What would NI Unionists do if Scotland left the union?

Short term it'd probably cause more anger and bad behaviour but it would be the death of much of their ideology in the long term.

When you get stuff like that politician ranting about the queen being Anglican and not Presbyterian, you see that for many their loyalty is to Scottish Presbyterianism, not to the crown.

They didn't seem too impressed with the Presbyterian pastor from the Isles who said something to the effect that Gaelic was the language of God, so are selective even in that.

I doubt if Unionists with a capital U would change very much if Scotland left the UK.

You must surely know by now that unionists that live in Northern Ireland are first & foremost, Irishmen and Irishwomen. They're not Scottish, they've been here for centuries and have every bit as much right to live on this island as you or I. And will remain here.

The best hope for the future is to build close relationships between all the people of this island and seek to construct a new state that will respect all.

It would create a major crisis of identity within unionism because Scotland is the region of the UK that they are closest to, not just geographically but also culturally. Scotland would also likely have the eventual goal of EU membership, raising the uncomfortable scenario for unionists of the ROI and Scotland ultimately together in one union, while NI would be left an awkward satellite of England and Wales outside of it. We have had it established that if NI votes for reunification, it will immediately enter the EU without any waiting period required. That becomes an even more enticing prospect if the above scenario takes place.

How would unionist politicians react to Scotland leaving? I suspect by trying to forge closer ties with England and Wales, and talking up the importance of this relationship. You would hear a lot of commentary about how it is now incumbent upon NI unionism to step up and fill the void left by Scotland. There would for sure be elements of the Tory party that would encourage this talk too. Would it carry much weight with the ordinary people of England and Wales? I doubt it. I suspect Scotland departing would be much more likely to trigger a public conversation within England and Wales as to what sort of future these nations would now need. Would people want to continue waving union jack flags if Scotland has walked away? I suspect the English and Welsh flags would become much more prominent. And that's a nightmare scenario for NI unionists because if England and Wales were to become more introspective, that is a debate that NI unionists cannot be part of. That would lead to increasing numbers of unaligned voters in NI - neither unionist nor nationalist - having to ask themselves whether it would make sense logically to be a core part of one nation, and also the EU, or to be a third wheel of a UK rapidly travelling in different directions.

Add into this uncertain future the prospect of Charles ascending the throne at some stage, and the possible consequence of many Commonwealth countries (including Scotland perhaps?) deciding to respectfully decline being represented by him, which could lead to the status of the monarchy waning within these islands and abroad, which would add even more uncertainty to the traditional unionist outlook in NI.

This decade that we're in has the potential of being massively destablising for NI unionists, and I'm not sure the majority of unionists appreciate this. They are focusing on the protocol, and ignoring the much more serious shifts taking place. What history tells us is if it does all indeed unravel, it could unravel very quickly.
