Calder Walton, Ernest May Fellow in History and Policy and editor of a three-volume series on espionage, provides context for the FBI's Russia probe

The Harvard Gazette's Christina Pazzanese interviews Belfer Center Senior Fellow James Clapper his new book, and the state of U.S. intelligence. 

The fall of Aleppo is a human catastrophe. It’s also a demonstration of the perils of choosing the middle course in a military conflict. Sometimes it’s possible to talk and fight at the same time. But in Syria, the U.S. decision to pursue a dual-track, halfway approach made the mayhem worse.

We urge the next president to establish a White House Council of Historical Advisers. Historians made similar recommendations to Presidents Carter and Reagan during their administrations, but nothing ever came of these proposals. Operationally, the Council of Historical Advisers would mirror the Council of Economic Advisers, established after World War II. A chair and two additional members would be appointed by the president to full-time positions, and respond to assignments from him or her. They would be supported by a small professional staff and would be part of the Executive Office of the President.

The defining question about global order for this generation is whether China and the United States can escape Thucydides’s Trap. The Greek historian’s metaphor reminds us of the attendant dangers when a rising power rivals a ruling power—as Athens challenged Sparta in ancient Greece, or as Germany did Britain a century ago. Most such contests have ended badly, often for both nations, a team of mine at the Harvard Belfer Center for Science and International Affairs has concluded after analyzing the historical record. In 12 of 16 cases over the past 500 years, the result was war. When the parties avoided war, it required huge, painful adjustments in attitudes and actions on the part not just of the challenger but also the challenged.

Joel Brenner responds to Jon R. Lindsay's winter 2014/15 International Security article, "The Impact of China on Cybersecurity: Fiction and Friction."

Jon R. Lindsay responds to Lucas Kello's fall 2013 International Security article, "The Meaning of the Cyber Revolution: Perils to Theory and Statecraft."

Cyberwar has been described as a revolution in military affairs capable of overturning the prevailing world order. By itself, however, cyberwar can achieve neither conquest nor, in most cases, coercion. Conflict over the internet is much more likely to serve as an adjunct to, rather than a substitute for, existing modes of terrestrial force, and to augment the advantages of status quo powers rather than threatening existing political hierarchies.

While decisionmakers warn about the cyber threat constantly, there is little systematic analysis of the issue from an international security studies perspective. Cyberweapons are expanding the range of possible harm between the concepts of war and peace, and give rise to enormous defense complications and dangers to strategic stability. It is detrimental to the intellectual progress and policy relevance of the security studies field to continue to avoid the cyber revolution's central questions.
