Some examples are when you wave the flag and sing the National Anthem.
This could cause a war because some people may think that it is wrong to think that your country is better than everyone else's. Some countries might want to challenge a country that is nationalistic to see who is the better country. In world war 1 each country tried to prove their dominance and power thus leading to a direct cause to the war.
