This America First president is himself an American first. Indeed, a further reason for the disdain of historians is because, historically speaking, his administration has been like no other. The chaos of staff turnover – two secretaries of state, two secretaries of defence, two attorneys general, three White House chiefs of staff, and a revolving door of senior West Wing aides. The foreign policy by tweet. The chumminess with adversarial authoritarian leaders, such as Kim Jong-un and Vladimir Putin. The blurring of ethical lines supposedly separating the Trump White House from the Trump business empire. The Russia collusion investigation, which has raised questions, so far unsettled, about his true allegiance.
