So despite protests South Korea did its announced live fire artillery drill at the disputed border today but North Korea did not immediately respond in kind.
Good. With the South Korean military on high alarm and a lot of the U.S. fleet around an immediate response would have been quite dangerous. And why fight on your enemies' terms?
But just as the South could not back off for fear of losing face, the North will now have to do something to keep its face. It will do that something pretty soon but probably still at a surprising place and time.
What might something be?
Another nuke test or firing off of some bigger missiles is a possibility but might be just too normal and predictable to be seen as an appropriate response. Something asymmetric like a daring infiltration into the South to blow up this or that bridge or military outpost is my best guess.
But your guess is as good as mine. How do you think North Korea will respond to this provocation?
