Against this backdrop, meaningful progress on\u00a0nuclear disarmament is unlikely<\/a>\u00a0in the\u00a0foreseeable future. Arms control negotiations have stalled, strategic trust between the major powers has\u00a0disappeared, and the security incentives that once enabled reductions in nuclear stockpiles have been replaced by intensifying geopolitical rivalry.\u00a0\u00a0This does not diminish the importance of arms control or non-proliferation. Both\u00a0remain\u00a0essential\u00a0long-term\u00a0objectives. But diplomacy must also adapt to strategic reality. At present, Western governments devote considerable diplomatic resources to managing arms control while comparatively little institutional attention is given to strengthening deterrence itself.\u00a0<\/p>\n This\u00a0imbalance should be corrected.\u00a0For example,\u00a0Australia,\u00a0Britain,\u00a0and the United States should\u00a0establish\u00a0dedicated Ambassadors for Strategic Deterrence who work alongside\u00a0and\u00a0not instead of\u00a0their ambassadors responsible for arms control,\u00a0non-proliferation,\u00a0and disarmament.\u00a0\u00a0\u00a0<\/p>\n Also, deterrence has evolved far beyond military capability. It now\u00a0depends on diplomacy, alliance management, strategic communications,\u00a0defense\u00a0industrial cooperation, technological integration<\/a>\u00a0and political credibility.\u00a0Maintaining\u00a0deterrence requires continuous engagement with allies and partners before crises\u00a0emerge, not simply military planning once they do.\u00a0A dedicated ambassador would provide strategic leadership across these issues. Rather than negotiating arms reduction agreements, their role would be to strengthen allied deterrence through diplomatic engagement, coordinate strategic messaging, deepen cooperation on emerging technologies,\u00a0facilitate\u00a0extended deterrence\u00a0consultations,\u00a0and develop stronger crisis-management mechanisms among partners.\u00a0<\/p>\n The Indo-Pacific illustrates why such a role has become necessary.\u00a0Unlike Europe, where NATO has spent decades\u00a0institutionalizing\u00a0nuclear consultation,\u00a0planning,\u00a0and deterrence,\u00a0the Indo-Pacific possesses no equivalent strategic architecture<\/a>\u00a0despite facing a more complex\u00a0nuclear environment. China, Russia and North Korea collectively present multiple nuclear challenges, yet America\u2019s regional alliances\u00a0remain\u00a0bilateral rather than integrated.\u00a0Australia,\u00a0Japan,\u00a0and South Korea each rely on extended United State for\u00a0nuclear deterrence, yet there is no permanent regional mechanism for coordinated nuclear consultations, shared deterrence\u00a0planning,\u00a0or collective strategic decision-making during a crisis.\u00a0<\/p>\n This institutional gap is becoming increasingly difficult to ignore.\u00a0A conflict over Taiwan, a major crisis on the Korean Peninsula,\u00a0or military escalation in the East China Sea would\u00a0almost certainly\u00a0involve multiple United States\u00a0allies simultaneously. Decisions regarding\u00a0escalation management, strategic communications and deterrence\u00a0signaling\u00a0could not realistically remain confined<\/a>\u00a0to separate bilateral relationships.\u00a0<\/p>\n \u00a0The Indo-Pacific therefore\u00a0requires\u00a0more than enhanced military cooperation. It requires stronger institutional arrangements for strategic deterrence.\u00a0Initially, this should take the form of\u00a0formalized\u00a0regional consultation mechanisms.\u00a0Regular strategic deterrence dialogues,\u00a0coordinated crisis planning, integrated intelligence assessments, shared escalation\u00a0frameworks\u00a0and agreed protocols for strategic communications would significantly improve allied preparedness.\u00a0<\/p>\n Over time, policymakers should also consider whether the Indo-Pacific\u00a0requires\u00a0its own form of\u00a0a\u00a0nuclear alliance.\u00a0Such an alliance need not replicate NATO, nor would it necessarily require the forward deployment of nuclear weapons throughout the region. However, NATO\u2019s experience\u00a0demonstrates\u00a0the value of\u00a0institutionalized\u00a0consultation, integrated\u00a0planning,\u00a0and political burden-sharing in\u00a0maintaining\u00a0credible deterrence.\u00a0<\/p>\n The region should therefore begin a serious discussion about whether elements of NATO\u2019s nuclear architecture,\u00a0which includes\u00a0structured consultation, coordinated planning and, potentially, future nuclear-sharing arrangements,\u00a0may become necessary as China\u2019s strategic capabilities continue to expand.\u00a0This debate will undoubtedly be controversial. Nuclear sharing\u00a0remains\u00a0politically sensitive, particularly for countries with longstanding commitments to non-proliferation. Yet strategic realities cannot be ignored simply because they are politically uncomfortable.\u00a0<\/p>\n Indeed, credible deterrence and non-proliferation have historically reinforced one another rather than existed in opposition. During the Cold War, NATO\u2019s nuclear-sharing arrangements strengthened alliance cohesion while helping discourage independent nuclear weapons programs among member states. Countries that\u00a0possess\u00a0confidence in extended deterrence are\u00a0less\u00a0likely to pursue their own nuclear arsenals.\u00a0A stronger Indo-Pacific deterrence architecture could achieve a similar outcome by reinforcing confidence in allied security guarantees while reducing incentives for further nuclear proliferation across the region.\u00a0This is precisely why diplomacy must evolve alongside military strategy.\u00a0Dedicated Ambassadors for Strategic Deterrence could lead these conversations internationally. They would engage regional partners, coordinate policy across allied governments, strengthen strategic messaging, develop crisis consultation\u00a0mechanisms\u00a0and help\u00a0shape an emerging deterrence architecture appropriate for twenty-first century<\/a>\u00a0security challenges.\u00a0<\/p>\n Dedicated Ambassadors\u00a0would also complement\u2014not replace\u2014existing ambassadors responsible for arms control and non-proliferation. Their missions would be different but mutually reinforcing.\u00a0One would continue pursuing the long-term objective of reducing\u00a0nuclear dangers through diplomacy.\u00a0The other would ensure that deterrence\u00a0remains\u00a0credible while those long-term conditions\u00a0remain\u00a0absent.\u00a0<\/p>\n The strategic environment no longer resembles that of the 1990s. It more closely resembles an era of prolonged competition among multiple nuclear powers, where deterrence has once again become the principal mechanism for preserving peace.\u00a0<\/p>\n Diplomatic institutions should reflect\u00a0the current conditions.\u00a0Creating Ambassadors for Strategic Deterrence would be a\u00a0modest\u00a0reform, but it would acknowledge an increasingly important\u00a0reality.\u00a0In today\u2019s strategic environment, deterrence is no longer solely a military function.\u00a0It is a diplomatic responsibility. If Australia,\u00a0Britain,\u00a0and the United States intend to preserve strategic stability in the Indo-Pacific, they will need diplomats whose primary mission is not simply reducing nuclear weapons, but preventing their use through credible,\u00a0coordinated,\u00a0and enduring deterrence.\u00a0<\/p>\n Natalie Treloar is an Australian Strategic Affairs Expert,\u00a0Indo-Pacific Security,\u00a0Defence\u00a0Policy & Nuclear Deterrence.
