Oddly enough as much as some actors would like to see it change, the U.S.A.’s world influence is probably at or near it’s peak, the USSR is just a shell of it’s self, china as much as it would like to be is no match for the U.S. in economic or other area’s.
This is probably the first time in history where one nation held as much sway over the rest of the world as the U.S.A. does now.
