North Korea Crisis

Ok boys and girls is it just me, or has North Korea gone CRAZY.  Why is there always such a level of hostility between the US and North Korea.  Clearly there was a conflict that caused the Korean war, however; at what point do we get over that experience.  Believe me; although I am a patriot, I understand that the United States does often times but their noses in other countries affairs; for which we (The United States) should not be involved in, but treating nuclear warfare, over anything that does not involve land, finance, or family of your own just seems foolish and demonic.  Of course, North Korea says they simply want to test their nuclear abilities through a test launch, however; the United Nations and the United States seem very nervous about North Korea wanting to conduct test launches.  Why don't we just simply put President Barack Obama and the President of North Korea in a boxing ring and just let them slug it out, and leave us; (the citizens want to live) out of it.  Personally, I’ll take $100.00 on the President of North Korea, because of the kick boxing thing they do.  Please share your thoughts.
