In the recent series news, as everyone knows, the North Korea focuses on the United States, not the South Korea. The United States cannot bring the peace for the South Korea, but let the North Korea want to attack the South Korea more. Of course, the North Korea cannot use the nuclear weapons to threaten the South Korea, but actually it can be adopted as a defensive weapon. The North Korea has a strong army with a weak navy, so that it's very hard to attack the United States via Alaska. If the North Korea has enough submarines and troop carriers, the United States will feel very difficult to deal with it without adopting the nuclear weapons. Please respect to every country.
