/kloc-in the 0/9th century, due to the unbalanced development of capitalism in Europe, some European countries did not enter the capitalist stage, thus becoming servant countries and enslaved countries of capitalist countries. Therefore, nationalism in the19th century means national liberation and democracy, that is, resisting tyranny and striving for national independence. As mankind entered the second half of the twentieth century, most countries gained independence, and the negative effects of nationalism such as narrowness and inferiority gradually emerged. In fact, nationalism has begun to exclude democracy. (Take Germany in World War II as an example) Therefore, I think there is no future and it is not conducive to the development of independent countries.
