The Irish politicians have had this put on them by the decision of the UK, instigated by UK politicians. Anyone who sticks to their guns on something, fair play to them. I view it as many UK politicians sticking to their guns to hide the fact they had no plan or idea of how this would work, or to hide the fact that they wanted no deal all along. If they are never going to back down, which is their right, then I don't see why Irish politicians (or any other nationality) should either. At the moment they have the backing of the other 26 members, I don't see why they should not use it to their advantage. Likewise, I don't see any problem with China in their stance with the USA, having had that trade spat thrown upon them by the other side. I would not have a problem with a club digging their heels in when it comes to the price of a player that we want to buy. Its their decision and their right to do so. Club allegiance does not mean i have to despise the other club because they ask for a high price, after the player renewed his contract only a few month before, and we unsettled him via his agent and secret meetings.
I would also point out that I don't think all 52% would vote the same again if it meant severing all ties with the EU. Culturally its easy, as we have the island mentality, but economically i think many of the 52% would think again. I'm still amazed the number of farmers who voted for it. I think knowing what they know now, many would change their minds. Same for people involved in the just in time manufacturing process. To be honest if there was another vote it might be even tighter.
Alarm bells - again, you and I will not see eye to eye. I trust the fact we have a veto. If that got taken away, then hell yes I would think again about remaining but then so would all members. It works because there has to be consensus and with 27-28 members, to find that all the time on all matters will be neigh on impossible, hence i'm not afraid of even closer union because i don't think all 27 would ever agree at the same time. You can leave the EU, Art 50 allows that. It was always an unknown as no one had done it. What we are living through is the product of it being described as very easy, but in practice it is not so.
