This discussion paper by Tanya Ogilvie-White, as part of UNIDIR’s Disarmament, Deterrence, and Strategic Arms Control Dialogue, highlights some of the key commonalities and differences across the many perspectives on nuclear deterrence. It also draws attention to significant knowledge gaps and uncertainties about this security paradigm. Doing so can help the process of identifying shared interests between nuclear deterrers and disarmers and assist in the urgent task of recrafting strategic arms control.
