I need a change in history so in the year 2020, Ireland is ruled by a Constitutional Monarchy. It is still a catholic nation (not celtic), has a democratically elected parliament and leaders, and the monarchy is respected by the Irish citizens... at least most of them.
Every other nation, along with their political relationships, should be as close to the present as possible. This also applies to the Irish Republican Army. It still exists as an armed organization. However, I want this organization to only use political means (not bombing or gun violence) to achieve the aim to turning Ireland into a republic. There would be some connection (unofficial channel of sorts) between the monarchy and the IRA. And the portion that is in North Ireland will have the same fate as its real life counterpart: fight, lose, and then truce alongside demilitarisation.
