North Korea either gives up it's nuclear weapons or at some point it will only be dust there

The is the reality we are looking at today. Trump is not the kind of person to put up with North Korea for 4 or 8 years acting like this every day. So,  likely during the next 4 to 8 years we will either see North Korea giving up it's nuclear weapons or we will see nukes going off form north korea one day and a massive retaliation from at least the U.S. but likely also from China. China is pissed with North Korea too.

North Korea is like a juvenile delinquent living next door to China that threatens to shoot everyone on the block with a gun in his bedroom. Some day, that weapon will either be taken away form him or he will be shot. This is a given at this point. However, as we all know there might be other scenarios none of us would believe at present.
