If you had to name the single costliest assumption the West made over the last decade, it wouldn't be a policy or a war or a trade deal: it would be a belief, quietly held across nearly every institution that mattered, that everyone else on the planet secretly wanted to become like it. Not just wanted its wealth or its stability, which is a far more defensible claim, but wanted its actual values: its particular commitment to openness, to integration, to a world where borders mattered less every year than the one before, as though liberal universalism were less a specific civilizational project and more a natural endpoint that any sufficiently modern society would eventually arrive at on its own.
That assumption was wrong.
And the cost of being wrong about it has been very real. If you genuinely believe the whole world shares your terminal values, then mass migration doesn't need a plan attached to it: no serious apparatus for language, civic education, or cultural integration, because why would you need to actively assimilate people into a way of life they, in some sense, already agreed with?
So migration happened at scale while assimilation happened at a fraction of that scale, if at all, and the gap between the two didn't close on its own. It calcified instead into parallel societies, competing loyalties, and a level of social trust that every serious measure shows eroding in exactly the countries that leaned hardest into the open-borders premise.
The crisis was never really about the migrants at all, though.
The emperor had no clothes, and too few people were willing to say so.
If anything, the self-inflicted collapse of Europe has been a stark lesson in what happens to societies once they stop being willing to ask new arrivals to integrate into anything in particular. A culture that won't defend its own norms, its own language, its own account of what it is and why it's worth preserving, isn't practicing tolerance so much as abdicating the one thing that gives newcomers something to actually integrate into in the first place.
It makes sense, then, that more cohesive, more purposeful populations saw an opportunity to claim power. And they did.
Confidence, it turns out, isn't optional set-dressing for a civilization; it's the load-bearing wall. Take it out, and openness stops being a strength and starts being a vacancy, one that gets filled. Not necessarily by force, though sometimes that too, but by whichever culture in the mix still believes, without irony or apology, that its own way of living is worth propagating.
None of this is fated.
The drift toward incoherence isn't physics, it's policy, and policy can be reversed by anyone willing to say plainly that a nation is allowed to have a culture, a set of expectations, and a right to ask people who arrive within it to actually join it rather than simply reside alongside it. But reversal requires the one thing currently in shortest supply among the people who could actually order it: the political will to say, out loud, that a civilization is permitted to believe in itself.
Nobody currently holding power seems interested in saying that.
Which leaves the rest of us with a strange kind of clarity: the diagnosis is not actually in dispute, only the courage to act on it.
