Many people ask me this and I am happy to explain the situation. Korea was once an whole country but civil war divided it into two countries- North and South. Geography denied an East West division.
Communism attracted the North and Capitalism the South. It is like oil and water, the two cannot mix. That's about it.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
