If you have Chia Head saying if we try to take him out he will nuke us, and our troops in Japan, why announce it? To give him time to set up aim for Japan?
We'll see what tomorrow brings.
As it stands now, nobody commits fully to resolve this crisis. A sudden turn of event could force players to act. Not at the time and the place they want, nor against a kind of problem they expected. That does not necessarily mean that it will lead to large scale destruction, but everybody could have their hands full for just catching up with the rapid turn of events.
Everybody is leery of uncertainty and trying their best to avoid it, but I suspect nobody can. On the other hand, doing nothing could also bring very dangerous situation. The problem has to be solved but there is no easy solution in any direction. People have been wasting a lot of time facing and accepting this reality.
