Trump appears to strut through the world forever studying his own image. He thinks out loud, and is incapable of reflection. He is unserious, unfocussed, and, at times, it seems, unhinged. Journalists are invited to the Oval Office to ask about infrastructure; he turns the subject to how Bill O’Reilly, late of Fox News, is a “good person,” blameless, like him, in matters of sexual harassment. A reporter asks about the missile attack on Syria; he feeds her a self-satisfied description of how he informed his Chinese guests at Mar-a-Lago of the strike over “the most beautiful piece of chocolate cake that you’ve ever seen.”
