Which phrase encapsulates the essence of jingoism?

The phrase "America first" captures the essence of jingoism effectively because it stresses a nationalistic sentiment that prioritizes American interests and superiority over those of other nations. Jingoism is characterized by an aggressive foreign policy and an unwavering belief in one's nation as being greater than others.

This phrase aligns with historical contexts where jingoism often fueled military engagements and expansionist policies, emphasizing the idea that America should focus on its own needs and assert its power on the global stage. It evokes a sense of pride and often leads to a dismissive attitude towards international cooperation or partnership, central themes in jingoistic rhetoric.

In contrast, "peaceful coexistence," "support our troops," and "global unity" reflect more cooperative or supportive sentiments that do not encompass the aggressive, nationalistic fervor that defines jingoism. Each of those phrases leans towards diplomacy, unity, or collective support rather than the isolationist, superiority-focused stance inherent in jingoism.
