Cover art for Loyalty lyrics by American Head Charge

Well..judging from their other songs (like Coward, which begins with the Pledge)...i think this song refers to the gorvernment.

"Our original ideals, you let us down And betrayed our trust with all your promises"

It could be about a relationship, but i think these two sentences are a key to my interpretation.
