Britain: Will Scotland declare independence unilaterally?

Britain: Will Scotland declare independence unilaterally?

The Brexit earthquake just happened but there are tremors in Scotland with QC stating that Scottish Parliament could call a Referendum without the authorization of the Westminster Parliament. 

Whether it is legal or illegal for Scotland to declare independence is irrelevant. What is relevant is the question of what could happen if Scotland were to unilaterally declare independence. In the years after the 2016 Referendum on EU Membership, the movement towards Scottish independence has been reinforced by a General Election in which SNP has reaffirmed its position as the party of Scotland going against what happened in other parts of the United Kingdom where the Conservative Party won in Labour Party heartlands.

The present crisis in the British Monarchy doesn't help. For many years, the Monarchy has been the glue that kept together the United Kingdom. A weaker Monarchy is a recipe for trouble. In geopolitical terms, Scotland is moving towards EU while the rest of Britain is in limbo. For the moment, at least some kind of balance has been in Northern Ireland with the restoration of the Northern Ireland Assembly.

Trying to keep the United Kingdom in its present form by force could lead to civil war. But if the use of force is out of the question, how would people on both sides of the border react if the Scottish Parliament decides to call a Referendum or decides to declare independence unilaterally. In the 1920s, there was the partition of Ireland giving birth to the Republic of Ireland in the south of Ireland and the Province of Northern Ireland in the north of Ireland. A century later, could this be the time for Scotland?
