We haven’t and will not undermined the GFA irrespective if we remain in the EU or not or if the UK/NI wants to abolish the WA in the future as the UK and Ireland have agreed to a CTA, remember the GFA dosn’t say the UK has to remain in regulatory alignment with the EU or anything about custom checks for goods at the border. The US can’t play that card either, but I imagine Pelli will twist to suit it’s own agenda just like the EU did in the beginning of the WA negotiations and May fell for it.
It is, indeed, accurate to say that the GFA doesn’t say the UK has to remain in regulatory alignment with the EU, or anything about customs checks for goods at the border.
It is equally accurate to say that EU rules and WTO rules would de facto customs / border checks. Even if it’s only on the Irish side and “an Irish imposition”.
Decision makers around the world aren’t numpties. They understand the causality here: no Brexit / Brexit + close regulatory alignment = no border requirement. Brexit + divergence = borders. You can try to blame the EU and Ireland, but it’s not lost on anyone that the EU and Ireland are not acting unilaterally, nor did they ever want to impose a border. Rather, it is a response to the UK’s democratic decision to wreck the status quo. Whatever follows is fallout from that decision. This is lost on, quite literally, no one.
It’s true that the UK can say that borders do not actually violate the GFA. But that is very much open to interpretation. Ireland will disagree. Pelosi will pounce.
Granted, it will have less to do with Ireland, and more to do with the Democrats mistrust towards nationalist populism, embodied by Trump, and through him, “Britain Trump”. The narrative around Brexit, especially on the Democrat side, is that Brexit and the Trump movement are inextricably linked, thanks, no doubt, to Bannon and Farage. The GFA just adds to Pelosi’s arsenal, given the role the US played in getting that deal done.
If Trump does not get re-elected, it might be even worse. Some of the reluctant / moderate Republicans in Congress will probably try to rinse their hands of Trump’s effort to remake the Republican Party. And their perception of Brexit as a Trump-ian movement (the merits of their view, or lack thereof, notwithstanding) probably won’t help the UK.
There’s a lot of variables at play here.
