A Global Analysis of CO2 and Non-CO2 GHG Emissions Embodied in Trade with Belt and Road Initiative Countries

| 2020

The Belt and Road Initiative (BRI) is an important cooperative framework that increasingly affects the global economy, trade, and emission patterns. However, most existing studies pay insufficient attention to consumption-based emissions, embodied emissions, and non-CO2 greenhouse gases (GHGs). This study constructs a GHG emissions database to study the trends and variations in production-based, consumption-based, and embodied emissions associated with BRI countries

Deescalation Wanted: How Trump Can Steer Clear of a War

| June 26, 2019

The United States and Iran have engaged in a constant raising of the stakes as a means of securing leverage ahead of possible nuclear negotiations. This is a classic bargaining pattern but in the current context, such an approach is particularly risky due to the potential for misperceptions. The complexities of domestic and regional dynamics are also a factor. In such a situation, absent clear understanding of the other’s motivations and tactics, raising the stakes—rather than securing leverage for effective negotiations—could steer the United States and Iran towards a path toward war.

Trump's Trade Policy May Deflate His "Maximum Pressure" Campaigns

| June 10, 2019

Although Trump did not outline his legal basis for imposing the tariffs, several analysts anticipated that he was seeking to use the authorities granted him under the International Emergency Economic Powers Act—the legal basis that presidents rely on to impose financial and economic sanctions against WMD proliferators, terrorist organizations, narco-traffickers, and human rights abusers. Mixing trade and immigration policy under the guise of a national security threat, however, may end up deflating Trump’s “maximum pressure” sanctions campaigns against Iran and North Korea.

China's Calculus After the INF Treaty

| May 08, 2019

It seems that the Intermediate-Range Nuclear Forces (INF) Treaty is coming to an end. The Treaty prohibits the United States and Russia from possessing, producing or testing land-based ballistic and cruise missiles with ranges of 500–5500 kilometres, including both conventional and nuclear-armed missiles. On 1 February 2019, US President Trump said that he would suspend obligations under the INF Treaty and initiate the withdrawal procedure. After withdrawing, the United States might deploy conventional and nuclear missiles to the West Pacific against China. How would the potential deployment of each missile type impact China’s security?

Senator Richard G. Lugar: An Appreciation

| Apr. 30, 2019

Sen. Richard Lugar—with his legislative partner, Sen. Sam Nunn—imagined the unimaginable. He championed a program to provide assistance to military forces in the former Soviet republics holding tens of thousands of nuclear, chemical, and biological weapons aimed at the United States and our allies, shortly after America’s existential enemy, the Soviet Union, expired. All told, the Nunn-Lugar cooperative threat reduction program provided more than $14 billion to, among other things, deactivate 13,300 nuclear warheads, eliminate 1,473 intercontinental ballistic missiles, and destroy almost 40,000 metric tons of chemical agents. The US departments of Defense and Energy also worked with Russia to improve security at 148 sites still holding nuclear weapons or weapons-grade material from Murmansk to Kamchatka.

The Iran Nuclear Archive: Impressions and Implications

In mid-January, a team of scholars from the Belfer Center’s Intelligence and Managing the Atom Projects traveled to Tel Aviv, Israel to examine samples of, and receive briefings on, an archive of documents related to Iran’s nuclear weapons program. The large cache includes some 55,000 pages of documents and a further 55,000 files on CDs that included photos and videos. A clandestine Israeli intelligence operation spirited the materials out of Iran in early 2018.

The documents that the Belfer group were shown confirm that senior Iranian officials had decided in the late 1990s to actually manufacture nuclear weapons and carry out an underground nuclear test; that Iran’s program to do so made more technical progress than had previously been understood; and that Iran had help from quite a number of foreign scientists, and access to several foreign nuclear weapon designs. The archive also leaves open a wide range of questions, including what plan, if any, Iran has had with respect to nuclear weapons in the nearly 16 years since Iran’s government ordered a halt to most of the program in late 2003. 

This brief report summarizes the group’s conclusions about what the archive reveals about Iran’s program and questions that remain open.

The Future of the Nuclear Order

| April 2019

Foreign policy pundits have bemoaned the unraveling of the post-World War II international order in recent years, describing threats to the multilateralism and liberalism enshrined in postwar institutions. An often overlooked component of that structure is the global nuclear order, which, like other parts of the postwar system, was created for magnanimous and selfish aims: reducing the dangers of nuclear weapons for all and serving the interests of the world’s most powerful states.

Dim Hope for Disarmament and Approaching Risk of Build-Up

| March 2019

Further nuclear reduction under the current regimes seems unlikely. The US argues that Russia has violated the INF Treaty by developing and deploying a land-based cruise missile. Russia also makes the accusation that the Aegis Ashore missile defense system in Europe, capable of launching cruise missiles, has violated the INF. Furthermore, President Trump has repeatedly expressed his unwillingness to extend the New START Treaty for five more years after it expires in February 2021. The US-Russia bilateral disarmament process seems to have terminated. There have been some signs of nuclear build-up. The new US Nuclear Posture Review emphasizes the role of nuclear weapons while de-emphasizing strategic stability, reduces the threshold for nuclear use and calls for developing new low-yield SLBM and sea-launched cruise missiles. America’s nuclear policy might stimulate Russia and China to build new nuclear capabilities. North Korea’s advances in nuclear and long-range missile programs justify Washington’s investment in homeland missile defense, which in turn undermines China and Russia’s nuclear retaliatory capability and might result in a defense-offense arms race.

Can a small nuclear weapon really make the world safer? In this installment of “Say WHAT?”—the Bulletin video series that casts a clear eye on fuzzy policy—we ask nuclear weapons expert Sébastien Philippe what he thinks about the latest nuclear craze.

Revitalizing Nuclear Security in an Era of Uncertainty

| January 2019

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.
