International Security & Defense

This piece is a series in the Defense, Emerging Technology, and Strategy (DETS) Program’s analysis on the war in Ukraine, including a corresponding policy brief on Ukraine’s Battlefield Technologies and Lessons for the U.S. published in July 2023. 

Calder Walton says both seek to topple the United States from atop world stage, with China's blend of money, influence, all-hands-on-deck approach posing the greater threat.

Stephen Walt analyzes the priority that the United States should place on competing with China by asking and answering five questions.

Why should Washington save Intel? The answer most frequently provided by policymakers is that the U.S. produces no advanced chips, putting it at risk of losing a conflict with China if Taiwan is unable to ship chips across the Pacific. In reality, this is a canard. Peter Wennink, CEO of Dutch lithography giant ASML, dispelled this myth in December, saying that “it is common knowledge that chip technology for purely military applications is usually 10, 15 years old.” America’s warfighting capability is not meaningfully undermined by its lack of production of advanced chips as even platforms like the F-35 fighter jet use only legacy chips.

The half-century since the official demise of the Bretton Woods system of fixed exchange rates has shown the benefits of what replaced it. While some may feel nostalgic for the postwar monetary system, its collapse was inevitable, and what looked like failure has given rise to a remarkably resilient regime.

Last week, U.S. Sen. Joe Manchin seemingly dashed Democrats’ hopes for congressional action to slow climate change. Sen. Bernie Sanders accused Manchin of “sabotag[ing] the president’s agenda”; Rep. John Yarmuth, when asked about the consequences of Congress not acting on climate change, said, “We’re all going to die”; and climate activists, as well as some Democrats in Congress, wondered if Manchin should be removed as chair of the Senate Energy and Natural Resources Committee.

High broadband access and adoption rates can significantly improve earnings and net worth. Yet, year after year, Black and Brown Americans are among the most disparately impacted by digital inequities, which only contribute to the structural economic disparities that have tormented them for centuries. This tribute to Black History Month explains why historic investments in digital infrastructure are insufficient without transformational broadband policies that support economic resilience in every household.

Russia’s belligerence against Ukraine is underscoring once again the inextricable link between national security and energy security. Today, Russia is flexing its energy dominance over a dependent Europe. But tomorrow, the danger may come from China and its control over the raw materials that are key to a clean energy future.

The United States and its allies must ensure that doesn’t happen.

If you were wondering whether Europe is running out of options to deal with its continuing energy crisis, one of Britain’s largest energy suppliers just offered an answer.

Joseph Nye argues that prudence results from the fear of creating unintended consequences in unpredictable systems and can develop into a norm of nonuse or limited use of certain weapons or a norm of limiting targets. Something like this happened with nuclear weapons when the superpowers came close to the brink of nuclear war in 1962, during the Cuban missile crisis. The Limited Test Ban Treaty followed a year later.
