I suggest that we are not that far apart in our assessments - we present them differently as we have different drivers as priorities and different outcomes as our desires.
Some comments on your points:
"It may well be that you are finally getting what you wanted on the negotiating table, and the threat of a no-deal, may or may not work."
Agreed - I have said many times versions of "We will not see movement from the EU unless and until they face the prospect of a viable walk-away option and the political will to use it". It is a simple factual statement that has been proven entirely correct IMO by events over the past 3 years - they have been able to just sit and observe the UK farce. BUT - even this does not mean that the other party will shift as much as you want them to - it just means that you make them consider/offer concessions that they are willing to as they wish to avoid the walk-away outcome. It means no more than that. They may end up being willing to offer substantial concessions or none at all - that does not detract from the truth of my view.
"However what I have repeatedly maintained is that the Irish government stance is the only one that actually seems to have the backing of the island of Ireland"
I can accept that - certainly the UKs stance does not.
Also, I suggest that there should be recognition in Ireland that the UK has made a sovereign decision to exit from the EU - and a level of acceptance/respect shown towards that determination.
The path should have been that, immediately following the referendum, representatives of Ireland and the UK were established as a joint group to 'calmly and in a spirit of goodwill' consider the implications for the GFA and to be tasked with identifying the key issues and bringing forwards proposals/processes/workarounds to ensure that changes, acceptable to both sides, could be determined, planned and implemented.
"What you describe above is a strategy. A strategy that you have advocated all along.
Your point No 1. above demonstrates to me that you are fully aware that the language you used repeatedly in here was part of that strategy.
The EU need to be seen as bullies!"
Entirely correct - one that recognises the here and now issues presented by the lack of representation of the English element of the UK at parliament and one that seeks to plot a path for the referendum result to be implemented. It is not going to be implemented in the current climate - the cadre of Remainers are just waiting for it all to fizzle out and be overturned by a 2nd vote.
I put forward a path that allows for N.I. self determination through a referendum with the options being either an Irish Sea border but remaining part of the UK or unification (be careful what you wish for). I include a path for self-determination in Scotland through an Indyref2 vote - although I make clear that I feel that Scotland will vote to remain in the UK by an increased majority - which I am surprised some have not challenged.
There is though a prevailing set of narratives that are disregarding of the rights of England. Irish and Scottish nationalism is presented as noble - that there should be any consideration of what English people want is dismissed - but there was a massive majority in England for Leaving the EU
So, you are right, what I set out is a strategy to resolve the situation - personally I would suggest that they are actually sensible steps - to be successful there needs to be a narrative that positions the EU as the bad guy and takes advantage of a window during which the Remain vote will be split.
"I appreciate your view and it's not a criticism of your tactic or the tactic that you feel should have been employed, but I regard this strategy to be 'weaponising' (your word) Northern Ireland and the GFA more than anything you regard the EU to be doing"
You and other posters based on the Island of Ireland have understandably taken issue with this POV. I maintain that it is correct - for me it is entirely self-evident because otherwise we would jointly be doing what I suggest in my 2nd comment above. You may think that the EU are being altruistic - I certainly do not. I repeat it because, just like how a no-deal option should be used, some posters clearly do not understand it. There are some posters on here - not from the island of Ireland - that bang on in a manner as if the GFA is and always has been sacrosanct to them - when it fact it is just 'cover and code' for - this can be used to stop Brexit.
