What happens when Nationalism gets out of control?

When nationalism becomes extreme, it can lead to xenophobia, discrimination, and violence against perceived outsiders or minority groups. This unchecked fervor often results in conflict, as nations may prioritize their interests over global cooperation, potentially igniting wars or severe diplomatic tensions. Additionally, extreme nationalism can undermine democratic values and human rights, fostering authoritarian regimes that suppress dissent and promote a singular national identity. Ultimately, the consequences can destabilize societies and create deep divisions both domestically and internationally.
