Well isn't it obvious? Let me illustrate by a mock conversation. Note, this is after he has befriended every world leader and the like.
Obama: "Hi there Mr. Berlusconi, that's a fine country you have there!"
Mr. Berlusconi: "Why thank you, my finely tanned friend!"
Obama: "Now, I hate to be a nuisance or anything, but would you mind giving me your country?"
Mr. Berlusconi: "Beg your pardon, my well tanned friend, but are you out of your mind?"
Obama: (to other country leaders) "THIS MAN IS A RACIST! ARREST HIM FOR HUMAN RIGHTS VIOLATION!"
*Obama takes over Italy*
Just kidding, Obama seems to be a fine fellow indeed. Let him make friends with everybody out there, he has a lot to make up for after the Bush administration.
