A chilling and clear-eyed warning about the threats to our democracy posed by the increasing radicalization of the Republican Party, from a leading historian and intellectual The 2024 election could be the last free election held in a unified America. So warns Robert Kagan in this brilliant and terrifying analysis of the perilous state of democracy in the United States today. If Donald Trump loses the upcoming election, as he did in 2020, but refuses to accept the result, as he also did in the last election, he is likely to call on his millions of followers to repudiate the election results. It will be a short step from there to Republican-dominated states rejecting the legitimacy of the federal government and effectively seceding. The United States at that point will cease to be united, with grave consequences for both Americans and the world. In Rebellion, Kagan dives deeper than the op-eds and think pieces to explore the historical forces that have brought us to this moment—in particular the long history of opposition to liberalism, and to government, that has shaped America’s character from the time of the Revolution to today. Trump’s unique capacity to tap into that tradition of dissent and circumvent the American system has brought us to the edge of dissolution—not for the first time in our history but possibly the last. This is an elegant and deeply informed synthesis of history, contemporary politics, and ideas that sheds light on this crucial moment.
