Sorry - missed another bit.
"The Republic of Ireland has no right to require a change of regime in Northern Ireland. Nor have its citizens."
This is what is under dispute at the present time and you, as a British citizen, have no right to proclaim on the rights of any coutnry as to what say it has on the question of parttioning its own territorty - be in Viet Nam, Cyprus, Mainland and offshore China, India and Pakistan..... wherever
Eighty eight years ago the British Government imposed partitioning (supposedly temporarily) on the island of Ireland under threat of invasion, and the result was a god-awful sectarian mess - one we are still living with.
The Republic has far more right than the UK to say whether that partitioning remains or how the problems that it brought should be resolved.
British mis-governance of Ireland has lasted for centuries and its ham-fisted efforts to suppress the effects are still leading to bloodshed and disunity.
