The systems devised to govern the use of nuclear weapons, like all complex technological systems, are inherently flawed. But the failure of a nuclear command-and-control system can have [serious] consequences. Millions of people, perhaps hundreds of millions, could be annihilated inadvertently. Today, the odds of a nuclear war being started by mistake are low - and yet the risk is growing, as the United States and Russia drift toward a new cold war. Many of the nuclear-weapon systems on both sides are aging and obsolete. The personnel who operate those systems often suffer from poor morale and poor training. In 2013, the two-star general in charge of the entire Minuteman [intercontinental ballistic missile] force was removed from duty after going on a drunken bender during a visit to Russia. The following year, almost a hundred Minuteman launch officers were disciplined for cheating on their proficiency exams. In 2015 ... a launch officer at Minot Air Force Base, in North Dakota, was sentenced to twenty-five years in prison for heading a violent street gang. As the job title implies, launch officers are entrusted with the keys for launching intercontinental ballistic missiles. The Minuteman III is a relic of the Cold War not only in design but also in its strategic purpose. When the atomic bomb was being developed ... the destruction of cities and the deliberate targeting of civilians was just another military tactic. The Geneva Conventions later classified those practices as war crimes - and yet nuclear weapons have no other real use.
