America was one of the pioneers of offering free speech, freedom of religion, freedom from Kings and Queens in this world (like the Qur'an does). It was the first country to reject slavery (having practiced it); The country with amazing firsts to offer as inventions to benefit mankind and the first pre dominantly white country to elect a black president!! It was also the country to introduce atomic weapons and first to use them (not a good idea)!!
I'ts has on it's coin "In God We Trust" so it is not discounting God from providing values for human rights and the right of an individual to achieve his/her highest potential.
It will suffer from the mistakes it makes (whether in foregin policy or financial blunders) but it has the capablity to live and learn and correct it's course. If it were not hostage to certain lobbies manipulating it for subjective reasons, it would have kept it's leadership in the world.
However, it is not going anywhere any time soon. It makes mistakes, admits it has and takes corrective measures to correct it's course. That is a healthy attitude. There are some areas where it is slow to learn (foreign policy) but learn it will because the alternative would be isolation.
