Answer:
An extreme feeling of patriotism that is based on fear or aggression and influences prejudice against other nations is called jingoism.
Step-by-step explanation:
Jingoism is a form of exaggerated patriotism. It is often used when it is about an aggressive foreign policy of a country, while the country in question says it does not want to fight, but is provoked to do so or that it has noble goals in mind, which must be achieved through aggression.
In American history, jingoism during the late 1800s and early 1900s placed the safeguarding of the nation's interests and the country's national identity as vital priorities: a very aggressive foreign policy was then adopted, connected on the other hand to a tendency to isolationism.
