I am having trouble quantifying the risk North Korea poses to America. It would help if you could tell me how many other countries North Korea has attacked and/or invaded since it has been a country and how many countries the United States has attacked and/or invaded since it has been a country. Also, has any other corporation besides the U.S. been crazy enough to use thermonuclear explosives in an offensive way? And, is North Korea being provoked by the U.S. or any agents/contractors as was Japan in World War II?
Thank you for your attention.
