What does it say about us?

What does it say about us Americans that our national anthem is all about victory in battle? It exhorts our "banner" (an emblem of battle), and brags about our "rockets red glare" and "bombs bursting in air". Contrast this with a hypothetical national song which would celebrate our being people who relish freedom, equality and peace. Which would creat the most constructive attitudes in the minds of our youth? Which would place our values in the best order of priority? Which would create the best image in the eyes of other countries?
