No one knows what will happen because it could still go either way. The reason why they haven't even issued a warning on the travel boards is because nobody knows and a warning could destroy the Korean economy and send the stocks into a nose dive. The next move keeps being placed on North Korea's shoulders because South Korea does not want to take a turn. So it is catch 22! You can leave and have nothing happen and will have given up the E1 or you can stay and possibly get stuck in a war zone.

Call me a coward, but I am leaving. The next big explosion and you know everyone will be running for the airports.

Good luck to you in whatever you decide.
