Secretary of State Marco Rubio delivered a pointed message to European allies on Friday: their embrace of mass migration and restrictions on fundamental liberties threatens the very foundation of the Western alliance.

Speaking at a State Department briefing, Rubio defended the Trump administration’s National Security Strategy memo, which warned that Europe faces “civilizational erasure” if current globalist policies continue unchecked. The assessment has predictably triggered outrage among European elites, with German Chancellor Friedrich Merz declaring portions of the document “unacceptable” and European Commission President Ursula von der Leyen demanding the United States refrain from “interfering” in European democracy.

Here are the facts: von der Leyen is an unelected bureaucrat lecturing the United States about democracy. The irony is apparently lost on her.

Rubio refused to back down from the administration’s assessment, presenting a logical argument that should concern anyone invested in the transatlantic relationship. “You go to these NATO meetings and you meet with people, what they will tell you our shared history, our shared legacy, our shared values, our shared priorities,” Rubio explained. “Well, if you erase your shared history, your shared culture, your shared ideology, your shared priorities, your shared principles, then what – then you just have a straight-up defense agreement. That’s all you have.”

This is not complicated. The Western alliance was never merely a military pact. It was built on shared principles: liberty, individualism, self-governance. These are not abstract concepts. They are the bedrock values that distinguish Western civilization from authoritarian alternatives. The United States was founded on these Western values, many of which originated in the very European nations now abandoning them in favor of multiculturalism and speech codes.

Rubio noted that the Trump administration remains “concerned that, particularly in parts of Western Europe, those things that underpin our alliance and our tie to them could be under threat in the long term.” He added that numerous European leaders recognize this crisis privately, even if they lack the political courage to say so publicly. Leaders in Eastern and Southern Europe, notably, are far more willing to acknowledge reality.

The Secretary specifically addressed mass migration, citing the recent Islamist terror attack at a Jewish Hanukkah celebration on Bondi Beach in Australia as evidence of the broader challenge facing Western nations. “Mass migration over the last decade has been highly disruptive, not just to the United States but also to continental Europe and in some cases in the Indo-Pacific as well,” Rubio said.

He drew a crucial distinction between controlled immigration and mass migration. The latter, he argued, is inherently destructive because “it’s very difficult for any society to absorb and assume hundreds of thousands if not millions of people over a short period of time, especially if they come from halfway around the world.”

This is basic logic. Successful immigration requires assimilation, which requires time, cultural compatibility, and commitment from both immigrants and host nations. Mass migration by definition prevents this process. When millions arrive rapidly from cultures with fundamentally different values, social cohesion breaks down. European leaders have spent years denying this reality while their citizens live with the consequences.

The question facing Europe is straightforward: will it defend the principles that made Western civilization the most prosperous and free in human history, or will it continue down a path of cultural self-destruction? The Trump administration is simply stating what millions of Europeans already know but their leaders refuse to admit.

If European elites find this message unacceptable, perhaps they should examine why their own citizens increasingly agree with it.
