The continent’s problems are not caused by immigration or cultural politics but by economic and technological decline

Donald Trump’s new national security strategy offers a misguided assessment of Europe, long regarded as the US’s most reliable ally. Unrestrained immigration and other policies derided by administration officials as “woke”, it warns, could lead to “civilisational erasure” within a few decades.

That argument rests on a fundamental misreading of Europe’s current predicament. While the EU does face an existential threat, it has little to do with immigration or cultural politics. In fact, the share of foreign-born residents in the US is slightly higher than in Europe.
