Fifty years after Apollo 11 astronauts first walked on the moon, the world is entering a new Space Age. Outer space, a domain once reserved for the great powers, is democratizing. New “space-faring” nations and private corporations are entering the final frontier, taking advantage of breakthrough technologies and lower financial barriers. The possibilities for humanity are immense. They include new opportunities for communication, for observing and understanding the Earth’s natural systems, for exploring the solar system and the heavens beyond, for exploiting space-based resources, and for constructing planetary defense systems to protect the planet from catastrophic collisions with near-Earth objects—asteroids, […]

Last week, the United Nations Intergovernmental Panel on Biodiversity and Ecosystem Services, or IPBES, put out a call to arms to save endangered species and ecosystems. The body’s report, titled “Global Assessment Report on Biodiversity and Ecosystem Services,” was based on the work of hundreds of scientists and thousands of scientific studies. It warned that no fewer than a million animal and plant species are at risk of extinction around the globe. “Biodiversity is declining faster than at any time in human history,” the report lamented—and humans are to blame. We have long taken the innumerable goods that nature provides […]

The pursuit of an open world, I wrote last week, animated U.S. postwar planning during President Franklin D. Roosevelt’s administration. The United States sought an international order based on collective security, nondiscriminatory commerce and political self-determination, governed by multilateral institutions. As an objective that promised to balance national sovereignty with common rules of coexistence, it was deeply in U.S. national interests. That same vision has never been more relevant than it is today, when the defining global struggle pits defenders of openness against forces of closure. Preserving an open world—as scholars Mira Rapp-Hooper and Rebecca Friedman Lissner have recently argued—should […]

The International Criminal Court in The Hague, Netherlands, Jan. 16, 2019 (AP photo by Peter Dejong).

In mid-April, a panel of judges at the International Criminal Court rejected Chief Prosecutor Fatou Bensouda’s request to open an investigation into war crimes and crimes against humanity that may have been committed during the long U.S. war in Afghanistan. Ahead of the decision, the Trump administration had waged an aggressive campaign against the case, which threatened to reveal atrocities committed by U.S. forces, including American troops and Central Intelligence Agency officials. Though the ICC judges acknowledged that war crimes and crimes against humanity were committed in Afghanistan, they determined that a successful investigation was not feasible. Essentially, they acknowledged […]
