A new convention that tries to ban nuclear weapons and make it illegal to possess or use them was opened for signature on Sept. 20.  But you would be forgiven if you hadn’t heard about it, since none of the countries that actually have nuclear weapons are likely to sign. Many nuclear experts are concerned about this treaty’s shortcomings, including in the area of inspections and verification, but also about the choice made by many signatories to put negotiation of the treaty above more pressing, and arguably more effective, approaches to advancing disarmament.

Indeed, all of the countries that negotiated the Treaty on the Prohibition of Nuclear Weapon have long been on record opposing the possession of nuclear weapons and are legally committed to not possessing these weapons themselves. So while the treaty will have no immediate impact, it is a clear expression by many countries that nuclear weapons states are not moving fast or earnestly enough to get rid of them, and that far too many are boosting their reliance on nuclear weapons.  And these countries are right. But while many of the signatories’ motives are to be respected, bringing together a group of like-minded countries to declare what they have already committed to does not materially advance the cause of disarmament. Those who negotiated the ban took on no new obligations or responsibilities for themselves in this global endeavor.

All countries should move away from a reliance on nuclear weapons and take steps to make that possible.  The United States, at least until recently, has championed that goal and put real effort, resources, and capabilities toward making nuclear weapons a smaller part of its defense plans.  Finding new ways to reaffirm that goal, the central idea behind the ban, is a step in the right direction.  Yet there is much more all states can and must do to show that they are serious about eliminating nuclear weapons.  It is easy to repeat previous commitments, but harder and less dramatic for states to take direct steps that require compromise, hard work, and financial and technical investments. States have to put money and political capital behind disarmament if we are to make needed progress in an increasingly dangerous world. Sadly, some of the ban advocates and signatories come up short.

Fortunately, there are things that can be done. If states truly want to help eliminate nuclear weapons, here are a few concrete steps they can take – steps that are more meaningful and address more urgent threats to the cause of global disarmament.
