Absolutely. As @JPRouve said, the loss of trust and respect now runs so deep it's hard to see how anyone in this generation of EU politicians would want to go through negotiations again with such a bad faith operator.Agree with @JPRouve . I'd love to rejoin tomorrow if we could and have said before I personally have no issues with closer political union etc etc. But I can't see any way in which we rejoin the EU in a generation.
Both from the UK perspective (there's still a hardcore significant Brexit component in the UK and always will be, people won't want to admit they're wrong and I've noticed even people who are very pro-Europe generally are finding themselves a bit aggrieved at times because of the inevitable friction between the UK and EU, any rejoin referendum would be similarly slim margins imo) and from the EU perspective (we've always been an awkward member, we've caused everyone a lot of headaches in the last 5 years, even most of the pro-EU lot in the UK are generally not as pro closer political integration).
Yes we'll be a loss economically, culturally, politically etc to the EU but peace of mind probably will be significantly better for the EU and they can carry on with their business without one of their largest and most important members always throwing up roadblocks.
Brexit is still somehow being championed as a success and if we were to rejoin, wouldn't we need to adopt the euro? Can't imagine that happening.
