America is none of the above, America is an Empire
an empire makes temporary agreements,
its just like East India Company with the 21st Century flavour.
An Empire cant be static, it has to expand to sustain itself hence Americans "NEED" to have an evil figure or regime to aim and direct their opposition and sell it to the public for the Empires continued growth.
Pakistan is but just a secondary objective in the bigger schemes of this and so is India.
Look at the American military bases across the globe, in the absence of a potential power that can confront it on equal grounds American Empire will continue to be more blatant, aggressive and outrageous in its goals.
The only option for countries like Pakistan is to hope it doesnt call in the Americans empires scheme of things (sadly not possible). Or try to align itself with any other power that has the capacity to confront the aggressive empire (none exists at the moment). Or try to shape the national policy and use diplomacy to stay out of direct confrontation with the empire and get some momentary relief.
As long as the world remains unipolar , countries from Cuba to Vietnam and Korea will continue to suffer at the hands of American hegemony and aggression.
American president Roosevelt dismissed the American eagle as a symbol, according to him, the Grizzly bear represented the mood & nature of USA far better. Just like a Grizzly which lives alone, has no friends, & has no concept of friends and the whole woodland is its property where it can reign terror on its natural inhabitants and any strangers alike.
Looking at the two political parties of America, you cant really see any much difference in foreign policy and tackling in Americas so called war on terror (read war of terror). Whatever the republicans did in the previous governments has been matched and doubled by the current administration and IF republicans ever get to power they will respond with scaling up the aggression further.
