Stephen Walt writes that those who favor foreign policy restraint believe the United States should trade and invest in other countries, encourage other states to do the same, and be open to managed immigration instead of building walls in a fit of xenophobia.

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 writes: So if some political leader came to me for advice or wanted to know what I thought about some foreign-policy maneuver they were contemplating, I'd ask them if they took nationalism into account, and I'd remind them of what happens when major powers ignore it.

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.

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.

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.

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.

Stephen Walt looks back at the Trump administration as four years of big ambitions, a handful of successes—and many more failures. He concludes that it was more than a missed opportunity because Trump's blunders have left the United States in much worse shape than when he took office. 

Stephen Walt describes how the United States' rise was fueled by fortunate circumstances that seem unlikely to last much longer. He lists four reasons why the country's luck just might be running out.
