Hi @aggroed,
the smart one starts with Deescalation - great step.
In my world, the next step would be sitting together, having a few !BEER and start to "paint" a positive future where all grow steem together.
In my business life, I work a lot with top management in long workshops.
Having a drink together, often creates a better understanding for each other and imho this is needed in this situation.
Just my 20 cents...
