Dostoyevsky made mistake about one thing - nihilism of the West. If the West was really nihilistic, we had never had all that problems with the West. West is obsessed with their supremacy, and truly and sincere believe things could be only in a way they understand. That is why they constantly try to push their "values" on us. This is not nihilism, but more like religion or cult. West uses nihilism as a weapon to break the will of other nations, but they are in no way nihilists themselves.

Ultimately liberalism leads to nihilism because it's relativistic which leads it to rejecting absolute and objective truth. A system gets more consistent with its basic presuppositions with time and the logical conclusion to classical liberalism of the time of the Enlightenment is playing out in the troons movement and the inability to recognize basic metaphysical categories like biological sex, the rejection of all inherent purpose and meaning to things, of objective morality and of metaphysics itself.

Fr. Seraphim Rose wrote about it in his great book Nihilism: The Root of the Revolution of the Modern Age and he too refers to Dostoyevsky there. I'd argue the West today is nihilistic and is destroying itself which is evident by the many crises it suffers but most of all the demographic one and the ubiquitous normalization of degeneracy. This is a sure sign of civilizational collapse as historians like Spengler have observed.
