Issue No. 9 | Monday, June 15, 2026
Good morning,
Welcome to The Science Diplomat Playbook, your Monday morning guide to what’s shaping the week ahead in global science diplomacy.
The lead
From nuclear verification to military AI, governments are relying on scientific expertise, inspections and monitoring to manage political disputes.
As G7 leaders gather in Évian-les-Bains, attention is focused on a newly announced U.S.-Iran framework agreement that could reduce tensions over Iran's nuclear program and reopen the Strait of Hormuz. U.N. Secretary-General António Guterres welcomed the agreement on Sunday as "a critical step towards the peaceful settlement of the conflict." While many details remain unresolved, diplomats, inspectors and nuclear experts are assessing the implications of last week's International Atomic Energy Agency Board of Governors meeting in Vienna, where safeguards, verification and Iran's nuclear material were among the central issues under discussion.
The emerging agreement leaves unresolved some of the most difficult questions surrounding Iran's nuclear activities. Any lasting arrangement would depend heavily on verification, monitoring and access arrangements capable of establishing confidence among governments that remain deeply divided on the issue.
In Geneva, governments, military officials and technical experts are meeting under U.N. auspices to discuss artificial intelligence in the military domain. The informal exchanges, convened by the U.N. Office for Disarmament Affairs, are part of a General Assembly process examining how military AI should be governed before new technologies outpace existing rules and institutions.
The week’s agenda points to a recurring feature of international affairs: political agreements often depend on institutions capable of establishing facts, monitoring compliance and evaluating technical claims.
Inside institutions
International Atomic Energy Agency — Verification after Vienna
The IAEA Board of Governors concluded its June meeting on Friday after discussions on Iran, Syria, North Korea, Ukraine and AUKUS. The emerging U.S.-Iran framework places renewed attention on verification, monitoring and inspector access, areas where the Agency would be expected to play a central role should negotiations progress toward a broader nuclear agreement.
United Nations Office for Disarmament Affairs — Military AI enters a new phase
Governments convene in Geneva for three days of informal exchanges on artificial intelligence in the military domain and its implications for international peace and security. Mandated by the General Assembly, the discussions are intended to clarify concepts, identify areas of convergence and inform future negotiations on military AI and autonomous weapons systems.
The exchanges take place alongside broader international efforts to establish rules and norms for military AI, including ongoing discussions under the Convention on Certain Conventional Weapons on lethal autonomous weapons systems.
World Health Organization — Ebola preparedness and response
WHO continues coordinating the international response to the Ebola outbreak affecting Congo and Uganda, including implementation of the joint WHO–Africa CDC response plan.
United Nations Human Rights Council — Twenty years after reform
The Human Rights Council opens a new session in Geneva as the U.N.’s principal human rights body marks two decades since replacing the former Commission on Human Rights in 2006. The anniversary comes amid continued debate over accountability, state sovereignty and the effectiveness of international human rights mechanisms.
Security Council watch
Colombia continues its presidency of the United Nations Security Council with a focus on mediation, dialogue and conflict prevention.
Council members are expected to follow developments related to Iran, Ukraine, Lebanon and maritime security in the Strait of Hormuz. The Council will also receive a briefing on Yemen, where regional security dynamics intersect with broader discussions surrounding Iran and maritime stability.
On June 17, the Council will hold an open debate on women, peace and security under the theme “Peace is Decided with Women: Emerging from Conflict by Enhancing Their Participation.”
As the secretary-general race gathers momentum, questions of nuclear verification remain at the center of international diplomacy. Following last week's candidates' debate in Geneva and Monday's General Assembly dialogue with María Fernanda Espinosa, contenders are entering a period of greater public scrutiny as they seek to distinguish their visions for the future of the United Nations.
Across regions
G7 Summit — Diplomacy under pressure
Leaders of the Group of Seven meet in Évian-les-Bains amid discussions surrounding Iran, energy security, Ukraine, artificial intelligence and global economic stability. Any movement toward a U.S.-Iran understanding is likely to shape conversations throughout the summit.
Climate diplomacy — Bonn enters its final week
Negotiators continue work at the Bonn climate meetings ahead of COP31 in Antalya. Discussions on adaptation, implementation and the future direction of the climate regime are expected to intensify as delegates move toward the conclusion of the session.
Europe — Science diplomacy examines itself
Researchers, practitioners and policymakers gather in Aarhus for a conference on the future of science diplomacy, with sessions addressing geopolitics, research security, public engagement, space governance and international scientific cooperation. The meeting reflects a broader debate about how the field is adapting to technological change, geopolitical competition and shifting patterns of global cooperation.
Signals
• Verification remains central to efforts to manage nuclear risks and sustain diplomatic agreements.
• Military AI moves from expert discussions into formal multilateral processes.
• Technical institutions are central to how governments manage disputes involving security, technology and global risks.
