First of all, North Korea is just a poor excuse of a communist country. It's just another name for "discrete Chinese business" that China would not be able to openly pursue on their own for everybody would find them suspicious of starting WWIII in no time. Oh right, one might think they're on the verge of declaring it if both sides don't stop threatening the other concerning the implementation of more aggressive economic measures against the other nation...
The devil loves to begin wars, fallen humans also love to be part of them. Some of their own victims even end up loving the way they feel while living in such troubled times for they think their nation needs them or they just think they can't live without a tyrant telling them what to do next. Yeah, sin can make us feel like real donkeys disguised as human beings. Have you noticed that most wars begin for uncertain reasons? It's quite rare to know the actual motives or situations that lead us to partake in such a terrible mistake, WWII is one of those unusual cases and even then the reason behind is even more stupid than we might have thought at first.
Passions = wars
Even if we're passionate believers, the enemy will try to lead us to confusion and disbelief. So no matter what we think, we always end up involved in warfare. Hopefully we all can say it's just spiritual and no blood need to be shed.
Don't forget to pray!
