International Security & Defense

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. 

Mohammad Tabaar argues that the attacks on Red Sea ships unintentionally advance the Houthis agenda by allowing it to claim that it is fighting imperialism, and the attacks help Iran by fortifying its political foothold in the Middle East. Washington should therefore cease the strikes. It should, instead, work to halt the war in Gaza. The United States should also try to strengthen the region's diplomatic agreements and shore up its security framework. Otherwise, the Houthi-Iranian partnership will only grow stronger, as will Tehran's leverage in the region.

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.

Juliette Kayyem argues that the sooner President Joe Biden acknowledges that the United States will likely be drawn into a fight to protect shipping traffic through the Suez Canal, the more time the U.S. military has to plan, and the less severe the harm will be to the global economy.

Joseph Nye writes that Washington's strategy towards Beijing should be to avoid either a hot or cold war, co-operate when possible and marshal its assets to shape China's external behaviour. This can be done through deterrence and a strengthening of both alliances and international institutions.

Power transitions affect a state’s ability to exercise economic statecraft. As a dominating and a rising power approach parity, they face structural incentives to decouple their economies. This decoupling affects business-state relations: high-value businesses within the dominant power tend to oppose their state’s economic statecraft because of its costs to them, whereas low-value businesses within the rising power tend to cooperate because they gain from it. 

On October 30, 2023, President Biden issued the Executive Order on the Safe, Secure, and Trustworthy Development and Use of Artificial Intelligence, aimed at realizing the benefits of AI, while mitigating critical risks. This article provides an overview of its key national security initiatives and explores issues relevant to implementation.

For Ukraine to maintain its defense and decisively thwart Russia’s invasion, it will take steadfast commitments from Western allies providing both state-of-the-art equipment and basic warfighting needs, local industry leaders and factory workers readying equipment for the frontlines and developing innovative technologies, and civilian volunteers tirelessly filling in the remaining gaps.

Joseph Nye writes that if the United States maintains its alliances, invests in itself, and avoids unnecessary provocations, it can reduce the probability of falling into either a cold war or a hot war with China. But to formulate an effective strategy, it will have to eschew familiar but misleading historical analogies.
