Anti-nationalism is a political ideology that opposes nationalism, which is the belief in prioritizing the interests and culture of one's nation above others. Anti-nationalists argue that nationalism can lead to division, conflict, and exclusion, promoting instead a more global or cosmopolitan perspective that values cooperation among different nations and cultures. This ideology often emphasizes human rights, social justice, and environmental concerns over national interests. Anti-nationalists may advocate for international organizations, such as the United Nations, to address global issues collectively, rather than through the lens of individual nations.
