Bullcrap.
It is in fact pretty close to an example from antiquity:
the Delian League.
Ask the Chileans, the Iranians, the Guatemalans, the Salvadorians etc. about the giving nature of the US. The US has only the interests of its corporations in mind. Not that there is anything new or different about an empire that only has its own interests at heart. What's new is the number of people willing to believe that it is all done for noble purposes.
