The only way to completely eliminate nuclear risks is to eliminate nuclear weapons from the planet.
Globally, the overall inventory of nuclear weapons is declining, but the pace of reductions is slowing compared with the past 30 years.
Moreover, these reductions are happening only because the United States and Russia are still dismantling previously retired warheads.
The US only has a limited ability to destroy an incoming nuclear intercontinental ballistic missile, a study released last month by the American Physical Society concluded.
