I’m half kidding, but since the Spanish American war, Americas entire reasoning for having boats in the water is to have our nation get attacked. We live two oceans away from danger.

Interestingly enough, Washington treaty basically straight up defined blue water navy as a tool of aggression and nobody was shocked about that because it's what everyone knew since like Persian Wars.
