We’re a country that’s $40 trillion in debt and counting; dealing soberly with long-term threats isn’t really our thing.

There’s no such thing as luxury nationalism, but the idea may have been inevitable in a population that imagines inexhaustible wealth and power as its birthright. And given Donald Trump’s upbringing and approach to the world, that he’d end up as the face of it may have been inevitable too.
