who do you think is the most poweful person on earth?

hi bethel_101,what according to me that matters to answer your question is the way you look at it.although you have not asked about it..but i would like to explain it so that i can tell what i think about it.you can answer it in two ways:' 1.thinking logically and coherently..like the most powerful person on this earth is not the one who has got wealth or power or material to rule the world..but it is the one who has got brain and intelligence to win the world and self confidence to win himself/herself first..so any body who has these qualities can be called the most powerful.. 2.thinking practically or according to our common notion:..like the most powerful person is the one who has got money and power with him so that he is able to get all those things with which he can rule the world.. so you see world can be called ruled by two ways..by brain or by power and approach and the person who surely can rule the world satisfying both criteria is the one who has got brain as well as wealth..
