There is no such thing as a "Palestinian" or a "Jordanian".
You are correct, of course. It is a vast and inacurate oversimplification. Care to take a shot at explaining why the King of Jordan, whose family is not from Jordan, married a woman who's family is kind of from Jordan, but not the right kind, for political reasons? Though as several people on this thread have pointed out if you had to marry someone for political reasons she's not a bad looking choice.
