A Brexit Choice Between Bad and Worse

Theresa May's government is still promising to quit Europe's customs union when Brexit happens next year. The prime minister's position is politically understandable, yet entirely indefensible. And it perfectly captures the bind Britain has gotten itself into.

Staying in the European Union's customs union after Brexit, or joining some specially tailored version of it, would leave the U.K. with a worse deal than the one it currently enjoys as a full member of the EU. All Remainers think so, and a good many Leavers would probably agree. Proposing such an outcome comes close to admitting that the whole Brexit project has gone wrong. It has gone wrong — but, understandably, that's something May and her colleagues are unwilling to say.
