When it comes to negotiating policy at best ambassadors are messengers. And in general our typical ambassador tends to end up being untrained with little to no foreign affairs experience, and none of them would have any political grounds to negotiate anything even of they were skilled.

And again we still run into the issue of trying to negotiate with both sides here when we are less than 12 hours away from a complete diplomatic breakdown between both sides, and peaceful reconciliation is all but impossible now given the mutually exclusive goals of both sides here.
