The 2016 nuclear security summit was a pivotal moment for the decades-long effort to secure nuclear material around the globe. More than 50 national leaders gathered in Washington for the last of four biennial meetings that have led to significant progress in strengthening measures to reduce the risk of nuclear theft.

When do states acquire nuclear weapons? History shows that only two types of states decide that the bomb is essential to their security: 1) very powerful states; and 2) weak states that lack ironclad security guarantees.

Policymakers have long focused on preventing nuclear weapons proliferation by controlling technology. Even developing countries, however, may now possess the technical ability to create nuclear weapons. The history of gas centrifuge development in twenty countries supports this perspective. To reduce the demand for nuclear weapons, policymakers will have look toward the cultural, normative, and political organization of the world.

"The United States and Pakistan recently initiated a promising series of high level talks to develop a strategic relationship between the two countries. Even in pursuit of such an expanded bilateral agenda, however, lowering the risks associated with Pakistan's nuclear weapons must stand at the top of the list of priorities."

"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."

"...[A] primary goal in the next decades must be to remove this risk of near global self-destruction by drastically reducing nuclear forces to a level where this outcome is not possible, but where a deterrent value is preserved — in other words, to a level of minimum deterrence. This conception was widely discussed in the early years of the nuclear era, but it drowned in the Cold War flood of weaponry. No matter how remote the risk of civilization collapse may seem now — despite its being so vivid only a few decades ago — the elimination of this risk, for this century and centuries to come, must be a primary driver for radical reductions in nuclear weapons."

"The greatest threat of a loose nuke scenario stems from insiders in the nuclear establishment working with outsiders, people seeking a bomb or material to make a bomb. Nowhere in the world is this threat greater than in Pakistan."

"All of these pathologies were evident in the failure to prevent or appropriately respond to the Mumbai attacks. There was in fact significant intelligence suggesting a seaborne terrorist attack was likely, and even that prominent sites such as the Taj Hotel would be targeted. This information, however, was ignored by several key bureaucratic actors—including the Coast Guard and the Maharashtra state director-general of police—because it was deemed unactionable. Others, such as the Maharashtra Anti-Terrorism Squad, at least attempted some kind of preparation. The differences in readiness highlight the extent of fragmentation among the security apparatus. Even when Mumbai police tried to take preventive action, they lacked the manpower to sustain increased security at the hotels. Once the attack occurred, the security forces did not have sufficient night-vision equipment, heavy weaponry, or information about the attack sites, leading to a long response time and the emergence of a disastrous siege...."

"If the Pakistani authorities cannot or will not play their part, a way should be found to scale back significantly the U.S. and NATO military commitment in Afghanistan. Our fundamental problem, it should be emphasized, is with Al Qaeda, and secondarily with the Taliban, who sheltered Al Qaeda. We cannot be perceived as moving toward a colonial war, as happened in Vietnam...."
