What term describes belligerent support of one's country?

The term that best describes belligerent support of one's country is jingoism. Jingoism refers to an extreme or aggressive form of nationalism characterized by the belief that one's country is superior to others and the readiness to act militarily in defense of national interests. This can lead to a confrontational stance towards other nations, often promoting the idea that military action is a valid means of supporting and demonstrating loyalty to one's country.

While patriotism is generally associated with love for one’s country, it does not necessarily imply hostility towards other nations. Nationalism, on the other hand, encompasses a broader spectrum of national pride and identity but can also exist in more benign forms. Globalism emphasizes interconnectedness and cooperation among nations, which contrasts with the aggressive, protective stance inherent in jingoism. Therefore, jingoism is the correct term when referring to a belligerent form of national support.
