The Summit for Democracy on December 9 and 10 brought together the heads of over 100 countries to discuss the state of political freedom around the world. Convened by President Biden, the Summit struck a somber tone, as participants grappled with the growing power of authoritarian states and the rising popularity of populist leaders within the democratic world. Michael Abramowitz, Ivo Daalder, Anders Fogh Rasmussen, and Nathalie Tocci consider the scale of the challenges raised at the Summit, and how the world’s democracies might respond.
