If an alien lands his spaceship in front of you and asks, "Take me to your leader!", to whom will you take him?

You know who your President is, or your Mayor or Governor or your Mom but sometimes you don’t necessarily think any of them represents your own unique idea of what the leader of the human race should be like.

So please feel free to bring the alien to anyone you think best represents a real leader of mankind. And you can even ask the alien to bring you back in time, in another place maybe, to introduce him to your ideal leader who then existed.
