Following Britain's decision to leave the European Union and the election of Donald Trump as President of the United States in 2016, Fukuyama feared for the future of liberal democracy in the face of resurgent populism, and the rise of a "post-fact world", saying that "twenty five years ago, I didn't have a sense or a theory about how democracies can go backward. And I think they clearly can." He warned that America's political rot was infecting the world order to the point where it "could be as big as the Soviet collapse". Fukuyama also highlighted Russia's interference in the Brexit referendum and 2016 U.S. elections.
