Verifying nuclear disarmament poses an unprecedented technical challenge. There can never be certainty that nuclear-armed States have not retained militarily significant stockpiles of fissile material. In the short term, to help prevent these uncertainties from becoming a roadblock in the future, these steps could, inter alia, (a) collect and archive information about fissile material production; (b) place information about fissile material production and holdings in the public domain; (c) be more transparent about civilian nuclear materials; and (d) implement the proposed Fissile Material Control Initiative. On their part, non-nuclear-weapon states could be prepared to recognize these as meaningful steps towards disarmament.
