Grading Progress on 13 Steps Toward Nuclear Disarmament
All NPT states agreed in 2000 to lay out a practical path toward nuclear disarmament – the 13 Steps. While some steps toward disarmament have been taken, much more needs to be done.

All NPT states agreed in 2000 to lay out a practical path toward nuclear disarmament—the 13 Steps. Are these still the right steps? How far have we come? Sharon Squassoni assesses the progress of the declared nuclear-weapon states (United States, Russia, China, France, and the United Kingdom) on the steps, and recommends measures to breathe new life into the 13 Steps or a similar package.
Recommendations:
- The 13 Steps are still the currency of the nuclear bargain, but need updating. New approaches, like Japan's "11 Benchmarks for Global Nuclear Disarmament" deserve attention.
- U.S. leadership is critical, but not enough. Other states, nuclear-weapon states and non-nuclear weapon states, must do their part.
- Recent Russian initiatives are helpful, but nuclear weapons deserve less, rather than more emphasis in their security policies.
- India, Israel, and Pakistan – all weapon states outside the NPT – must be included in the disarmament dialogue.
