jingoism /JING oh ism/ n.
Extreme patriotic chauvinism or nationalism marked especially by a belligerent foreign policy
Note: "To have a generous belief in the greatness of one's country is not chauvinism. It is the character of the latter quality to be wildly extravagant, to be fretful and childish and silly, to resent a doubt as an insult, and to offend by its very frankness." --Prof. H. Tuttle.
