You found a heart!
Well, if anything, you said that "they must have a plan we can't see yet". I said that the plan is quite visible already: looking all scary and threatening to get some negotiations going with the US and China in exchange for food and economic help. It's the only hand they can play and they are playing it, otherwise the country would fall into internal chaos.
It's not that they have a mysterious plan all this weapon shuffling is a part of, their entire plan is just shaking their fists.
