“An American ‘Caesarism’ has now become flesh.” I wrote this in March 2016, even before Donald Trump had become the Republican nominee for the presidency. Today, the transformation of the democratic republic into an autocracy has advanced. By 2024, it might be irreversible. If this does indeed happen, it will change almost everything in the world.

Nobody has outlined the danger more compellingly than Robert Kagan. His argument can be reduced to two main elements. First, the Republican party is defined not by ideology, but by its loyalty to Trump. Second, the amateurish “stop the steal” movement of the last election has now morphed into a well-advanced project. One part of this project is to remove officials who stopped Trump’s effort to reverse the results in 2020. But its main aim is to shift responsibility for deciding electoral outcomes to Republican-controlled legislatures.

Thus, health permitting, Trump will be the next Republican candidate. He will be backed by a party that is now his tool. Most important, in the words of David Frum, erstwhile speechwriter for George W Bush, “what the United States did not have before 2020 was a large national movement willing to justify mob violence to claim political power. Now it does.” It does so because its members believe their opponents are not “real” Americans. A liberal democracy cannot long endure if a major party believes defeat is illegitimate and must be rendered impossible.
