The end of history means that the American system is the best in the world. This is everyone's future goal. Although the American system is really outstanding in the world at present, no one can guarantee that there will be no better system in the future. And it has failed in many backward countries.

The American system is only 250 years old, and the stereotype is only 50 years. From a historical point of view, such a little time cannot be used to prove the optimization of a system. Even the ancient feudal rule in China was "optimal" for 2000 years, but it was overthrown. It is a bit arrogant to say that the system of only 250 years is the best.

The clash of civilizations refers to the division of human beings by various civilizations, and the ensuing conflicts are generally the clash of civilizations. But conflicts always come from interests rather than spirit. This statement can't explain why the United States participates in various conflicts-anyone who is a little smarter knows that this is not because there is an American Protestant in every conflict, but because the United States has the biggest fist and the most money.
