I write from a quiet, mountainous part of Central Europe. The scenery is idyllic, and the fall air is crisp.
But much as the case has been in my other recent trips to the European continent, the sights I see and the conversations I hear are all underscored by a similar haunting concern: Will there even be a Europe, in any cognizable sense of the term, a century from now?
All across the continent, fertility rates have plummeted, and the Christianity that defined the civilization for two millennia is viewed as a quaint relic of a bygone era.
The combination of modern European Union political and economic integration on the one hand, combined with imposed mass immigration from foreign (namely, Islamic) cultures on the other hand, has led to a place where sense of home and hearth is diminished — and along with it, community, meaning and purpose.
In Britain, two Jews were killed following a synagogue attack by a Syrian immigrant on the holiest day on the Jewish calendar. In Germany — yes, Germany — Jews have already been advised for years against wearing a kippah head covering in public.
More generally, Europeans' personal happiness levels have seemingly gravitated away from church and children, the traditional sources of meaning, and toward a discomfiting positive correlation with the size of a nation's welfare state.
The stunning Louvre museum heist earlier this week in Paris offers an uncanny encapsulation of the broader society-wide phenomenon.
On Sunday, thieves disguised as construction workers stole, during broad daylight, eight pieces of the French crown jewels estimated to be worth roughly $100 million.
And perhaps the most astonishing aspect of this real-life caper is this: As of this writing, the thieves have not been caught.
The utterly humiliating inability of French authorities to either prevent the theft of the literal crown jewels or promptly arrest the perpetrators after the fact is the most poetic possible way to demonstrate a point that has come up in so many of my conversations last week: At best, European political and cultural elites have no interest in protecting and preserving their culture; and at worst, they have an interest in seeing that culture replaced root and branch.
Back home in the United States, the situation is in some ways not so different.
It was concern about decades of reckless American immigration policy and elite-driven cultural decadence, above all, that first propelled Donald Trump to the White House in 2016.
The chief difference in this respect between the United States and Europe, besides America's more robust (if still declining) church, is thus primarily a political one.
Trump is now a two-term president, whereas the only major European country to have a right-of-center leader today is Italy. Viktor Orban of Hungary can't do it all by himself.
Amidst the prevailing transatlantic cultural currents of nihilism, childlessness and general dissatisfaction, it has never been more important that political leaders offer a robust defense of their respective homelands and a compelling vision for those homelands' future.
Sincerity of religious conviction and the utilitarian value of religious community are both time-tested ways of offering meaning and stability in a person's life, but there is a role to be played by an anodyne nationalism as well.
Following religious conviction, pride in one's homeland and confidence in its future is the sentiment that very well might induce the most people to get married and have children.
If one hates his country and thinks it is evil, or even if he merely thinks the future of his country looks positively dire, he might well be less inclined to make the tremendous investment of bringing new life into the world. What's the point, one might well conclude, of raising children in a hellish, dystopian future?
Trump's political success is partially due to his keen understanding of this very phenomenon. One can always quibble on the merits or demerits of a certain policy approach, but Trump's signature "Make America Great Again" (MAGA) tagline grasps at an ineluctable truth: America, for various reasons, had been in decline, but the man in charge now understands that and plans to turn things around.
Across Europe, there is much that can be learned from the Trump example.
But that begins with evincing a simple desire to defend the existence and perpetuity of one's culture.
It begins with a meaningful determination to prolong the lifespan of a particular nation, in Edmund Burke's famous sense of the term, as a social compact between the dead, the living and the yet unborn.
In Paris, perhaps it begins by defending the nation's literal crown jewels.
Surely that isn't too much to ask for, is it?
