The political focus on nationalism has evolved over the last five centuries. After World War II, some predicted an end to nationalism, but they were wrong. Today nationalism is stronger, and the independence of Afro-Asian countries, the former Soviet republics, and other states has made it even more inclusive. Nationalism has both positive and negative aspects. On the negative side, nationalism has led to isolationism, feelings of superiority, suspicion of others, and messianism.
Nationalism can also cause instability when there is a lack of fit between states and nations.
Domestic instability and foreign intervention are often the result of such national instability. Nationalism has also led to a multiplicity of microstates. There are many enthnonational groups that are seeking or may seek independence. Among other considerations, this could lead to the further multiplicity of microstates. In a world of transnational global forces and problems, many condemn nationalism as outmoded and perilous.
