The KNU and the Tatmadow can form a committee and they can argue over the next few years their competing lists of war atrocities.
If you want to stop the war, stop killing each other.
I have my own pet gripe: NUG pats itself on the back every time it murders someone who's trying to implement preparing for voting, or conducting census work to verify who can vote.
The last election didn't elect people for life. At some point in time you either conduct new elections, or declare NUG to be a dictatorship.
