Summary: A chilling account of what happens when the American presidency ceases to recognise meaningful limits on its own power.
In her 2022 Confidence Man: The Making of Donald Trump and the Breaking of America, Maggie Haberman provided both an explanation of what makes Donald Trump and a warning about what he might do if given power again.
Regime Change, written with Jonathan Swan, describes what happened when he was.

Drawing on hundreds of interviews and extraordinary access to the second Trump administration, Haberman and Swan document something more profound than the familiar chaos of Trump’s first presidency. This time Trump entered office understanding much better how the machinery of government worked, surrounded by people more willing to execute his wishes, and determined that the presidency should be constrained neither by the institutional conventions that frustrated him during his first term nor, frequently, by conventional understandings of the law itself.
The resulting picture is breathtaking: federal immigration agents and National Guard troops deployed into American cities; presidential power brought directly to bear upon businesses and institutions; and a war against Iran launched without specific congressional or UN authorization and accompanied by rhetoric and military conduct raising profound questions under both national and international law.
The virtue of Haberman and Swan’s reporting is that they rarely need to editorialise. The accumulation of detail makes the argument for them. What emerges is not simply an unusually aggressive presidency but a different understanding of the office: one in which personal will increasingly substitutes for institutional process and the traditional distinction between the interests of the president and those of the state becomes progressively harder to discern.
Perhaps the only reassuring thing that can be said about Trump is that he is mortal. After reading Regime Change, it is considerably less clear that the American republic as we have known it will outlive him
