To "address the problem" is similar to the term "address the ball" in golf or baseball. In the large sense "address" is used to mean to "confront," or to "place yourself in position" - in this case to "solve the problem." It is not the same meaning as to "solve the problem" because sometimes problems are not easy to solve and/or take time. Therefore, one must "engage yourself in the problem," think about it, make efforts to resolve it, etc.
The idea is that a King rules a country while an Emperor rules an empire, and empires are made up of more than one country. In practice, these definitions can be applied in various ways. Some countries are larger than some empires, since there is no specific defined size for a country to be. One really large country could be larger than ten small countries. So in some situations, a king might be a greater ruler than an emperor. But the idea is, emperors claim to be greater.
