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.

Kelly Sims Gallagher asserts that politicians' pledges of dramatic long-term reductions should not let them off the hook for their failure to achieve more modest progress in the short term.

The Biden-Putin summit in Geneva did not disappoint the very low expectations set out for it. To move beyond symbolism and signaling, however, the Biden-Putin proclamation has to be translated into practical progress.

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.

There is an urgent need to incorporate the latest science on carbon emissions from permafrost thaw and northern wildfires into international consideration of how much more aggressively societal emissions must be reduced to address the global climate crisis.

Mariana Budjeryn argues that Ukraine should stand firm with its nuclear disarmament decision despite the violation of the Budapest Memorandum. The West, for its part, must reward this posture with unwavering support, communicating that Ukraine did the right thing. Instead of disparaging the Budapest Memorandum, Ukraine should use it as a framework to build a strong strategic partnership with the United States and its allies.

In the authors' view, neither formal NATO membership nor nuclear weapons are fitting security options for Ukraine in the face of Russian aggression. To secure its borders and achieve sustainable peace and stability in Europe, Ukraine should forge a treaty-based strategic alliance directly with the United States.

The Icelandic Ministry for Foreign Affairs recently published an extensive report with a detailed analysis on the current relationship between Greenland and Iceland with 99 recommendations on how to strengthen their co-operation. Halla Hrund Logadóttir moderated the discussion.

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.
