Thank you Cathy!
At this stage I think we would also see a return to significant Loyalist violence (as they would know that it was the end game for them), also with probably no real reciprocation from the IRA as they will play the long game and know that it would not help their cause ultimately.
Bearstrikesback from the previous thread.
I think the Loyalist violence would involve a significant amount of infighting but also provocative terrorist attacks on 'non-combatant' NI citizens like schools or congregations, weddings, significant funerals, etc ('non-combatant' as opposed to attacks on paramilitaries on the other side) with the aim being to provoke the Provos into retaliation, or to provoke breakaway Republican paramilitaries into action, which might happen if the Provos don't bite.
I can see support for a united Ireland growing in Ireland if such a tack was taken. I can also see international support developing, and support in the form of buying Irish government bonds if a referendum in NI were to lead to some sort of all-island state emerging (whether federal or unitary).
Federal being the equivalent of 'a TV in every room'.
