Nuclear Issues

The most significant achievement to emerge from the 2014 Nuclear Security Summit was a pledge by 35 countries to observe the terms of a joint agreement, known as Strengthening Nuclear Security Implementation. Promoted strongly by the chairs of all three nuclear summits—the United States, South Korea, and the Netherlands— the 2014 initiative is an important step towards creating a robust global security system designed to prevent nuclear materials from falling into the hands of terrorists. Yet China, along with Russia, India, and Pakistan, did not join the pledge. Beijing has not offered any explanations. China not only can join the new initiative, it should join it—because joining is in China’s own national interest.

While the United States and Russia have a responsibility to draw down their arsenals, these bilateral nuclear reductions will be increasingly difficult if other nuclear powers do not join in....[I]t is time to engage the so-called "second tier" nuclear powers, especially China. The evolution of the US-China strategic relationship can affect the next stages of international arms control, even if China does not directly participate.

The Winter 2010/11 issue of the Belfer Center newsletter features recent and upcoming activities, research, and analysis by members of the Center community on critical global issues. This issue highlights a major Belfer Center conference on technology and governance, the Center's involvement in the nuclear threat documentary Countdown to Zero, and a celebration of Belfer Center founder Paul Doty.

"...[T]he United States has spent several tens of billions of dollars on missile defense research-and yet China, Iran, North Korea and possibly others have continued to pursue increasingly effective long-range ballistic capabilities. If missile defenses are a deterrent, why do US competitors-to say nothing of outright enemies-seem undeterred?"

"Chinese officials have expressed a growing concern that U.S. space and missile defense plans will stimulate a costly and destabilizing arms race...."

Despite extensive diplomatic efforts to facilitate the six-party talks, domestic policy constraints, differing priorities, and conflicting historical analogies among each of the countries have brought vastly differing perspectives to the multilateral negotiating table.

A universal Fissile Material Cut-off Treaty (FMCT), which would ban the production of fissile material (separated plutonium, highly enriched uranium (HEU), and uranium-233) for nuclear weapons, has long been seen as a key building block in nuclear disarmament and non-proliferation.

Nuclear terrorism is a realistic threat to all countries. First, this article describes the potential threats of nuclear terrorism including nuclear explosives, nuclear sabotage, and dirty bombs. Finally, this article recommends steps to secure nuclear weapons, nuclear materials, and nuclear facilities.
