Secretary of Energy Ernest Moniz wrote on op ed in the Washington Post a few days ago on the proposed nuclear deal between the international community and Iran. While many don’t seem to know it, the DoE’s primary responsibility is oversight of various nuclear facilities, so it would be the agency most qualified to respond to the technical (rather than political) details of the deal. Moniz is also an emeritus professor physics at MIT. Moniz emphasizes that the deal, if it passes in the end, would achieve many of the goals that the US and other countries want, which is to prevent the development of nuclear weapons or at least make it hard enough to delay anything. It would also allow Iran to continue a civilian nuclear program, which is what it claims it wants anyway while making it difficult to evade limitations on fuel enrichment.
