What's happened
The U.N. Security Council sanctions remain in effect, with France, Germany and the United Kingdom having triggered the snapback mechanism in 2025. A U.N. expert panel was not appointed due to consensus gaps, while the United States and allies pursue further isolation of Iran amid ongoing tensions surrounding Iran’s nuclear program and sanctions enforcement.
What's behind the headline?
What’s happening now
- The Security Council maintains sanctions and a monitoring framework that remains stalled in practice as several major powers veto the extension of the expert panel.
- Iran’s compliance status continues to be contested amid tensions from the Israel/U.S. strike on Iranian sites in 2025 and ongoing inspections.
Why it matters
- The absence of an independent monitoring panel creates a reporting gap that could obscure violations and complicate enforcement.
- The dispute highlights geopolitical fault lines among Security Council members, with Russia and China opposing what they view as Western efforts to politicize the council.
What to watch
- Whether a new, consensus-based mechanism for monitoring sanctions emerges and how it is designed to pair with future sanctions enforcement.
- Possible shifts in alliance coalitions as Tehran navigates renewed pressure from Western powers.
How we got here
Sanctions were reimposed in 2025 after Western powers accused Tehran of violating the 2015 nuclear pact. A bid to extend the U.N. expert panel’s mandate failed due to Russian and Chinese vetoes, leaving the council without an independently appointed monitoring body amid ongoing questions about Iran’s nuclear program and compliance.
