The smaller English-speaking countries, above all New Zealand (where I live), with the population of just one very average American state, stand to benefit massively from this exodus, provided we aren't stupid enough to emulate Trump-era policies ourselves.

As you suggest, there is a precedent. In our case, a sizable influx of central-European refugees from Nazism, of whom the philosopher Karl Popper is the best known, livelied up New Zealand in the 1930s and 1940s.

That influx fostered the rise of a café society in our cities, along with the establishment of new industries whose secrets arrived with the Europeans.

It is bizarre to think that something like this could happen again.

So, Trump is a cloud with a silver lining from our point of view. Though, of course, it is America's loss.
