Nuclear Issues

Europe after the Russo-Ukrainian War must develop a new security structure to defend against any Russian aggression. The safest option is a non-offensive, confidence-building defense. This option includes proposals such as the “spider in the web” strategy and the “porcupine” strategy to provide for European security in a region threatened by Russian expansion—without relying on the threat of nuclear war. 

In this Q&A, Joseph S. Nye talks about his advice for the interim and future president of Harvard in the wake of Claudine Gay's resignation, which countries should be highest on our radar to prevent the threat of nuclear war, what role the U.S. should play in the Russia-Ukraine war, the significance of U.S. alliances in the Middle East, and more.

Mina Pollmann explains that between China and North Korea, the logic for increased Japan-South Korea cooperation is clear. All that was lacking was political will. 

Belfer Center experts on the U.S.-China relationship and Middle East issues shared thoughts on the significance of the unexpected Iran-Saudi Arabia agreement brokered by China. 

The costly Ground-based Midcourse Defense system remains unproven and unreliable in deterring North Korea’s threat to use intercontinental ballistic missiles. An airborne boost-phase intercept system may offer an alternative defense against North Korea without threatening Russian or Chinese deterrents.

Stephan Walt writes that Trump's foreign-policy instincts might be more sound—but he has forfeited the chance to lead.

The existing global political-economic order has been ruptured by the rise of China, a broad backlash against globalization, uncertainties about the U.S. commitment to a rules-based system, and most recently, the Covid-19 pandemic. What form(s) might a future world order take, and what principles should guide efforts to construct it? The Future World Order event series will address these questions by examining individual topics ranging from traditional security issues such as arms control to newer, relevant issues such as digital trade. Professors Dani Rodrik and  Stephen M. Walt will moderate individual sessions.

Why would a state that lacks nuclear weapons choose to fight a state that has them? In this roundtable, four scholars evaluate Paul Avey's explanation for this phenomenon.

Despite the far-reaching effects of the current pandemic,  the essential nature of world politics will not be transformed. The territorial state will remain the basic building-block of international affairs, nationalism will remain a powerful political force, and the major powers will continue to compete for influence in myriad ways. Global institutions, transnational networks, and assorted non-state actors will still play important roles, of course, but the present crisis will not produce a dramatic and enduring increase in global governance or significantly higher levels of international cooperation. In short, the post-COVID-19 world will be less open, less free, less prosperous, and more competitive than the world many people expected to emerge only a few years ago.

The 2018 National Defense Strategy (NDS) is predicated on a single organizing principle: America’s military pre-eminence is rapidly eroding. This is not a new concept. For years, experts have warned that the economic and technological advancements of U.S. adversaries, coupled with the 2008 financial crisis and America’s focus on peripheral conflicts, have caused a decline in America’s military dominance. 

In this context, the advances of near-peer competitors such as China and Russia have created plausible “theories of victory” in potential conflicts across Eastern Europe and East Asia. Competitors’ unaddressed improvements in strategic innovation, economic investment, and dual-use technology increases the risk of conflict and strains the U.S. alliance system. It is urgent that the United States reestablish and maintain credible deterrents against these near-peer competitors. After decades of focusing on post-Cold War ‘shaping’ operations, the American military needs to reinvigorate for full spectrum great power competition.

This report is intended as a blueprint on how to begin that process from graduate students at the Belfer Center for Science and International Affairs at Harvard University. Contained inside are 12 memorandums. Each provides a high-level overview and specific recommendations on a key issue of American defense policy.
