Today, the origins of the concept of RW have largely been forgotten.  Indeed, since 9/11, radiological weapons have been associated mainly with non-state actors, who may not have the means or motivations to acquire and use far more lethal nuclear explosives.  A fixation on the very real dangers posed by nuclear terrorism, however, should not obscure the risks that states also may again pursue radiological weapons.

Jayita Sarkar explains why the Biden administration needs to re-conceptualize nuclear terrorism and act quickly.

On August 6, 1945, the United States dropped an atomic bomb on Hiroshima, Japan, launching the nuclear age. On the 75th anniversary of that somber event, Belfer Center experts reflect on the event and its aftermath. 

Rebecca Davis Gibbons and Stephen Herzog provide an update on current efforts to eliminate nuclear weapons. 

Despite the continuing debate in Tehran, the principle of “no negotiation under pressure” with the United States remains a consensual principle among all members of the current regime. The Supreme Leader has expressed this position by stating that the negotiations with the Trump administration are “double poison”. While Iran’s regional enemies are pushing for confrontation, the international community remains supportive of Tehran’s political position, as long as it stays committed to the nuclear deal. Existing indicators do not point at any willingness for confrontation from either side – at least at the moment. And although some regional actors have attempted to pacify the tension, the prospects for a truce remain unlikely within the current context.

Harvard Kennedy School's Belfer Center enthusiastically welcomes back Ambassador Laura Holgate, who began her career at the Center in 1990.
