I actually kind of agree with Devilish here, maybe not the way he words it but the sentiment behind what he's saying.
At the end of the day, Austria, Belgium, Bulgaria, Croatia, Republic of Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Poland, Portugal, Romania, Slovakia, Slovenia, Spain and Sweden do not give a feck about the GFA, or have any need to care about it. It isn't their problem, it's a problem that exists between the UK and Ireland. Nor should they be required to pander to us, because we didn't sort it out properly. It's not their issue that we as a country decided to do something that puts the GFA in jeopardy. Nor should we be able to hold someone hostage because of our own internal issues.
Ireland didn't ask for this, nor did any other EU country. We're the ones who decided to go ahead with something that we knew well in advance would put it in jeopardy and as such it's our sole responsibility to sort the issue out. The fact that we haven't is testament to how fecking useless our government is and as much as I agree with you about the importance of the issue and that it absolutely has to be handled because nobody wants that history dragged up again, and nobody wants anyone to start shooting at a border, the fact remains that 26 other countries shouldn't be required to endure a tedious will-they, won't-they for years from a country throwing their toys out of the pram about a multitude of issues not just the GFA that they should have thought about and found a solution for before they decided to go full steam towards Brexit.
I'm pro-remain all the way, and I welcome absolutely any delay to the Brexit process with the hopes that it gets cancelled fully but I think it's a valid point of view from the majority of the EU that this isn't their problem to deal with, and that how delicate this issue is is just testament to how much we should have thought about this before we decided to cut our nose off to spite our face and that their patience for our stupidity can only stretch so far before they have every right to say 'you know what, feck it you've had way more than long enough to sort your shit out and we are all collectively tired of enduring this saga whilst you do absolutely nothing as a government to sort out the troubles that you need to avoid.'
We knew at the time we were voting for Brexit that the GFA was at risk, it should have been the government's main objective from day one post referendum and not left so late. All blame here should be directed at our government, and not anybody in 26 other EU countries who are getting tired of us.
