Dear
@Purple you are getting into a bit of a spin.
Let's take a step back.
Art 2&3 of the Constitution, for so long the bug bear of unionists had this to say in 1937.
"
The national territory consists of the whole island of Ireland, its islands and the territorial seas"
and
"
without prejudice to the right of the parliament and government established by this constitution to exercise jurisdiction over the whole territory...."
It is clear that the 1937 Constitution considered the whole country as Ireland and the State to be Ireland, save for the acceptance that any laws enacted by the Parliament established under the 1937 Constitution would only be applicable to area of the Irish Free State despite having the authority to apply to the whole country.
Fast forward to 1998 and the explicit claim of physical territory over all Ireland and the right to enact laws has been ceded to institutions established on a shared basis by their respective authorities, Government of Ireland and Government of GB & NI.
In 1937 Ireland had a territorial claim that was in reality an empty jesture and purely aspirational.
In 1998 (and 1985 AIA before it) the Irish State has a real definitive say in the affairs, in part, of the affairs of NI through an international agreement between Ireland and UK.
In case you hadn't noticed, between the UK and EU this real definitive say in the affairs of NI, on a shared basis, has caused a bit of a scuffle over sovereignty, trade etc.
If the Irish State were merely the 26 Republic of Ireland that you claim it to be, then Dublin would have no business sticking its nose in. The EU would have no business standing by Irelands wishes for a sea border.
But the EU has stood steadfast behind Ireland, so far. It can only do this if it has something tangible to hold up. Its called the GFA and the real and effective foothold the Irish State has in (some) affairs of NI through institutions established on a shared basis between Britain and Ireland.
But don't ask me, or SF for that matter, ask the FG'ers and the FF'ers who are pushing this stuff to Europe and to the British Government. In fact, all across the Irish political spectrum, with the exception of Irish Unionists and partitionists, that is the broad concensus.
Ergo, the Irish State as established and recognised by the Constitution is not limited to the 26 county state ( also described as The Republic of Ireland), it does in fact extend beyond the 26 county limitation that partitionists like your goodself and others here (who are popping out of the woodwork!)
Speaking of the EU, does the Irish State extend itself to European Institutions as well? I mean, how else are EU laws derived on Ireland without the authority of the Irish State sanctioning such laws? Isn't this the Brexit blackhole that Britain and EU have found themselves in Ireland?
