Iran has significantly increased its stockpile of uranium enriched to near weapons-grade levels, according to a confidential report by the International Atomic Energy Agency (IAEA). As of August 17, Iran possesses 363.1 pounds of uranium enriched up to 60%, an increase of 49.8 pounds since May. This level of enrichment is just a technical step away from the 90% needed for weapons-grade material. IAEA chief Rafael Mariano Grossi has warned that Iran now has enough enriched uranium to potentially create several nuclear bombs. Despite a resolution demanding improved cooperation, Iran has not allowed experienced inspectors to monitor its program and continues to bar IAEA surveillance. The report comes amidst strained relations and stalled nuclear diplomacy, although Iran’s supreme leader has recently expressed openness to renewed negotiations with the U.S.
