As a ROTC and student of majoring international study, I have plenties of opportunites to hear and analyze the problem of North Korea. Though the NK is our same race, we regard them as our only enemy in this era, and pay careful attention to them.
We predict that they already finished the nuke missile testing and they have fifty-tons kilograms of explosive materials now. (such as plutonium or HEU) The HEU(Highly Enriched Uranium) is no more available for them to use, because the U.S. accepting their report of the quantaty of HEU, and promised to support them economically such as electricity and heavy oils.
The exit from the pooverty is making harmony with the world and abandon their WMD.
