aggressive and warlike patriotism. Usually used in a derogatory sense. A politician might advocate a jingoistic foreign policy, but he would not call it that-a task which would be left to his opponents.
Jingoism is chauvinistic patriotism, usually associated with a hawkish political stance. In practice, it refers to sections of the general public who advocate bullying other countries or using whatever means necessary (usually military force) to safeguard a country's national interests.
