If the South Gives energy via energy power lines to North Korea, we should use the latest technologies in energy waves to trace where the energy end points are and thus we can understand what it is used for. Also as frequency and wave technology gets better we can use these power lines to listen and capture data thru these energy sources and flows. Thus we will be able to tell if there are violations of agreements and monitor that nation until in the future other leaders take over power who may not be so keen on ruling with an iron fist or in Machiavellian Style. By using these methods we can know if in fact North Korea is doing underground in-mountain manufacturing of weapons, running high use centrifuges and exactly how big such facilities are. We can also bounce waves off the energy in the cables to see interior dimensions and energy wave emissions from above using radar assisted ground penetrating satellite technologies. Think on this.
