There is something Fukuyama said in that podcast that I agree with, though: When asked if we were moving on to something new and possibly better that democracy, he said that it's quite possible that we won't move on to a new system of government at all. He pointed to a lot of the left talking about things that have been tried and have failed.
This makes me think of the jokey but sincere interest in communism. The tankie kind that throws around the hammer and sickle.
They say it'll be different if they do it again. The United States has committed the crime of letting millions go without adequate food and shelter. But when the USSR (and China and North Korea) was given the amount of power necessary to implement communism, they deliberatly killed millions of its citizens, which is worse.
No one is talking about what they'd do to ensure that does not happen. If that's not a concern that proponents of communism take seriously enough to explain concretely how they'd prevent genocide, then it is a flirtation with genocide.
