Joseph Nye considers lessons from his own work on preventing the spread of nuclear technology in the 1970s.

This year's G7 summit in Hiroshima sees nuclear disarmament and non-proliferation sitting high on the agenda, amid rising tensions between the nuclear states and an increasingly divided international order.  Six contributors offer their analyses, including the Belfer Center's Mayumi Fukushima.

According to the "Madman Theory" outlined by Daniel Ellsberg and Thomas C.

 Stephen Walt decided to look back to see if 2022 had gone according to his expectations. In his last column of 2021, he had described "Biden’s 2022 Foreign-Policy To-Do List." What did he get right, what did he get wrong, and how well did the Biden administration perform?

In light of Russia’s annexation of Crimea and its current threat to Ukrainian sovereignty, it’s fair to ask: What is the significance now of the Budapest Memorandum?

But declining powers merit as much diplomatic attention as rising ones do. Joseph S. Nye worries that the United States lacks a strategy to prevent Russia from becoming an international spoiler.

Stephen Walt writes that getting a new nuclear deal with Iran won't be easy—but the U.S. president's utter lack of principle could help guide the way.
