I am skeptical that the US is inevitably going to collapse. It will continue to decline as a civilization and as a culture, and that decline will eventually lead to it losing its global empire. But the system is not automatically doomed due to demographics alone. The minorities that are growing are not Muslims or Africans, but Latin Americans and Asians, who are mostly capable of integrating into the Judeo-liberal society and will also tend to be "whitened" over time if miscegenation continues. The future US population might look like Argentines added a ~15 percent of negroes, with working-class whites in the more diverse states being gradually turned into castizos by mixing with Hispanics and Asians. Maybe something akin to Brazil, but with a White-Asian-Jewish ruling class instead of a Southern European one, so in reality much worse.

From a racialist perspective, this is of course a nightmare scenario, but it doesn't automatically spell doom to the liberal order in America. Europe is in a much different situation since our minorities for the most part either Moslems or actual savages, and traditionalism is much stronger here as well.

White America can only be saved through a mass racial awakening, middle and working-class whites must segregate themselves or they will be swallowed by the rising brown tide.
