Science, Technology, and Public Policy

Joseph Nye argues hat the major threat to U.S. power comes from its internal divisions. These are serious liabilities but they were not created by the invasion of Ukraine.

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.

This week in Say More, PS talks with Joseph S. Nye, Jr., a professor at Harvard University.

Why would a state that lacks nuclear weapons choose to fight a state that has them? In this roundtable, four scholars evaluate Paul Avey's explanation for this phenomenon.

If Joe Biden defeats Donald Trump in November, the question he will face is not whether to restore the liberal international order. It is whether the United States can work with an inner core of allies to promote democracy and human rights while cooperating with a broader set of states to manage the rules-based international institutions needed to face transnational threats.

Polls in the United States and nine allied countries in Europe and Asia show that public support for a nuclear test is very low. If the Trump administration conducts a test, then it shouldn't expect backing from Americans or its closest U.S. partners.
