To be fair today’s votes made it clear the problem is the backstop (despite claims by EU diplomats to the contrary after the last WA vote). So we should be able to make deals that don’t involve Ireland!
Thinking about this tonight this is yet another instance of the two sides not understanding each other. From the EU’s perspective the idea that NI being part of the EU was utterly critical (which maybe it was, I’m not saying this is necessarily wrong) to the peace process plays into the EU-as-peacebringer founding mythos, and so it becomes a moral imperative to maintain that state of affairs. From the UK side anyone with sympathy towards unionism in general (although not the DUP in specific) sees a deal that almost every unionist denounces and thinks that would be disastrous to the peace process, so it becomes a moral imperative to oppose it.
Certainly the Westminster tendency to try and ignore NI whenever possible has been hugely unhelpful.
That’s nonsense. The EU agreed to give all states the right to withdraw.
