"As for the ending; isn't it accepted that America was founded under God to spread freedom and liberty, both religious and economic?"
No, I doubt it is "accepted" by very many, beyond the religious faction, of Bush's party.
Many Republicans and conservatives are not among those, who insist everything political and American must be heavily infused with Christian religious references.
actually if you leave God out of it {even though our founders didn't}, encouraging freedom and supportiing it and warning tyrants we are watching, is not a bad thing. It is pretty idealistic but also pragmatic. I think GWB truly believe God is involved and exacts certain things from us for our incredibly free country. But even if not inspired by God, what vision he is embracing and leading this country toward is without doubt the most idealistic decent thing I have seen here in years. At least you have to admit he isn't encouraging rampant hedonism, narcissism and isolationism. I can support his vision of our place in the world, think it is worthwhile and good whether I accept his idea about its origins or not. You don't have to be a Christian to think the 10 Commandments are a pretty good idea.
