E3 countries trigger UN sanctions against Iran's nuclear program
- E3 countries have triggered snapback sanctions against Iran due to non-compliance with nuclear deal.
- Iran's Foreign Ministry warned the sanctions would harm cooperation with nuclear inspectors.
- The situation presents challenges for international diplomacy in regulating Iran's nuclear activities.
On August 28, 2025, the United Kingdom, France, and Germany, collectively known as the E3, initiated the process to reimpose United Nations sanctions on Iran due to its escalating nuclear activities. This action follows a significant breach of the Joint Comprehensive Plan of Action (JCPoA), which was established in 2015 to regulate Iran's nuclear program in exchange for the lifting of sanctions. Since the withdrawal of the United States from the agreement in 2018, Tehran has taken steps that are seen as violations of the deal, leading to increased tensions between Iran and the E3 countries. The unlocking of the snapback mechanism, a provision included in the JCPoA, was viewed as a necessary step in light of Iran's lack of compliance and the growing concerns regarding its nuclear advancements. Iranian authorities condemned the sanctions’ reimposition, labeling it a provocation and warning of serious repercussions. The E3’s decision was described as difficult yet essential, as the Joint statement issued by the foreign ministers asserted that the sanctions are a protective measure for international peace and security, which is threatened by Iran’s nuclear program. Iran has been accused of building a stockpile of highly enriched uranium without any civilian justification, alarming the international community. There is a 30-day period during which Iran can attempt to negotiate a resolution before sanctions take effect, but the looming expiration of the snapback sanctions ability in October 2025 has spurred prompt action from the E3. They expressed their commitment to diplomatic engagement with Iran, urging the nation to address international concerns regarding its nuclear activities, though they remain cautious due to Iran's recent history of non-compliance. The situation remains fluid, with the potential for diplomatic talks to continue even amidst tensions. The E3 countries are hopeful for a resolution that would restore cooperative relations and mitigate the hazards regarding proliferation activities in Iran.
