You said: "it's about the fact we are hated in the ME even by those we have freed (IOW by the people we are tring to save) . That many here at home don't care any more (IOW the people we are trying to protect)".
Now that is how I heard the song as well...so HOW is that not to some degree at least a song which gives voice to sentiments against this current war?
I'd kiss the ground of the USA too if I just came back from war. I suspect many of our returning Troops do to.
