Are you suggesting that Russia or the US are supplying North Korea with the know-how? :P

1. He/she was only quoting the Korea Herald.

2. We don't have credentials on these "South Korean experts." I would expect that if they are not part of the military then they might have even less knowledge of what they are talking about.

3. North Korea is a bigger threat to South Korea than China is. That may skew opinions.
