If in managements estimation, they need to give up the North to get a good outcome, then I trust them to make that decision. Or if they believe we have a strong enough position to fight for what is rightfully ours, then I also trust them to make that decision.
The thing is, not you or I have all the information we need to make that call.
You are implying that if we don't give up the North, then we will lose everything, but you don't know jack (and neither do I).
