This week in Say More, Project Syndicate talks with Joseph S. Nye, Jr., an emeritus professor at Harvard Kennedy School, a former U.S. assistant secretary of defense, and the author, most recently, of A Life in the American Century.

Joseph Nye considers lessons from his own work on preventing the spread of nuclear technology in the 1970s.

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.

China has at least a 70% dependence on the U.S. and its allies for more than 400 items, ranging from luxury goods to raw materials needed for Chinese industries, a new analysis of trade data has found. (...) The analysis, set to publish Wednesday in the International Security academic journal, uses data from the United Nations Comtrade database, which tracks official global trade statistics. China’s high-dependency exposure was calculated by bundling together trade activity from the U.S. and more than a dozen allies across a range of categories.

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.

In the wake of the global financial crisis of 2008, China began to move away from the market-based approach that had shaped its economic policies for three decades, and toward something that might be termed "party-state capitalism," which involves a high degree of CC control over strategic sectors of the economy. This has led to significant changes in the U.S.-Chinese economic relationship, as both sides have made efforts to secure supply chains, screen inward and outward capital flows, diminish the power of global firms, and reorganize alliances to protect against economic coercion.

Stephen Walt argues that the true value of more diverse decision-making teams and more open political systems is not that they never make mistakes but rather that they make it more likely that policy blunders will be corrected once it is clear they are not working.

Of all the intractable issues that could spark a hot war between the United States and China, Taiwan is at the very top of the list. And the potential geopolitical consequences of such a war would be profound. Taiwan-"an unsinkable aircraft carrier and submarine tender," as U.S. Army General Douglas MacArthur once described it--has important, often underappreciated military value as a gateway to the Philippine Sea, a vital theater for defending Japan, the Philippines, and South Korea from possible Chinese coercion or attack.

States frequently acquire proof that other states have violated norms. Yet, existing theories do not fully explain how states wield such proof to coerce wrongdoers. Four case studies of nuclear proliferation probe a novel theory of how states coerce norm violators by concealing, sharing privately, or publicizing proof of guilt.

Wedge strategy theory explains how states use strategic arms control to divide adversaries by affecting their trust, threat perceptions, and beliefs about a commitment’s trade-offs. Examining three landmark arms control negotiations shows how the wedge motive was a key component to these negotiations.
