Stephen Walt offers some brief foreign-policy advice for the newest members of the U.S. legislature.

Ivan Arreguin-Toft analyzes the West's information technology asymmetry of capability, which has given way to asymmetry of vulnerability. While democracies worldwide remain threatened, they also contain the means to restore themselves.

Hostile foreign states are using weaponized information to attack the United States. Russia and China are disseminating disinformation about domestic U.S. race relations and COVID-19 to undermine and discredit the U.S. government. These information warfare attacks, which threaten U.S. national security, may seem new, but they are not. Using an applied history methodology and a wealth of previously classified archival records, this article uses two case studies to reveal how and why a hostile foreign state, the Soviet Union, targeted America with similar disinformation in the past

Ivan Arreguin-Toft argues that non-material considerations like cyber power matter just as much as material ones in debates about U.S. retrenchment from the Middle East.

Joseph Nye writes that even at this early stage, there are at least eight lessons— some old, some new— that the world is learning (or relearning) from the war in Ukraine.

Will China succeed in what some call its grand strategy of displacing American power? Whichever scenario emerges also depends on the strategy the US chooses in response, rites Joseph Nye.

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.

The powerful effects of artificial intelligence are already being felt in business, politics, medicine, war, and almost every other domain of twenty-first century life. For all of its positive potential, the technology presents significant risks that are best addressed sooner rather than later.

In the wake of a series of damaging cyber intrusions on private businesses controlling critical pieces of U.S. infrastructure, Harvard Kennedy School Senior Lecturer Juliette Kayyem says that countering the growing threat will require erasing the "legal fiction" that cyberattacks are different than physical attacks on American civilians.

Even if formal cybersecurity treaties are unworkable, it may still be possible to set limits on certain types of civilian targets, and to negotiate rough rules of the road. Whether U.S. President Joe Biden succeeded in launching such a process at his meeting last month with Russian President Vladimir Putin may become clear soon.
