The only negotiation is how Russia is going to leave, its pathetic tbh, don't let fud over play the Russians hand, they are well and truly stuffed and have no way out. Nukes will not happen, the only reason that convoy isn't toast is to give them a chance to turn around.
Imo it's all over at this stage just needs the Russians to decide what they would prefer.
So you're saying that even though the Ukrainian soldiers could wipe out that convoy that has invaded their country they are deciding against it ?
I'm not sure I believe you.
