Nuclear Issues

Contrary to conventional wisdom, states with nuclear energy programs are not more likely than those without them to seek or acquire nuclear weapons.

This article reviews the motivations, strengths, and weaknesses of the Nuclear SecuritySummits (NSS), both procedurally and substantively.

Indian Prime Minister Narendra Modi traveled to Washington last week, making his fourth trip to the United States since taking office just two years ago. India and South Asia Program Fellow, Ronak Desai examines the strategic approach to India's relations with the United States.

Pakistan has developed tactical nuclear weapons to deter India from executing its Cold Start war doctrine. India, however, has disavowed that doctrine. Further, the use of such weapons against Indian troops inside Pakistan would kill and injure countless civilians, while risking massive nuclear retaliation by India. In this International Security article, Jaganath Sankaran argues Pakistan should reconsider the role of tactical nuclear weapons in its military strategy.

Campbell Craig and Benjamin H. Friedman, Brendan Rittenhouse Green, and Justin Logan respond to Stephen G. Brooks, G. John Ikenberry, and William C. Wohlforth's Winter 2012/2013 International Security article, "Don't Come Home, America: The Case against Retrenchment."

Many experts consider nuclear terrorism the single greatest threat to U.S. security. The fear that a state might transfer nuclear materials to terrorists was a core justification for the invasion of Iraq in 2003 and, more recently, for a strike against Iran’s nuclear program. The logical basis for this concern is sound: if a state could orchestrate an anonymous nuclear terror attack, it could destroy an enemy yet avoid retaliation. But how likely is it that the perpetrators of nuclear terrorism could remain anonymous? Data culled from a decade of terrorist incidents reveal that attribution is very likely after high-casualty terror attacks. Attribution rates are even higher for attacks on the U.S. homeland or the territory of a major U.S. ally—97 percent for incidents in which ten or more people were killed. Moreover, tracing a terrorist group that used a nuclear weapon to its state sponsor would not be difficult, because few countries sponsor terror; few terror groups have multiple sponsors; and only one country that sponsors terrorism, Pakistan, has nuclear weapons or enough material to manufacture them. If leaders understand these facts, they will be as reluctant to give weapons to terrorists as they are to use them directly; both actions would invite devastating retaliation.

"While journalists have provided a number of histories of the events that led to bin Laden's death, the purpose of this analysis is to examine White House decisionmaking for lessons that can be applied to future foreign policy challenges."

In a TIME magazine cover story, Belfer Center Director Graham Allison writes about decisions behind the raid that led to the death of Osama bin Laden. Allison, whose analysis is the result of more than 100 hours of interviews, is author of the prize-winning analysis of the 1971 Cuban Missile Crisis, Essence of Decision.

After decades of flirting with nuclear weapons, India finally emerged as a nuclear power in the 1990s. New evidence suggests that India was able to hold off in part because it was able to secure protection through an alternate method: implicit “umbrellas” from superpowers. In the late 1970s, however, U.S. support for India waned as it began to improve its relations with Pakistan, and India lost its other major backer with the dissolution of the Soviet Union. By the late 1980s, India could no longer protect itself through diplomatic means, and acquisition of the bomb became an inevitable response to its security needs.

"Our crystal ball is not clear enough to predict with confidence whether the global nuclear future will be characterized by peace and prosperity or by conflict and destruction. But we do believe that the choices made in the coming few years will be crucial in determining whether the world can have more nuclear power without more nuclear weapons dangers in the future."

"Keeping nuclear weapons and the difficult-to-manufacture materials needed to make them out of terrorist hands is critical to U.S. and world security — and to the future of nuclear energy as well. In the aftermath of a terrorist nuclear attack, there would be no chance of convincing governments, utilities, and publics to build nuclear reactors on the scale required for nuclear energy to make any significant contribution to coping with climate change."
