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.

Despite one of the most extensive sanctions regimes in history, including an embargo on missile technologies, North Korea has taken huge steps forward in its ballistic missile programme. Daniel Salisbury explores the limitations of, and challenges of implementing, supply-side approaches to missile nonproliferation. Considering North Korea’s recent progress and efforts to evade sanctions, the article highlights the continuing need to strengthen efforts to counter illicit trade in missile-related technologies.

Over the past two decades, the United States has increasingly turned to targeted sanctions and export restrictions, such as those imposed against Iran and North Korea, in order to curb the spread of weapons of mass destruction. One vexing problem, however, is how to contend with jurisdictional hurdles when the violations occur overseas, in countries that are unable or unwilling to assist US enforcement efforts. To solve this problem, US prosecutors are turning to strategies with significant extraterritorial implications—that is, exercising legal authority beyond national borders. One such tool is to use civil legal procedures to seize assets linked to sanctions or export-control violations in jurisdictions that lack cooperative arrangements with US enforcement agencies. While this may be an attractive strategy to bolster enforcement efforts against overseas illicit procurement, using such tools is not without consequence. This article explores the political, legal, and technical implications of enforcing extraterritorial controls against overseas non-state actors by exploring the recent uses of civil-asset forfeiture against Iranian and North Korean procurement networks.

If we had the technology to detect nuclear materials remotely it could help deter smuggling and make it easier to monitor international nuclear agreements. Several recent breakthroughs, if followed up with continued research and funding, could deliver on this promise. They include technological advances in x-ray and neutron radiography; a method that measures how plasma breaks down when exposed to a radioactive source; and developments in antineutrino detection. While all require more development and testing, they are important steps as the global need for ways to detect nuclear materials grows.

Since the 1979 revolution, Iran has sought to illicitly procure parts for the U.S. origin fighter aircraft sold to the country under the rule of the Shah. The U.S. has taken steps to quash this trade—these efforts have constituted a relatively large proportion of U.S. export control enforcement over the past near-to-four decades. 

During the latter part of the Cold War, many strategists thought of nuclear deterrence and arms control as two of the most essential stabilizing elements of the same strategy in managing an adversarial relationship. The renewed crisis between the West (the United States and NATO member states) and Russia demonstrates how critical these elements are to the strategic nuclear relationship. As a result of recent setbacks between Washington and Moscow in the past few years, arms control has taken a back seat, and the risk of conflict due to miscalculation is the highest it has been since the 1980s.

Nickolas Roth reflects upon Doomed to Cooperate by Siegfried S. Hecker, which tells the story of how, after the Cold War ended, U.S. and Russian scientists worked together to strengthen Russian nuclear safety and security, reduce proliferation risks, and advance nuclear science. He identifies that the book provides important lessons for policymakers in each country who are, just as they were more than two decades ago, scrambling to cope with the rapidly changing relationship between the world’s two largest nuclear superpowers.
