The worst thing about the style of this new/old administration—well, after the perversity, the stupidity, the moral ugliness are all taken into account, perhaps—is just how juvenile they all seem. I won't say "young," because many of them are very much not young. But unmistakably juvenile—even the old ones. They are living embodiments of the "puerilism" that Johan Huizinga associated with the far-right politics of the 1930s—and which he saw as the opposite of all true youthfulness, playfulness, and humor.
The "puerilism" of the administration is most obviously on display in the actions of Musk's team of twenty-something "DOGE" hacks who are currently running around the federal government firing all the adults. But one can see it too every time J.D. Vance opens his mouth.
