    Threat Assessment Brief
    July 25, 2012

    A long submerged flaw in the nuclear Non-Proliferation Treaty (NPT) surfaced conspicuously in June when Iran announced it intended to build a nuclear-powered submarine.

    Threat Assessment Brief
    June 28, 2012

    On June 19, Iran concluded the third round of talks on its nuclear program in as many months, this time in Moscow, with senior officials of the six powers - the United States, the United Kingdom, France, Germany, Russia, and China. Although there were strong incentives for the six to secure limits on Iran's most worrisome stockpiles of enriched uranium and for Iran to avoid an impending tightening of economic sanction, no breakthrough was achieved by the end of the latest round. But neither did diplomatic dialogue come to an end.
