They are always problem. If we don't unite,we will always fight with them. I'm talking about North Korea,. Recently, North Korea launched the nuclear missiles and made a nuclear-powred submarine. their president, 김정은's goal is simple, to make the U.S.A.obey him. Of course he can't make that much money. he sells weapons to IS and makes the public suffer. When we, South Korea, sendfood aids, he takes some of them, and give it to his scientists to make nuclear weapons. In North Korea, when the North Koreans don't obey 김정은's order, they die with guns. If hthe public don't obey 김정은, his party will get to kill all of them. I always have a doubt, then, why don't we get to kill hisfamily and him? Kim's family has it's power, so party's executives will fight and get the seat and bit will be a paradox. Korea needs to get power. So many powerful countries are near us, geographically and historically. We can develope much more if we use North Korea's resources and our science skills.
