Why is nationalism dangerous? Justify your answer. Give examples from history.

Nationalism is dangerous because it is an infringement of the rights of other races, because it can lead either to war or to popular unrest and revolutions. From the course of history, we can cite the Second World War, in which the Nazis boasted of nationalists, who believed that they were superior to all other races, that other races should be their slaves, which led to the mass extermination of Jews and the gathering of the population of many countries in the conslage.
