Science, Technology, and Public Policy

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.

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.

For true political and strategic stability in Southern Asia, China must be involved as a committed party to India-Pakistan confidence building measures, argues Frank O'Donnell in South Asian Voices' series, "Twenty Years Into Nuclear South Asia."

India's nuclear profile, doctrine, and practices have evolved rapidly since the country's nuclear breakout in 1998. However, the outside world's understanding of India's doctrinal debates, forward-looking strategy, and technical developments are still two decades behind the present. India and Nuclear Asia will fill that gap in our knowledge by focusing on the post-1998 evolution of Indian nuclear thought, its arsenal, the triangular rivalry with Pakistan and China, and New Delhi's nonproliferation policy approaches. The authors show how India's nuclear trajectory has evolved in response to domestic, regional, and global drivers.

Nuclear weapons remain the most powerful weapons on the planet and how President Donald Trump’s team manages nuclear issues is critical to our security. These are hard challenges; none were perfectly addressed under President Obama’s leadership. But we made them a priority from day one. Whether or not the new team puts them at the top of the to-do list, here are five issues that will demand their attention before too long.
