Re: it wouldn't surprise me if...
That would be tantamount to Westminster abandoning NI. This is dangerous talk. If it happened then expect The Troubles to resurface. It is on the same level as saying that [the Republic of] Ireland should also invoke Article 50. That would solve the EU GB dilemma immediately and without question, but it would cause tremendous turmoil in Ireland. Let's not visit either of these scenarios unless it comes as the result of an agreed democratic process instigated from within the whole of Ireland itself. That process, without aiming at any defined result, may take years, but it can not be rushed.
