With U.S.-North Korea tensions heightened after weeks of fiery and furious rhetoric from President Trump and Kim Jong-un—pushing the world closer to nuclear conflict than it has been in decades—it’s worth taking a breath to consider what forces have kept the world’s nuclear-armed states from irradiating and annihilating each other in a shower of bombs.

Scott D. Sagan and Benjamin A. Valentino conducted a clever survey experiment to test Americans’ attitudes on the use of nuclear weapons. They summarize their findings in the current issue of International Security.

Americans are disturbingly unbothered by the idea of striking first with nuclear weapons.

According to a study published last week in International Security, a preeminent academic journal of international affairs, the strength of the nuclear taboo in America has been wildly overestimated. 

Since the 1945 nuclear attacks on Hiroshima and Nagasaki, have Americans developed moral taboos against using nuclear weapons and killing noncombatants?

Now that they are in office, President Donald Trump and his team must protect the nation from many threats – including from insiders. Insider threats could take many forms, such as the next Edward Snowden, who leaked hundreds of thousands of secret documents to the press, or the next Nidal Hasan, the Fort Hood mass killer.

High-security organizations around the world face devastating threats from insiders—trusted employees with access to sensitive information, facilities, and materials. From Edward Snowden to the Fort Hood shooter to the theft of nuclear materials, the threat from insiders is on the front page and at the top of the policy agenda. Insider Threats offers detailed case studies of insider disasters across a range of different types of institutions, from biological research laboratories, to nuclear power plants, to the U.S. Army. Matthew Bunn and Scott D. Sagan outline cognitive and organizational biases that lead organizations to downplay the insider threat, and they synthesize "worst practices" from these past mistakes, offering lessons that will be valuable for any organization with high security and a lot to lose

Insider threats are perhaps the most serious challenges that nuclear security systems face. Insiders perpetrate a large fraction of thefts from heavily guarded non-nuclear facilities as well, yet organizations often find it difficult to understand and protect against insider threats. Why is this the case? Part of the answer is that there are deep organizational and cognitive biases that lead managers to downplay the threats insiders pose to their nuclear facilities and operations. But another part of the answer is that those managing nuclear security often have limited information about incidents that have happened in other countries or in other industries, and the lessons that might be learned from them.

"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."
