The Islamic Republic of Iran has taken retaliatory actions against the Biden administration's support of a U.N. watchdog agency rebuke regarding Tehran's covert illicit nuclear weapons program. The International Atomic Energy Agency (IAEA) confirmed that Iran has started feeding uranium into advanced IR-4 and IR-6 centrifuges at its Natanz enrichment facility. These cascades of centrifuges are being used to enrich uranium up to 2% purity, with the capability to reach 60%, a step away from weapons-grade levels.
Israel's former Defense Minister has raised concerns about Iran's intentions, stating that Iran is planning a potential threat in the coming years. The U.S. State Department has criticized Iran's nuclear program, emphasizing that Iran's actions do not have a credible peaceful purpose. The State Department has labeled Iran as the world's worst state-sponsor of terrorism.
