Why did America become the victor of the 20th century, and why does it collapse so quickly?
The twentieth century is often described as an era of ideological warfare. Totalitarianism, communism, and liberal democracy competed with one another, and liberal democracy ultimately prevailed. The representative of liberal democracy was the United States, and the American political system was even described as the “end of history.” This phrase meant that liberal democracy was considered the best possible political system, and that political evolution had essentially reached its final form.
