Science, Technology, and Public Policy

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.

This policy brief explains how Russia and Iran have sought to upgrade their partnership through greater diplomatic support for pushing back on Western hegemony, mutual provision of key weapons systems, and sharing of expertise on evading sanctions.

Belfer Center experts on security, intelligence, and cybersecurity issues were interviewed on the recent leak of classified military intelligence documents allegedly by Airman Jack Teixeira.

David M. Allison argues that in ascending order of predictive power, warnings of an imminent nuclear strike would come from Russian whistleblowers, the U.S. intelligence community, and Putin himself.

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.

To accelerate the global transition to a low-carbon economy, all energy systems must be actively decarbonized. While hydrogen has been a staple in the energy and chemical industries for decades, clean hydrogen – defined as hydrogen produced from water electrolysis with zero-carbon electricity – has captured increasing political and business momentum as a versatile and sustainable energy carrier in the future carbon-free energy puzzle.

No great breakthroughs or dramatic developments were expected at the Biden-Putin summit, and none was achieved. But the message was clear: There is a new sheriff in town. Putin noticed, describing Biden as very different from Trump—experienced, balanced, and professional.

Bruce Schneier and Tarah Wheeler describe the future of war as cyberwar. They advise that if weapons and systems aren't secure, don't even bother bringing them onto the battlefield.

Tarah Wheeler critiques a new book, This Is How They Tell Me The World Ends by Nicola Perlroth, and concludes that it gets the policy recommendations right while making technical errors that could undermine trust in its conclusions.

Bruce Schneier recommends that the United States improve government software procurement. Scrutiny cannot end with purchase: Security requirements need to be monitored throughout the software's life cycle, along with what software is being used in government networks.
