European Powers Pressure Iran on Nuclear Deal Violations
Three European powers, Britain, France, and Germany, have informed the U.N. Security Council of Iran’s violations of the 2015 nuclear deal. This move aims to pressure Tehran to address the issue diplomatically and avoid reimposing U.N. sanctions.
Background of the Nuclear Deal
The 2015 nuclear agreement, known as the Joint Comprehensive Plan of Action (JCPOA), involved the E3, China, Russia, and the United States. It limited Iran’s uranium enrichment to prevent the development of nuclear weapons. In return, sanctions from the U.S., U.N., and E.U. were eased. However, tensions escalated when then-U.S. President Donald Trump withdrew from the deal in 2018 and reimposed sanctions on Iran.
Recent Developments
The E3’s letter, dated June 3, references a recent U.N. nuclear watchdog report highlighting Iran’s violations, such as increasing its stockpile and production of high-enriched uranium. The letter did not threaten immediate sanctions but noted the expiration of the U.N. Security Council Resolution 2231 on October 18, 2025, which enshrined the JCPOA.
Iran responded by rejecting the European stance, arguing their nuclear expansion was justified after the U.S. withdrawal. “Iran’s decision to take remedial measures was in full accordance with its inherent right,” stated Iran’s U.N. ambassador.
Increasing Tensions
Tensions with Iran have heightened following the October 7 attack by Iranian-backed Hamas on Israel and other attacks by Iranian proxies on Western targets. Tehran has accelerated its nuclear program while limiting the International Atomic Energy Agency’s (IAEA) monitoring capabilities.
Diplomatic Efforts and Future Implications
Western diplomats suggest the E3 letter aims to increase pressure on Iran within the Security Council and allow time for a diplomatic solution before the 2025 expiry of the “snap back” power to reimpose U.N. sanctions.
Daryl Kimball, of the Arms Control Association, indicated the letter might lay the groundwork for potential future sanctions but emphasised the possibility of a diplomatic resolution. He warned that reimposing sanctions could lead to further escalation, possibly even Iran withdrawing from the nuclear Nonproliferation Treaty.
