Nk has the biggest or one of the biggest armies in the world but the us has the most powerful not to mention powerful allies if Russia and China were to side with nk the us would have a harder time winning but they would probably win if north korea lost most of its military they would be over because they wouldn't be able to recruit more soldiers because many people in nk are starving to death a 20 year old has the body of a 12 year old over there because they don't have enough food to grow that much while the us has a whole country of people to be drafted into the military sorry for all the grammer mistakes I wrote a whole paragraph before to answer you then accidently hit cancel.
Short. Once north korea looses power they are done. 1 nuke done.
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.
