Nuclear Issues

Secretary of State Mike Pompeo’s most recent announcement on Iran policy has raised some eyebrows. He indicated on Monday morning that the Trump administration will not renew waivers to importers of Iranian crude and that other suppliers (meaning Saudi Arabia) have agreed to increase production in to ensure the global oil market remains well-supplied. Skeptics question whether — after last summer’s debacle — there is sufficient trust between Washington and Riyadh for this arrangement to work. What skeptics may not have digested is that, while timing remains a problem, this is a classic win-win situation. It is a near-perfect example of the very limited universe of occasions when transactional diplomacy could actually work.

Nuclear security around the world has improved dramatically over the last three decades—which demonstrates that with focused leadership, major progress is possible. But important weaknesses remain, and the evolution of the threat remains unpredictable. The danger that terrorists could get and use a nuclear bomb, or sabotage a major nuclear facility, or spread dangerous radioactive material in a “dirty bomb,” remains too high. The United States and countries around the world need to join together and provide the leadership and resources needed to put global nuclear security on a sustained path of continuous improvement, in the never-ending search for excellence in performance.

Last May, Chinese solar panel manufacturer LONGi signed an agreement with Saudi trading company El Seif Group to establish large-scale solar manufacturing infrastructure in Saudi Arabia. The deal came several months after the Trump administration's imposition of global tariffs on imports of Chinese solar panels and cells.

This article reconstructs the history of China’s production of highly enriched uranium and plutonium for nuclear weapons based on newly available public sources. It begins with discussion of China’s first set of fissile-material production facilities, which China started building in 1958. It then details the first and second “third-line” construction campaigns, initiated in 1964 and the late 1960s, respectively. Finally, the article considers the policy implications of the history of China’s fissile-material production, particularly its influence on China’s attitude toward negotiating a fissile-material cutoff treaty.

All the world's nuclear-armed states (except for North Korea) have begun modernizing and upgrading their arsenals, leading many observers to predict that the world is entering a new nuclear arms race. While that outcome is not yet inevitable, it is likely, and if it happens, the new nuclear arms race will be different and more dangerous than the one we remember. More nuclear-armed countries in total, and three competing great powers rather than two, will make the competition more complex. Meanwhile, new non-nuclear weapon technologies — such as ballistic missile defense, anti-satellite weapons, and precision-strike missile technology — will make nuclear deterrence relationships that were once somewhat stable less so.

The operation of the fleet of Chinese floating nuclear power plants in the South China Sea carries with it numerous safety and security risks that may have widespread consequences to not only China but also to Southeast Asia and beyond.

China’s military could play a vital role in securing or destroying Pyongyang’s nuclear weapons if the North Korean regime collapsed.

The risks of nuclear escalation between the U.S. and China or Russia are greater than ever given the possibility of misinterpreted cyber espionage and military strikes against early warning systems. What can be done to reduce this risk?

Drawing from the legacy of his friend and mentor Thomas Schelling, former Belfer Center director Graham Allison outlines the most pressing nuclear challenges that America faces today.
