The War Against the West is a critical study of German National Socialism written by Aurel Kolnai and published in 1938. It describes German National Socialism as diametrically opposed to the [classical] liberal, democratic, Constitutional, and free-enterprise "Western" tendencies found mainly within Britain and the United States.

During the twenties and thirties, Kolnai, who converted to Catholicism under the influence of G.K. Chesterton, read extensively in the German language fascist and national socialist literature. The book compiles and critiques the anti-Enlightenment works of national socialist writers themselves. Kolnai's study was the first comprehensive survey in English of German national socialist ideology as a counter-revolution against what German thinkers saw as the materialistic, rootless civilizations dominated by comfort-addicted, money-and-security-centered, liberal bourgeois and rootless cosmopolitan Jews; the antithesis of the heroic model of more vital civilizations, prepared to risk their lives, to die for ostensibly "higher" ideals. Kolnai argues that national socialist ideology is not only alien to the West, but profoundly disturbing and dangerous.

Kolnai described the German national socialists' war against the West as, in essence, a war of paganism against Christian civilization. In citations from Hitler, Goebbels, and others, Kolnai sought to expose what he saw as "the obsessive German national socialist effort to replace Christianity with a crude and barbaric form of pagan religion, to twist the cross of Christ into a swastika."
