areas of the base, there was always someone else with me. Entering alone meant that you would get shot (signs were up saying lethal force was authorized, and they meant it). What's more, our workcenter was divided into teams and members of each team would not be allowed to maintain equipment from the other, to prevent a single person from making unauthorized modifications to both.

Two-man was taken quite seriously.
