False claims to scientific authority were used to advance the American and British war on terror. In popular rhetoric, President George W. Bush borrowed (and distorted) one of the most influential theses of political science, the claim that democracies do not fight with one another. Bush also named prominent political scientists, including Francis Fukuyama—who claimed history had reached its culmination in liberal democracies—to prominent advisory positions in government. In addition, other prominent social scientists, such as Samuel Huntington, provided alternative social scientific justifications for the war on terror and later nationalistic public policy that relied on creating permanent outsider identities for Muslims and Latinos. Scientism helped American and British citizens imagine that their use of military violence was fully rational and objectively justified as the war on terror turned into the rise of ultranationalism.
