In a televised speech on January 1, Iranian President Hassan Rouhani said that Tehran had imported 200 metric tons of yellowcake uranium and would import another 120 tons at an unspecified future date. The imports are permitted by the nuclear deal, the Joint Comprehensive Plan of Action (JCPOA), but nonetheless significantly exceed Iran’s needs for natural (that is, unenriched) uranium over the next 15 years. Iran’s import of such high levels of uranium suggests it may be stockpiling uranium to reach nuclear breakout before the deal’s initial limitations expire in 2031.

The JCPOA permits Iran to buy natural uranium to “replenish” its stocks as it sells enriched uranium on the international market. To date, Iran has had difficulties locating a buyer for its enriched uranium stocks – unsurprising, given the current excess of commercially available enriched uranium. This, however, has not stopped Iran from buying and stockpiling more yellowcake.

"Creating innovation universities can be pursued through three practical stages. The first is to formulate a policy framework under which such universities operate. The second state is to translate the policy into specific legislative reforms to support the new university species. The third stage is to experiment by upgrading a few research institutes that have strong foundations and potential to commercialize products and services."

Most histories of post-1945 U.S. grand strategy focus on containment of the Soviet Union and U.S. efforts to promote political and economic liberalization. A closer look reveals that "strategies of inhibition"—attempts to control nuclear proliferation—have been a third central pillar of U.S. grand strategy for several decades.

How does the acquisition of nuclear weapons affect states' foreign policy? A new typology of six potential post-acquisition state behaviors—aggression, expansion, independence, bolstering, steadfastness, and compromise—offers a more nuanced answer to this question than previous studies have provided. The United Kingdom's foreign policy after it developed the bomb reveals how nuclear weapons can make a country more assertive.
