LONDON — Brexit. Brexit? Brexit! BREXIT!? The Backstop! Norway Plus! Canada Minus? The Cooper Amendment! The Malthouse Compromise? The Kyle-Wilson Amendment! Hard Brexit! Soft Brexit! No deal? Brexiteer! Remoaner! BREXIT!!?? Aaaargh.

It has come down to this with a few weeks to go until the March 29 deadline for Britain to leave the European Union, as it voted to do almost three years ago: a jumble of jargon, jousting and gibberish, with everyone sucked into the vortex of confusion, to the exclusion of every other issue in the world. Britain’s biggest political parties are splintering, and there is clarity only on the fact that nobody has a clue what is about to happen.

So much for the panacea offered in 2016 by leaders of the Vote Leave campaign — a land of milk and honey in which an island liberated from European shackles would become “Global Britain,” money would flow, impetigo would be cured, children would become more beautiful, the soil more bountiful, and the world Britain’s oyster. These days, the fantasy has sagged into a mumbled, “Well, Brexit is not the end of the world.”

Not quite. “Leaving and going somewhere are not the same thing,” Sam Gyimah, a Conservative politician who quit the government of Prime Minister Theresa May late last year in protest at her proposed accord with the 27-nation European Union, told me. “Nobody agrees on where we should go.”
