Nuclear Issues

In 2004, the United Nations Security Council adopted resolution 1540, which acknowledged the non-state acquisition of weapons of mass destruction as a security threat and called on member states to implement “appropriate effective” domestic trade controls. The United States, however, has both promoted the multilateral implementation of strategic trade controls but has also increasingly resorted to extraterritorial enforcement of its counterproliferation rules. How can a multilateral, norms-based international regime like 1540 contend with extraterritorial enforcement based on national interests? We argue that increased U.S. extraterritorial counterproliferation policies are a consequence of the inconsistent implementation of resolution 1540, adaptive and resilient proliferation networks, and a history of expanding legal interpretations of jurisdiction. We find that while U.S. extraterritorial enforcement can effectively disrupt networks hiding in overseas jurisdictions, doing so creates disincentives for states to implement 1540 obligations and undermines broader nonproliferation objectives.

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.

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.

‘Third countries’ are frequently exploited by those involved in networks to transfer proliferation-sensitive technologies, allowing procurement agents to obscure the end user or vendor located in the proliferating state, and to deceive industry, export licensing officials, and intelligence services. While ‘third countries’ frequently feature in illicit transactions, the academic literature exploring the roles played by entities in these jurisdictions is limited. Building on the sanctions busting literature, this article proposes a loose typology considering the ways in which third countries can be exploited by proliferation networks. The typology is illustrated using three cases involving entities based in Malaysia – A. Q. Khan’s nuclear black market network, and Iran and North Korea’s efforts to procure and market WMD-related and military goods. These cases are used to generate insights into proliferators’ selection of ‘third country’ hubs. The article argues that while exploitation of third countries by proliferation networks is a similar, but distinct phenomenon to trade-based sanctions busting, hubs of both activities share characteristics. Furthermore, the article argues that other factors beyond the lax regulatory environment, such as level of development, and personal connections, are often as important in driving the decisions of proliferation networks. The article concludes with implications for nonproliferation policy.

This Policy Brief compares and contrasts the Trump administration’s 2018 Nuclear Posture Review with past reviews and its Obama predecessor. It concludes that this review offers a much harsher assessment of the security environment; it posits a more expansive role for nuclear weapons; and proposes a substantial de-emphasis on arms control.
