2020 dawns with the multilateral system in crisis. The next 12 months will determine whether the world is capable of controlling nuclear proliferation, arresting runaway climate change and restoring faith in the United Nations. Some pivotal events will shape success or failure in the coming year. Preserving the Nuclear Regime. Of the several potential catastrophic risks confronting humanity, the specter of nuclear war remains the most terrifying. Since the bombings of Hiroshima and Nagasaki in 1945, the world has escaped the horror of nuclear weapons. Much of the credit, beyond deterrence and plain dumb luck, goes to the Treaty on […]

Like many classic mystery stories, the Povl Bang-Jensen affair involved an agitated dog. The name and breed of the animal are not recorded.

Yet it soon became clear that something was amiss. The dog, […]

The United Nations’ annual climate conference opened in Madrid last week following an important if quiet milestone: the 60th anniversary of the Antarctic Treaty, one of the most successful yet least known multilateral agreements ever signed. At the height of the Cold War, the treaty froze several countries’ sovereignty claims to the polar South, while designating Antarctica a part of the global commons. Nations would not compete geopolitically over the continent but instead cooperate peacefully there in the name of science and environmental stewardship. Although fraying at the edges, the treaty remains a triumph by any measure. Unfortunately, for all […]
