Who is the most powerful man ???

i think the president of unites states is the most powerful man on this earth.he is the one who decides the fate of all other countries and men on this planet

George W.Bush bcoz he is the person who decides which country is to be destroyed completely in the name of bringing peace for that country

i think that george w. bush is the most powerful man as he is the authority who can cause a war or can attack any country as of now. he can destroy any country without any reason, haahaaa he is the one who have destroyed afghanistan, iraq so u can't expect him to be not powerful. he is indeed the most powerful. as far as bill gates is concerned he is just a money monger and he is not as powerful as him. he cannot change the face of country but bush has dared to change the face of the world

inmy opinion,the person who is having more money in the world and a goo dname and fame is the ultimate powerful person.
