Nationalists today support [[national sovereignty]] and [[self-governance]] over [[globalism]], preserving their respective national cultures and demographics over [[multiculturalism]], and a [[border wall]]. [[Economic nationalism]] is a variant of nationalism that prioritizes a nation-state's economic independence. Nationalism has a strong association with [[limited government]], [[individual liberty]], and national cohesion.<ref name="Hazony2018">Hazony, Yoram (August 24, 2018).

Lack of nationalism, or a desire for new nations, was a cause for the split of countries such as [[Yugoslavia]] and [[Austria-Hungary]].

Examples of this negative nationalism are the [[Nazi Party]] in [[Germany]] (although it should be noted that the propaganda minister for the Nazis, Joseph Goebbels, when describing the Nazis as being of the German Left, said "we despise bourgeois nationalism."), the ethnic conflict in the former Yugoslavia, and the current isolationist policies of [[North Korea]]. The latter version, in particular, Nazi Germany, also led to nationalism being demonized to the extent that even having any pride for a country is considered evil, and the former was also considered bad due to the idea that nationalism causes wars. This interpretation was generally pushed by [[globalist]]s and [[Postmodernism|post-modernists]], and adherents of the [[Idea of Progress]].
