How did the world respond to ultranationalism?

The world has responded to ultranationalism with a mix of concern and resistance, particularly in the wake of historical events such as World War II and the rise of authoritarian regimes. Many nations have sought to promote international cooperation, human rights, and multiculturalism as countermeasures, emphasizing the dangers of exclusionary ideologies. In contemporary politics, there are ongoing debates about nationalism and globalism, with some countries experiencing a resurgence of ultranationalist movements while others reinforce democratic values and inclusivity. International organizations and alliances often work to mitigate the effects of ultranationalism by fostering dialogue and collaboration among nations.
