Asia & the Pacific

David Kearn argues that the idea that the first use of nuclear weapons since 1945 would be by the United States in the defense of Taiwan against a conventional Chinese invasion would have significant, negative, and long-lasting, diplomatic ramifications. It is difficult to fathom the myriad potential consequences, but U.S. nuclear weapon use would almost certainly shatter the non-proliferation regime as a functioning entity, incentivize states (including China) to acquire or improve their existing nuclear arsenal, and damage America's standing globally.

David Kearn argues that even in the absence of restrictive resource and budgetary constraints, a focus on identifying and achieving concrete objectives that will position the United States and its allies to effectively deter aggression in critical regional flashpoints should be the priority given the stressed nature of the defense industrial base and the nuclear enterprise.

Kari A. Bingen and Heather W. Williams write that if Russia plans to deploy nuclear weapons in space to target satellites, the threat is definitely serious—and the U.S. should act fast.

David W. Kearn argues that deployment of nuclear weapons cannot rectify a perceived imbalance in conventional forces in the western Pacific.

Michael Lipin interviews Project on Managing the Atom Associate Nicole Grajewski on why Iran may not benefit much from its new membership of Shanghai Cooperation Organization.

This year's G7 summit in Hiroshima sees nuclear disarmament and non-proliferation sitting high on the agenda, amid rising tensions between the nuclear states and an increasingly divided international order.  Six contributors offer their analyses, including the Belfer Center's Mayumi Fukushima.

At the 2021 Shanghai Cooperation Organization (SCO) summit in Dushanbe, Tajikistan, the bloc announced the approval of Iran's longstanding bid for membership. The Islamic Republic has viewed its involvement in the organization as a means of bolstering external legitimacy, fostering security-oriented regionalism, and promoting the transition toward the so-called multipolar world order. The SCO, led by Russia and China, has served as a regime-preservation network by providing Iran with a source of solidarity against external pressure. Tehran's commitment to the normative order, sustained by the SCO's discourse of noninterference, sovereignty, and countering the “three evils”—terrorism, extremism, and separatism—has galvanized the organization's role as a common front against the imposition of liberal norms and challenges to regime security.

For months, evidence has accumulated that North Korea may be preparing its seventh nuclear explosive test. Continuous warnings by analysts and the media about this possibility are a sobering reminder that Pyongyang's continued pursuit of a larger nuclear arsenal remains a challenge for the Non-Proliferation Treaty and the nonproliferation regime. This continues to be the case even as the public and leaders around the world have largely shifted their attention to the nuclear dimensions of the war in Ukraine.

Nicole Grajewski writes that assessing the real benefits—and limits—of joining the so-called "anti-NATO" can help policymakers better understand what Tehran, China, Russia, and other participants are getting out of their summits.

Ambassador Thomas Graham Jr. and Mariana Budjeryn recount Taiwan's history which reveals the island democracy's resilience, as well as how — and why — the United States should reinforce its support.
