Ok, we are in danger of falling into ambiguous genius of the GFA, it being all things to all people, so its possible we all have different interpretations.
That was removed and replaced with an entitlement for anyone born on the island to claim Irish citizenship. Allowing someone to claim citizenship and claiming a territory as your own are two very different things.
Except it wasn't. There is no entitlement for anyone born on the island of Ireland to claim Irish citizenship in Article 2. There is a right for those born on the island of Ireland, which includes its islands and seas, to be part of the "Irish Nation" which, Art 1 sets out to be inalienable, indefeasible and sovereign right to develop life, political and economic etc....
They also removed the 'pending the re-integration of the national territory' piece and replaced that with a 'firm will' to unite all under a united Ireland, specifically calling out that they are two separate jurisdictions.
Yes, 'pending re-integration' implies that every Irish government is duty bound to pursue and prepare for that objective. I can see how from a Unionist perspective that would be considered aggressive or intimidating. The other controversial element of that Article was "and without prejudice to
the right of the parliament and government established by this constitution to exercise jurisdiction over the whole territory" . Again from a Unionist perspective it is understandable the sense of hostility to this.
So those articles have been diluted with more aspirational language, yet the territorial claim remains, Art 3 "It is the firm will of the Irish nation, in harmony and friendship, to unite all the people who share
the territory of the island of Ireland" .
But admittedly, we can go around the houses on this one until the cows come home....its just a matter of interpretation. Do you think NI is a 'foreign country'? I don't.
I suspect the Greens dont either. Come to think of it, I doubt FF do, im not sure if FG do, certainly not SF, nor the SDLP for that matter. PBP are also an all-ireland political organisation.
So my guess is that, somewhere in the region of 80% of all political persuasions, north and south, do not consider NI - or conversely, The Republic, as foreign.
