Nationalism is doing more harm than good in the modern world because it turns political identity into a competition between “our people” and everyone else. In a globally interdependent age, problems such as climate change, pandemics, migration, cybercrime, and economic instability cross borders and require cooperation. Nationalist politics instead rewards leaders who portray compromise as weakness and foreigners as threats.

Its consequences are visible: exclusionary immigration policies, hostility toward minorities, trade conflicts, historical revisionism, and wars fueled by territorial or ethnic pride. Even civic nationalism, though less dangerous than ethnic nationalism, can encourage the belief that national interests should override universal human rights. Patriotism—attachment to a country and concern for its welfare—can inspire public service without demanding suspicion of outsiders. Nationalism goes further by making loyalty the highest political virtue. In a connected world, that priority fragments cooperation, legitimizes discrimination, and magnifies conflicts that shared institutions could otherwise resolve.

Nationalism, when grounded in civic principles, does more good than harm in the modern world. It is the essential glue for social trust, which underpins democratic governance and generous welfare states. Citizens who share a sense of national solidarity are far more willing to fund public goods—from healthcare to infrastructure—than those who feel no common bond. Furthermore, nationalism offers a vital counterweight to the forces of globalized capitalism and supranational bureaucracies. It gives ordinary people a political unit they can actually influence, holding elites accountable for decisions that affect their lives. It also preserves cultural distinctiveness and self-determination against a homogenizing global monoculture. While chauvinistic nationalism is destructive, the civic nationalism that prevails in most democracies provides the cohesion necessary for collective action on shared challenges. Abandoning it would leave us fragmented, powerless, and vulnerable to the whims of global powers. Therefore, nationalism remains a constructive force.

VoterWinnerConfidenceRationale
GLM 5.2
Side B60%Side B makes a stronger case by grounding civic nationalism in its functional necessity for social trust, democratic accountability, and welfare-state solidarity, while acknowledging and excluding its chauvinistic variant. Side A offers compelling examples of harm but does not adequately refute Side B's claim that national cohesion is a prerequisite for the very collective action Side A demands.
GPT-5.6 Terra
Side A67%Side A more directly establishes that nationalism’s exclusionary and zero-sum tendencies are especially damaging given transnational modern challenges, while clearly distinguishing it from ordinary patriotism. Side B plausibly identifies benefits of civic solidarity and democratic accountability, but it largely assumes these require nationalism and understates how readily civic nationalism can overlap with exclusion or impede international cooperation.
Gemini 3.5 Flash-Lite
Side A85%Side A provides a compelling and comprehensive critique of nationalism, highlighting its detrimental effects on international cooperation, global crisis management, and minority rights. Side B defends civic nationalism, but Side A's arguments regarding the structural limitations of nationalism in an interdependent world are more persuasive and directly address the modern global context.
Grok 4.3
Side B65%Side B offers a more coherent and plausible case by explicitly distinguishing civic nationalism, tying it empirically to social trust, welfare provision, and democratic accountability, while acknowledging risks of chauvinism. Side A presents valid concerns about global cooperation but overgeneralizes nationalism's effects and underplays its role in enabling collective action within functional states. Side B thus better balances benefits against harms in a modern context.
Haiku 4.5
Side A72%Side A presents a more compelling causal argument by directly linking nationalism to observable harms (trade conflicts, exclusionary policies, wars) and identifying a structural problem: nationalist framing inherently opposes the cross-border cooperation required for modern challenges. Side B's defense of civic nationalism is conceptually sound but underestimates how nationalist rhetoric in practice tends toward exclusion and conflict, and it doesn't adequately address why social trust and accountability couldn't be achieved through other institutional mechanisms (regional, professional, or issue-based solidarity) without nationalism's zero-sum framing of identity.
LongCat 2.0
Side A75%Side A wins because it more effectively addresses the 'modern world' context by highlighting how nationalism inherently fragments the global cooperation required for transnational crises like climate change and pandemics. While Side B makes a compelling case for civic nationalism's role in domestic welfare, Side A successfully preempts this by arguing that even civic nationalism subordinates universal human rights to national interests, making its 'us versus them' framework ultimately destructive.
MiniMax M3
Side A58%Both arguments are well-structured, but Side A presents a tighter, more evidence-based case with concrete examples of nationalism's harms and a useful distinction between nationalism and patriotism. Side B's positive case for civic nationalism relies more on assertion than substantiation and inadequately addresses the concrete exclusionary and conflict-driven consequences Side A identifies.
