International Space Law Under the Trump Administration: Commerce and Security

Early themes of the second Trump administration's orientation toward international space law include military assertiveness, privatization, and nominal diplomatic engagement. These themes carry significant implications for international space law. They pressure longstanding international legal ambiguities, widen existing geopolitical divisions, and raise questions about how public-private interdependence will shape state responsibility and the development of norms in space. This essay was prepared for a special issue of the American Journal of International Law that offers an introduction and overview of the U.S. government's actions across a wide range of international legal issues in the first six months of President Trump's second term.
