Understanding the International Atomic Energy Agency’s mandate, structure, and its critical role in today’s nuclear diplomacy.
As of mid-2025, international focus has once again turned sharply to nuclear diplomacy—especially concerning Iran’s nuclear program. Following recent airstrikes by the U.S. and Israel on Iranian nuclear facilities in June, Iran has suspended cooperation with the International Atomic Energy Agency (IAEA), obstructing inspections and verification missions. In response, the E3 nations (France, Germany, and the UK) initiated urgent nuclear talks with Iran in Istanbul in July 2025. This marks a critical juncture, as the expiration of key U.N. sanctions under the 2015 Joint Comprehensive Plan of Action (JCPOA) approaches in October.
The IAEA, which had previously declared Iran non-compliant with its safeguards obligations, now finds itself blocked from accessing sensitive sites, making independent verification of Iran’s nuclear activity increasingly difficult. With over 400 kg of uranium enriched up to 60% reportedly unaccounted for, concerns about Iran nearing weapons-grade capability have escalated dramatically.
Amid these tensions, the importance of the IAEA as an independent, technical, and multilateral watchdog has never been clearer. Understanding the IAEA’s origins, functions, and its vital role in preventing nuclear proliferation offers crucial insight into today’s geopolitical landscape.

The International Atomic Energy Agency (IAEA), established in 1957 and headquartered in Vienna, Austria, is the world’s central intergovernmental forum for scientific and technical cooperation in the nuclear field.
Its primary mission is to promote the safe, secure, and peaceful use of nuclear science and technology, contributing both to international peace and security and to the achievement of the United Nations’ Sustainable Development Goals (SDGs).
Origins and Foundational Vision of IAEA
The origins of the IAEA trace back to a pivotal moment in world history. In the wake of World War II and the dawn of the nuclear age, the world faced both deep fears and high expectations about the potential of nuclear energy. It was in this context that U.S. President Dwight D. Eisenhower, in his famous "Atoms for Peace" speech to the United Nations General Assembly on 8 December 1953, proposed the creation of an international organization to monitor and manage the use of nuclear technology. This initiative laid the groundwork for what would become the IAEA.
After discussions among representatives of more than 80 countries, the IAEA Statute was drafted and adopted in October 1956, and officially came into force on 29 July 1957. The Agency was envisioned to ensure that nuclear assistance and technology would be used only for peaceful purposes, not military ones.
Core Mandate and Legal Framework
As an autonomous intergovernmental organization, the IAEA’s responsibilities include increasing the contribution of atomic energy to global peace and well-being, while ensuring that it is not misused for military purposes. A key mechanism for this is the implementation of IAEA safeguards—legally binding verification systems that allow the Agency to independently confirm a state's compliance with its nuclear non-proliferation obligations.
Safeguards are technical measures applied by the IAEA to verify that nuclear material is not diverted from peaceful uses to nuclear weapons or other nuclear explosive devices.
These safeguards are enshrined in legally binding agreements with member states, particularly those that are party to the Treaty on the Non-Proliferation of Nuclear Weapons (NPT), which entered into force in 1970. Under this treaty, all non-nuclear weapon states are obligated to negotiate and maintain safeguards agreements with the IAEA, thereby allowing the agency to monitor nuclear facilities and inspect nuclear programs.
Role in Non-Proliferation and Verification
The IAEA plays a central role in preventing the spread of nuclear weapons, often referred to as nuclear proliferation. Through its technical monitoring and on-site inspections, the agency provides assurance that nuclear energy programs remain peaceful.
For instance, the IAEA was the first organization to uncover evidence of North Korea’s nuclear weapons program. Conversely, during the lead-up to the Iraq War in 2003, the IAEA disagreed with claims by the U.S. regarding Iraq’s nuclear activities—claims that were later shown to be inaccurate, thus affirming the IAEA’s credibility and independence.
In recognition of its critical work, the Norwegian Nobel Committee awarded the Nobel Peace Prize in 2005 to the IAEA and its then Director General, Mohamed ElBaradei (who served from 1997 to 2009). The award citation praised their joint efforts "to prevent nuclear energy from being used for military purposes and to ensure that nuclear energy for peaceful purposes is used in the safest possible way."
The Nobel Peace Prize is awarded to individuals or organizations that have made significant contributions to peace efforts, including disarmament and diplomacy.
As of now, the IAEA had 180 member states, making it a truly global organization. The IAEA operates through several key bodies:
The General Conference, comprising all member states, meets annually to set general policies, approve the budget, and elect the Director General.
The Board of Governors, consisting of 35 members, meets approximately five times a year and is responsible for approving safeguards agreements, policy implementation, and making recommendations to the General Conference.
The Secretariat, led by the Director General and supported by six deputies, manages the day-to-day work of the IAEA. It includes departments covering nuclear energy, nuclear safety, nuclear sciences and applications, safeguards, and technical cooperation.

Peaceful Applications of Nuclear Technology
Beyond non-proliferation, the IAEA also plays a pivotal role in promoting peaceful applications of nuclear technology in areas such as:
Medicine: cancer treatment and diagnostic imaging (e.g., radiotherapy).
Agriculture: improving crop yield and pest control through radiation techniques.
Water resources: using isotopic techniques to monitor water contamination and manage resources.
Industry: enhancing industrial processes with radiation-based quality control and material testing.
In a time when nuclear risks are rising—from Iran’s uranium enrichment to geopolitical instability—the role of the IAEA is more vital than ever. It remains the cornerstone of global non-proliferation efforts, the technical voice of reason in diplomatic crises, and a catalyst for peaceful scientific progress. As debates unfold about future sanctions, compliance, and global nuclear governance, the IAEA stands at the center of efforts to balance nuclear potential with responsibility.
