I had the incredibly good fortune to take a course from Dr. Joseph S. Nye, Jr.
One of the concepts he hammered into us was the importance of "soft power":

Notable examples include:
* the Athenian city-state's dominance in Ancient Greece
* the Pax Romana
* the collapse of the British Empire
Soft power deals with such matters as: would an 18 year old in {fill in the blank with country} rather own a pair of American-style blue jeans, or an outfit associated with his/her own culture? Would that same 18 year old prefer to be seen in public with a Coke, or with a beverage associated with his/her own culture?
It also deals with perceptions of benevolence: does that 18 year old believe that America is benevolent and just in its dealings with his/her culture?
One important barometer that would be interesting to measure: how many non-aligned nations are investing state resources in educating their elite/promising students in English, versus Mandarin?
