The global treaty-based nuclear order is running out of steam. The problems facing it are progressively building up, while problem-solving is losing momentum. The search for a “golden key” to address disarmament and non-proliferation in a way fit for the 21st century prompts decision-makers to look for novel approaches. NATO needs to actively shape this newly emerging space. Acting today from within a tight policy and institutional “corset”, the Alliance should strengthen its non-proliferation and disarmament portfolio, and harness its consultative and coordination strengths for agenda-setting, norm-shaping and awareness-raising within the international community.
