Bottom Line Up Front
Senate Foreign Relations Committee Chairman Jim Risch (R-ID) is leading a letter to the Foreign Ministers of France, Germany, and the United Kingdom (E3) urging them to follow through with the snapback of United Nations sanctions on Iran. On August 28, the E3 initiated the snapback process under UN Security Council Resolution 2231, starting a 30-day process to reimpose all UN sanctions previously lifted under the failed and deeply flawed 2015 Iran nuclear deal (JCPOA).
This overdue action would restore critical international restrictions on Iran’s arms industry, missile program, and nuclear activities. The letter applauds the E3’s initiation of snapback, warns against any diplomatic backsliding, and encourages post-snapback cooperation to ensure coordinated enforcement.
FDD Action supports this letter and urges Senators to sign onto it.
Why It Matters
- Snapback of sanctions is already underway. On August 28, the E3 triggered the snapback mechanism under UN Security Council Resolution 2231, launching a 30-day process to restore all international sanctions previously lifted through the 2015 Iran nuclear deal (JCPOA). This marks a decisive step toward ending the JCPOA framework and holding Iran accountable for its nuclear extortion.
- A renewed sanctions regime will restore critical restrictions. Snapback will reinstate the UN conventional arms embargo, limitations on nuclear-capable delivery systems (including drones and missiles), as well as travel bans and asset freezes against senior Iranian terrorists and nuclear scientists. It will also prevent the scheduled expiration of international nuclear sanctions on October 18, 2025.
- Iran’s nuclear escalation requires a firm response. For years, Tehran has advanced its uranium enrichment, restricted International Atomic Energy Agency (IAEA) inspections, and supported terrorist proxies across the region. Even after successful U.S. and Israeli strikes on Iran’s nuclear infrastructure, the regime has doubled down on its commitment to restart its enrichment. Allowing sanctions to lapse would embolden the regime and undermine global nonproliferation efforts.
- Diplomatic delay plays into Tehran’s hands. For decades, Iran has used negotiations to stall accountability while advancing its nuclear and missile programs. In the latest example, Tehran has now reached a short-term agreement with the IAEA to resume inspections of its nuclear sites (something it was already expected to do outside of the JCPOA framework) but only on the condition that UN sanctions are not reimposed. This development underscores the importance of the letter’s call on the E3 to resist Tehran’s bids to slow down or dilute sanctions snapback, which would only reward Iran’s bad-faith tactics.
- Coordinated enforcement strengthens transatlantic security. The letter highlights opportunities for joint U.S.–European sanctions coordination, financial restrictions, and interdiction operations to ensure Iran cannot evade renewed UN obligations. A united front will maximize the effectiveness of snapback.
- Cutting off Iran’s financial lifelines is essential. Oil sales to China and illicit smuggling through third countries finance Iran’s nuclear and missile programs. The letter calls for stronger cooperation to block these revenue streams and close the regime’s banking sector abroad, particularly in Europe.
- Maintaining pressure safeguards U.S. and allied interests. Reimposing and enforcing international sanctions constrains Iran’s malign activities, supports Israel and regional partners facing Iranian aggression, and reaffirms transatlantic resolve in countering terrorism and proliferation.
FDD Action Expert Analysis
“For years, Iran has exploited diplomacy as a stalling tactic to advance its nuclear program and strengthen its terror proxies. The E3 must not allow Tehran to run out the clock. Holding firm on snapback is the only way to reimpose meaningful pressure, restore international credibility, and deny the regime the breathing room it craves. Weakness invites more nuclear extortion; resolve shuts it down.”
