As the U.N. Security Council considers tightening sanctions on Iran, Russia put its displeasure with the Iranians on full display this week. The country signaled that it will refuse to complete a nuclear reactor it is building in Iran unless Tehran agrees to a pause in its uranium enrichment and a return to negotiations.
Publicly, Iranian leaders remain defiant. But behind the scenes, there are signs the pressure may be working. The Security Council could vote on a new sanctions resolution at the end of this week.
