 Ongoing political developments suggest that such debates are of more than narrow scholarly interest. Until recently, some of globalization’s key prongs seemed destined to transform human affairs in seemingly permanent ways: economic globalization, as well as the growth of a panoply of international and global political and legal institutions, continued to transpire at a rapid rate. Such institutional developments, it should be noted, were interpreted by some cosmopolitan theorists as broadly corroborating their overall normative aspirations. With the emergence of resurgent nationalist and populist political movements, many of which diffusely (and sometimes misleadingly) target elements of globalization, globalization’s future prospects seem increasingly uncertain. For example, with powerful political leaders regularly making disdainful remarks about the UN and EU, it seems unclear whether one of globalization’s most striking features, i.e., enhanced political and legal decision-making “beyond the nation state,” will continue unabated. Tragically perhaps, the failure to manage economic globalization so as to minimize avoidable inequalities and injustices has opened the door to a nationalist and populist backlash, with many people now ready to embrace politicians and movements promising to push back against “free trade,” relatively porous borders (for migrants and refugees), and other manifestations of globalization (Stiglitz 2018). Even if it seems unlikely that nationalists or populists can succeed in fully halting, let alone reversing, structural trends towards deterritorialization, intensified interconnectedness, and social acceleration, they may manage to reshape them in ways that cosmopolitans are likely to find alarming. Whether or not nationalists and populists can successfully respond to many fundamental global challenges (e.g., climate change or nuclear proliferation), however, remains far less likely.
