Which ideology is characterized by ultranationalism, dictatorship, and imperialism?

Fascism is characterized by ultranationalism, dictatorship, and imperialism, making it the correct choice for this question. This ideology emphasizes the importance of the nation or race above the individual and often features a centralized authority led by a dictator.

Under fascist regimes, the state is considered supreme, and there is a strong focus on national strength and unity, often at the expense of individual rights and freedoms. Fascism promotes the idea that the nation is in a state of conflict with other nations, leading to militaristic and imperialistic ambitions where expansion and dominance over others are sought.

In contrast, communism seeks to establish a classless society and abolishes private ownership, which does not align with the characteristics described in the question. Libertarianism champions individual freedom and minimal state intervention, which is fundamentally opposed to the centralized control found in fascism. Socialism, while it does advocate for state involvement in the economy and social welfare, does not inherently endorse ultranationalism or dictatorship in the way fascism does.
