Since you are reading why nations fail I would like to recommend a pairing. How democracies die by Daniel Ziblatt and Steven Levitsky. The central thesis here is parties are the gatekeepers of democracies and when they put party before nation they erode the democracy that eventually fails. More often it’s a slow degrade than a sudden spectacular collapse. The erosion paves way for leaders that are more “spectacular” in every negative way than the last one. Makes you think if trump is the problem or merely a symptom. GOP put party win before a nation by agreeing to nominate an unfit individual for office. They failed as gatekeepers. His presidency will lead to future leaders justifying behaving like him or worse and the “norm” Keeps degrading over time to the point where people are fed up and bring into power a person that they don’t fully understand and one who plays to their fears and portrays themself as their only solution. The book is amazing to read specially with the context of last 4 - 6 years of American politics.
