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.

The authors write that Vietnam will play host to a critical meeting between Donald Trump and Kim Jong Un, and it will benefit from their peace efforts regardless of the outcome.

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.

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.

An estimated 14,485 nuclear weapons exist on earth today — most are far more powerful than those that twisted railway ties, leveled buildings, and crushed, poisoned, and burned human beings in Hiroshima and Nagasaki. The majority of these weapons belong to the United States and Russia. For some in the U.S. government, including Chris Ford, assistant secretary at the State Department’s Bureau of International Security and Nonproliferation, this number represents significant disarmament progress since Cold War highs of over 70,000 nuclear weapons. They argue the current security environment means that further reductions are not possible at this time. In contrast, for many disarmament advocates and officials from non-nuclear weapons states, this number is still far too high. They are now clamoring to ban all nuclear weapons. Because of this divide, according to Ford, we currently face a “disarmament crisis.”

Over the past few weeks, BTS members have found themselves entangled in a bizarre scandal over an “atomic bomb shirt” that led to the cancellation of their appearance on a popular TV Asahi music show in Japan, which has been the main foreign source of revenues for K-pop groups since the 1990s. The 23-year-old singer, Jimin, was caught on the street wearing a white t-shirt bearing the slogan “Patriotism Our History Liberation Korea” repeated in numerous lines and overlapped by a black-and-white picture of the mushroom cloud from the atomic bomb that the United States detonated over Nagasaki, Japan on August 9, 1945.

The nuclear weapons taboo is considered one of the strongest norms in international politics. A prohibition against using nuclear weapons has seemingly shaped state behavior for nearly seven decades and, according to some observers, made nuclear use ‘unthinkable’ today or in the future. Although scholars have shown that nuclear aversion has affected decision-making behavior, important questions about the nuclear taboo remain unanswered. This article seeks to answer a basic question: How durable is the taboo? We develop different predictions about norm durability depending on whether the taboo is based primarily on moral logic or strategic logic. We use the comparable case of the norm against strategic bombing in the 20th century to evaluate these hypotheses. The logic and evidence presented in this paper suggest that the norm of nuclear non-use is much more fragile than most analysts understand.

Steven E. Miller writes that U.S. withdrawal from the Intermediate Range Nuclear Forces Treaty offers few benefits and solves no significant security problem, while raising some potential costs and obvious disadvantages.
