Nuclear Issues

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

Senior Fellow William H. Tobey evaluates the effectiveness of President Obama's policies to stem the threats of nuclear proliferation and terrorism.

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.

During the Cold War, the threat of a nuclear attack came mainly from the U.S.-Russian nuclear arsenals, writes Kevin Ryan. Today, however, the United States and Russia have been forced to adapt to a new nuclear threat—that of dedicated terrorists with money and technological access who seek to obtain and use a nuclear device.

In 1985, researchers at the Harvard Kennedy School published a book called “Hawks, Doves, and Owls,” and gave it an ambitious subtitle: “An Agenda for Avoiding Nuclear War.” Those scholars gathered again at the School on Monday (May 16) for a seminar on the current challenges in avoiding nuclear war — and to marvel at just how drastically the nuclear threat has morphed in the two decades since the Cold War ended and the Soviet Union collapsed.

Recent national trends in investments in global energy research, development, and demonstration (RD&D) are inconsistent around the world. Public RD&D investments in energy are the metric most commonly used in international comparative assessments of energy-technology innovation, and the metric employed in this article. Overall, the data indicate that International Energy Agency (IEA) member country government investments have been volatile: they peaked in the late 1970s, declined during the subsequent two decades, bottomed out in 1997, and then began to gradually grow again during the 2000s.

An update from U.S.-Russia Initiative to Prevent Nuclear Terrorism for November 26-December 3, 2010.

"Nuclear terrorism poses a unique threat not only because of the magnitude of the destruction, but because those most likely to perpetrate an attack may be fundamentally nihilistic and therefore undeterrable — prepared to pay any cost in loss of life in pursuit of their objectives. As millennial movements for whom the crippling and even destruction of the U.S. and Israel are sacred missions, a nuclear terrorist attack where even a devastating response is assumed may be a worthy means of ushering in a messianic era."

Where are the sources of greatest threat today? Where is nuclear catastrophe most likely to occur over the next decade?  If we are able to anticipate the breaking news of a nuclear security meltdown, it stands to reason we might be able to prevent it from becoming tomorrow's news.

"Thinking about risks we face today, we should reflect on the major conclusion of the bipartisan 9/11 Commission established to investigate that catastrophe. The U.S. national security establishment's principal failure prior to Sept. 11, 2001, was, the commission found, a "failure of imagination."Summarized in a single sentence, the question now is: Are we at risk of an equivalent failure to imagine a nuclear 9/11? After the recent attempted terrorist attack on Northwest Airlines Flight 253, this question is more urgent than ever."
