Nice thread op but i feel ur making a lot of assumptions that art necessarily correct. for example, the 3 ft reference may indicate he's a a miracle kid with some magical super powers, like hari Krishna. after all u need some sort of power to kill a being like Satan. also the one doesn't have to be voted by america. and the middle between the two could refer to the middle east or south Asia, so he doesn't have to be Korean.
Personally my money is on the mahdi.
