Oddly enough, I know of a far-ideology that, like Posadism, celebrates nuclear war as a kind of hard reset for society that would allow them to flourish. It's called American futurism, and it was born from the infamous IronMarch forum (the birthplace of the Atomwaffen Division terrorist group) before they got shut down. On RationalWiki's page covering IronMarch , I wrote virtually the entire section detailing American futurism and what it believed.To sum up, while American futurism is unquestionably rooted in fascism and neo-Nazism, it breaks from such in one very important area. You see, a big part of fascism is its obsession with tradition and getting back to the foundational values of the nation, before they were corrupted by the forces of liberalism, socialism, and modernity... but in an American context, you run into a problem. The foundational values of the US were those of the Founding Fathers, who were all heavily informed by 18th century Enlightenment liberalism. The society that Americans live in today flows directly from what they built. And so, the goals of destroying liberalism and returning to the old ways are fundamentally at odds, because liberalismthe "old ways" in the US, having prevented a true "blood and soil" nationalism from taking root and instead assembling the American people from a hodgepodge of different ethnic and cultural groups all bound together by civic nationalism and common values rather than common blood.Some conservatives who wish to overturn American liberalism engage in historical revisionism to support their goal, claiming (on spurious grounds) that the Founding Fathers were actually fundamentalist Christians as we would understand the term today, and that their intent was to build a nation rooted in biblical Christianity. The American futurists reject this line of thought entirely. For them, the very existence of the United States, its culture, its government, its constitution, and its entire way of life is an abomination that goes against all natural law, a national artificially constructed by intellectuals and imposed on a rootless people without their own ethnic traditions to draw from for resistance -- in short, the prototype for what many conspiracy theorists (often an overlapping group with this crowd) believes that the "New World Order" has in store for the entire world. Furthermore, since these roots, unlike those of the USSR (which was built atop the foundation of Russia), run to the very core of the nation, that means that everything must be torn down and destroyed in order to save the white race. Trying to prove that it's actually Christian would, for some of them, only prove their point, since many of them see Christianity itself as a Middle Eastern religion that suppressed the true pagan spirituality of the European people, one whose precepts merely set the stage for the rise of liberalism. In short, while fascism is a counter-revolutionary ideology, American futurism is a purely revolutionary one, believing itself to be building something new atop the ashes of the old rather than restoring something old and pushing back the new.Needless to say, a lot of them believe that nuclear war is the perfect way to accomplish this. It's where the Atomwaffen Division got their name from, even. Their idea of what to replace America with often comes back to fetishization of the frontier, believing it to be a place where ideals of "blood and soil" could have taken root if only they had been allowed to, and that, since there is no frontier left in the US, the apocalypse would make for a great way to open up new frontiers and bring their dreams to life. Much like the original Italian futurists, they celebrate violence and war for their own sake rather than just as a means to an end, seeing them as invigorating, masculine enterprises and themselves as future warlords in the post-apocalyptic wasteland who will build new nations rooted in white supremacy.
