https://www.merriam-webster.com/dictionary/jingoism

extreme chauvinism or nationalism marked especially by a belligerent foreign policy

Jingoism is nationalism in the form of aggressive and proactive foreign policy, such as a country's advocacy for the use of threats or actual force, as opposed to peaceful relations, in efforts to safeguard what it perceives as its national interests. Colloquially, jingoism is excessive bias in judging one's own country as superior to others – an extreme type of nationalism.
