Don't know. Avoiding war here would be the humane thing to do, but accidents do happen. Kinda like seeing a capitalist country telling a communist dictatorship to go pound sand. Very refreshing. The future here is in the hand of the Koreans, as it should be. They have hundreds of thousands of lives on the line.
Do not rule out the stupidity factor. The NorKs have fine-tuned their brinksmanship policies over the years.
However, at sometime in the life of any politician or government, the ability to succeed despite itself runs out.
That's when the Spam hits the proverbial fan and the results will not be evenly distributed.
This could spiral out of control very quickly.
