I hope so. Though 15 years may be a bit optimistic. The UK has passed through the phase of leaving the EU being a benefit in itself (freeing it up to rule the waves once again unfettered by the whims of politically-correct vino-drinking bureaucrats and such), and, faced with the sunk cost of its folly, has retreated into denial. Brexit may have cost us dearly, it goes, but it’s a price we have to pay to be true to our destiny, rather than pretending to be just another small country interchangeable with Spaniards and Belgians. Eventually the fit of pique will end and the consensus will settle on Brexit being a bit shite, and there not being any meaningful glorious destiny for which it is a price worth paying, and the question is how do we become like the Spaniards or Belgians (or, indeed, the Irish), enjoying the conveniences of the EU. It may take a generation though.
