As you all know, former President Jimmy Carter was key in deescalating the nuclear situation between the U.S. and North Korea. As I was surfing the internet, I came across this article entitled "U.S.-North Korea war seems 'strong possibility". The author of this article is Jimmy Carter, it was published in 2003. Carter says that another war with North Korea is possible and that North Korea has "a cultural and almost sacred commitment for its leaders not to back down, even in the face of international condemnation and the most severe political and economic pressure". This sounds very typicall of North Korean diplomacy.
The article does not have much new information but the interesting thing is that it is a first hand account and primary resource about the incidents with North Korea.
