From my personal experience, Koreans typically have a deep dislike for anyone who is not Korean. Chinese, Japanese, American, African American, they are all disliked by Koreans. Korea and Japan are very nationalistic and racist countries.
I read somewhere that North Korean pilots rely on the "aura of Kim Il-sung" for protection from enemy missiles. Also, judging by pictures I've seen of North Korean troops, they don't carry more than one magazine for their AKs.
