Nuclear Issues

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.

On Friday, North Korea tested a missile than can deliver a nuclear weapon to almost any target in the continental United States, marking a major accomplishment for a state than many thought was on its last legs in the early 1990s. But far from dead, North Korea has managed to evade every political, military, and economic barrier that five successive U.S. presidents put in its way. Now, the United States under President Donald Trump has a massive but surmountable challenge on its hands—deterring a nuclear-armed North Korea and preserving and strengthening America’s alliances with South Korea and Japan, countries currently questioning whether Kim Jong Un’s new capabilities might prevent the United States from coming to their defense.

In this Project on Managing the Atom Discussion Paper, Philipp C. Bleek chronicles nuclear weapons proliferation choices throughout the nuclear age. Since the late 1930s and early 1940s, some thirty-one countries are known to have at least explored the possibility of establishing a nuclear weapons program. Seventeen of those countries launched weapons programs, and ten acquired deliverable nuclear weapons.

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.
