Very true. People forget some very basic info about North Korea.
1- North Korea is a
Heavily Industrialized country. It was centre of manufacturing excellence till before the dissolution of Soviet Union. North Korea and Soviets had deep connected relations. In short, North Korea has huge manufacturing infrastructure base.
2- It has
highly trained and skilled workforce due to the above. There are abundant of engineers, technicians and skilled professionals. I can confidently say that it has more skilled workforce than 95% of the countries in this World!
3-
North Korea has vast Iron ore and coal resources! In fact North exports these resources to China !! These are the two key ingredients to manufacture alloys and other items. And that is why North Korea can manufacture all this stuff.
4- North Korea's energy comes from Coal and its vast hydro resources !!
5- After the demise of Soviets, North Korea had issues with Oil Imports because Soviets use to give them plenty of oil. But interestingly, North Korea's oil consumption had actually declined further. The speculation is that
North Korea has now mastered BIOFUELS ! These are the fuels developed from its Agriculture products.
All in all, North Korea is a self-sufficient, self-sustaining Military Power, with vast natural resources, highly trained workforce and vast industrial manufacturing might !!!
Now let some idiot come and give some Twitter posts or some western garbage news as reference to undermine my post !!!
