Analysts warn that entrenched political obstacles may stand in the way of any new multilateral effort to curb nonmilitary uses of bomb-grade uranium.
World leaders have achieved a degree of success since 2010 in reducing the use of highly enriched uranium for civilian needs, such as fueling nuclear reactors and manufacturing medical isotopes, says a May analysis by Miles Pomper and Philippe Mauger of the James Martin Center for Nonproliferation Studies.
They argued, though, that dangers from the material persist. The authors said roughly 54 tons of highly enriched uranium is being used for peaceful purposes across 29 nations, and a U.N. estimate suggests a would-be nuclear terrorist may need to steal as little as 55 pounds to construct a bomb.
Still, that March statement was nonbinding, and Pomper and Mauger argued that more substantial efforts have been hampered by the differing goals of individual governments. The fourth, and possibly final, Nuclear Security Summit is scheduled for 2016 in the United States.
“With the end of the high-level summit process likely approaching in 2016, time is running out to set a clear objective that can muster sustained engagement from the full international community,” the authors wrote. They pressed for participants in the upcoming gathering to make greater commitments, such as subjecting all nonmilitary highly enriched uranium to international inspections and ultimately ending all civilian use of the material.
“Further HEU stock minimization remains blocked by a few recalcitrant countries, and establishing broader legal principles on HEU management is proving to be difficult,” they wrote in the Stanley Foundation assessment.
Belarus and South Africa have retained stocks of the material for political reasons, while Russia and Germany have resisted transparency initiatives over fears that new measures could “shed poor light” on their uranium holdings, the article says.

Newt Gringrich is actively positioning himself as a possible VP nominee for Donald Trump, according to National Review. After a New York Times piece mentioned him as a possible running mate, he said, "It is an honor to be mentioned. We need a new Contract with America to outline a 100-day plan to take back Washington from the lobbyists, bureaucrats, unions, and leftists. After helping in 1980 with Reagan and 1995 as speaker I know we have to move boldly and decisively before the election results wear off and the establishment starts fighting us. That is my focus." Meanwhile, Trump told CNN he'd be "interested in vetting" John Kasich as well.
"House Democrats are stepping up pressure on Republicans to advance legislation addressing Puerto Rico’s worsening debt crisis by issuing a report arguing that austerity cuts can’t be sustained and have made the island more vulnerable to the mosquito-borne Zika virus." Democrats on the House Natural Resources Committee released a report yesterday that argued "further sharp reductions in government spending can’t be a part of a legislative solution"—especially with a rainy season boosting the mosquito population and stressing an island health system already struggling to deal with the Zika virus.
"ISIS has the capability to stage a Paris-style attack in the U.S. using local cells to strike in multiple locations and inflict dozens of casualties, according to the Obama administration's top U.S. intelligence official." Director of National Intelligence James Clapper told CNN's Peter Bergen that such a scenario is "something we worry about a lot in the United States, that they could conjure up a raid like they did in Paris or Brussels."
