Its the old problem of ideology again and how extreme we want to be. Frankly for relatively free countries I would just freeze the borders and go this is what you have. Might even extend that to all countries.
Why? well how far do you go, counties, towns? The world needs to move on, breaking away for purely nationalistic reasons is bullsh!t and should be given utter condemnation. More importantly it encourages outside interference.
One can understand if one particular grouping is getting a shafting, but preferably I would prefer to see that dealt with.
