Epic Level Paladin
Str 30 (world's only true superpower. Even if you think their power's on the decline or think it's hollow, power is oft defined by perception and none can deny America is SEEN as the strongest nation on earth)
Dex 12 (America changes fairly rapidly, considering all that's happened in their relatively short history, but they're also rather stable and conservative which keeps them from moving all that fast)
Con 25 (Sure you can hurt them, but America is far too stable to kill. What people think of as instability that's going to bring everything down is a very relative concept, and an unstable America would still be more stable than many operating nations)
Int 18 (First-world education system, and although there is definite societal gap between the educated and more ignorant masses, America's research and development is still some of the largest and best-funded in the world)
Wis 8 (Strong internal divisions, indecisive society. Reflects disparity between available knowledge and the American public's ability to apply it.)
Cha 16 (Not their likability per se, force of personality. They can persuade well, either through diplomacy or intimidation, and despite relatively recent and short-term difficulties, America has a lot of long-term goodwill built up.)
Explination: Classic "Moralfag" Paladin. Can be scizophrenic in its' values or opinions, and rubs a lot of people the wrong way. So long as God keeps blessing it, though (or as long as America thinks God is blessing it), it is strong in its' convictions that it has not fallen.
This reflects America more as its' outer appearance, if you feel this is rather a sham then you'd likely suspect more along the lines of a Lawful Evil manipulator or a Chaotic Neutral scitzo.
