Nuclear Issues

Nuclear security around the world has improved dramatically over the last three decades—which demonstrates that with focused leadership, major progress is possible. But important weaknesses remain, and the evolution of the threat remains unpredictable. The danger that terrorists could get and use a nuclear bomb, or sabotage a major nuclear facility, or spread dangerous radioactive material in a “dirty bomb,” remains too high. The United States and countries around the world need to join together and provide the leadership and resources needed to put global nuclear security on a sustained path of continuous improvement, in the never-ending search for excellence in performance.

On Friday, North Korea tested a missile than can deliver a nuclear weapon to almost any target in the continental United States, marking a major accomplishment for a state than many thought was on its last legs in the early 1990s. But far from dead, North Korea has managed to evade every political, military, and economic barrier that five successive U.S. presidents put in its way. Now, the United States under President Donald Trump has a massive but surmountable challenge on its hands—deterring a nuclear-armed North Korea and preserving and strengthening America’s alliances with South Korea and Japan, countries currently questioning whether Kim Jong Un’s new capabilities might prevent the United States from coming to their defense.

"From Hiroshima to the Cuban Missile Crisis, from arms races to arms control, from the Cold War and its proxy wars to the 2003 invasion of Iraq and the 2015 deal with Iran, few subjects have so consistently, and so controversially, concerned the American presidency as nuclear weapons have. A dozen men have been responsible for the decision to use the US nuclear arsenal since 1945, and whoever wins the election in November will inherit the responsibility for approximately 4,670 warheads at a time when relations with Russia (holder of 4,500 warheads) have reached a perilous low, a time when support for arms control is perhaps faltering, and a time when nuclear threats abound from the Middle East to the Korean Peninsula..."

Leading up to and during the 2016 Nuclear Security Summit, Belfer Center experts released reports, published commentary, and provided insight and analysis into global nuclear security. In advance of the Summit, the Project on Managing the Atom set the stage for discussion with the report Preventing Nuclear Terrorism: Continuous Improvement or Dangerous Decline?

An in-progress compilation of the expert commentary and analysis is available here.

Fifty-plus countries are attending the 2016 Nuclear Security Summit this week in Washington, DC. Notably missing from the guest list is Iran, whose recent negotiation and implementation of a landmark nuclear deal with the P5+1 led some experts to call for more engagement and cooperation in nuclear security.

"Today and tomorrow, world leaders will gather for what will likely be the final international summit on security for nuclear weapons and the materials needed to make them—a key tool for preventing nuclear terrorism. The last time this group met, at the 2014 Nuclear Security Summit in the Hague, they declared that preventing terrorists from acquiring nuclear weapons or weapons-usable materials remained “one of the most important challenges in the years to come.” Yet, since then, nuclear security has improved only marginally, while the capabilities of some terrorist groups, particularly the Islamic State, have grown dramatically, suggesting that in the net, the risk of nuclear terrorism may be higher than it was two years ago..."

At a meeting 23 and 24 March in Belgrade, US and Russian members of the Elbe Group – retired general officers from the military and intelligence services – declared that the risk of terrorism, both conventional and nuclear, is growing.  They urged that special attention must be given to preventing Daesh, al Qaeda, and other terrorist organizations which have declared openly their desire to gain weapons of mass destruction, from obtaining them.

"As world leaders gather for the fourth nuclear security summit this week, in the aftermath of the horrifying terrorist attacks in Brussels, it seems likely that Belgian Prime Minister Charles Michel will have more to say than anyone else — both about real nuclear terrorist dangers and about real steps taken to improve nuclear security...."
