Summary
The United Kingdom, France, and Germany have initiated the process to reinstate United Nations sanctions on Iran, citing violations of the 2015 nuclear agreement. This agreement, which involved major global powers, aimed to limit Iran’s nuclear development in exchange for sanction relief. However, following the United States’ withdrawal in 2018, Iran escalated uranium enrichment activities. The European nations’ decision comes ahead of the deal’s expiration on October 18, 2025, which would render the “snapback” clause inoperative. A 30-day review period is now underway, during which Iran must negotiate a new framework with the US to avoid sanctions. Iran has strongly opposed the move, threatening countermeasures. The International Atomic Energy Agency continues to oversee compliance amid rising tensions.
