Russia and China Block U.N. Monitoring Extension for Iran Nuclear Program

At the United Nations on Thursday, the Security Council's capacity to watch over Iran's nuclear program quietly fractured, as Russia and China vetoed a U.S.-backed resolution to extend international inspection mandates. The act was less a single diplomatic event than a symptom of a deeper realignment — one in which the great powers no longer share even a common language for managing nuclear risk. What was once treated as routine oversight has become a theater of geopolitical contest, leaving the world with less visibility into one of its most consequential uncertainties.
