“What’s globalism, by the way?” asks Jay. I can imagine a definition for the word that would make it useful. It could denote the view that borders and sovereignty are outdated, or that we should have a global government over national ones, or that we should regard ourselves as having no greater obligations to fellow citizens than to foreigners. When I come across the word, though, its chief function seems to be to blur the distinction between such fringe views and the view that putting 35 percent tariffs on imports is a bad idea.
