In an extraordinary move, the Trump administration has formally embedded a racist conspiracy theory into the core of American foreign policy. The newly released 2025 National Security Strategy declares that Europe is facing "civilisation erasure," a claim that directly echoes the baseless "Great Replacement Theory" popular among far-right extremists.
From Fringe Theory to Official US Policy
The document, published on Friday 5 December 2025, asserts that "over the long term, it is more than plausible that within a few decades at the latest, certain Nato members will become majority non-European." This assertion is starkly at odds with all mainstream demographic analysis. The terminology and concept are lifted directly from the conspiracy theory coined by French writer Renaud Camus, which falsely alleges a global plot to replace white European populations.
This theory has found a powerful following among far-right groups, QAnon adherents, and Donald Trump's MAGA supporters. Its elevation to official US doctrine marks a profound shift, framing America's future relationship with Europe and the Anglosphere through a lens of racial paranoia.
A Blueprint for Intervention and Alignment
The strategy outlines a plan for the US to actively intervene in European affairs. It states America will "oppose elite-driven, anti-democratic restrictions on core liberties" among allies, a stance directly targeting European regulatory efforts like the Digital Services Act.
The White House has framed European attempts to regulate US tech giants like Meta, Apple, and Google—forcing them to moderate harmful content and disinformation—as acts of "censorship." The new doctrine pledges support for political groups in Europe that align with this American worldview, explicitly praising "the growing influence of patriotic European parties."
Vice President JD Vance is believed to be the primary architect of this doctrine, having previewed its themes during his first official trip to Europe in February 2025, where he launched startling attacks on NATO and European democracy.
The Putin Connection and Undermining Ukraine
The strategy's other clear influence is Vladimir Putin's Russia, a regime that has become a beacon for the international far-right. Putin's championing of "traditional" white Christian values dovetails perfectly with the Great Replacement narrative.
The document solidifies Trump's pro-Russia stance, justifying the cessation of all military aid to Ukraine except intelligence support. It controversially claims that "a large European majority wants peace, yet that desire is not translated into policy, in large measure because of those governments’ subversion of democratic processes," directly challenging the legitimacy of Ukraine's democratically elected government under Volodymyr Zelensky.
This alignment with Kremlin objectives seeks to amplify disinformation and fracture Western unity, building on prior successes like Brexit and Trump's own re-election.
With this strategy, the Trump administration has not only endorsed a dangerous conspiracy but has made it the foundation for confronting its closest allies. The document represents a copper-plated commitment to a worldview that undermines democratic norms, empowers extremist movements, and redefines America not as a traditional ally, but as a source of division and instability within the Western world.
