The United Nations’ International Atomic Energy Agency (IAEA) recently issued an unusually jarring warning, highlighting a development in Iran’s nuclear program. IAEA inspectors confirmed that, for the first time, Iran has commenced the process of feeding uranium gas into three cascades of advanced IR-4 and IR-6 centrifuges at its Natanz enrichment facility. These cascades, which consist of multiple centrifuges working in unison, increase the efficiency of uranium enrichment by spinning the uranium gas at extremely high speeds, allowing Iran to enrich it at a much faster rate and significantly reducing the time required to produce nuclear weapons.
