Three years after the British people voted to leave the European Union, Britain is still stuck. Prime Minister Boris Johnson’s threat to leave without a formal Brexit deal has triggered a crisis in Parliament. Behind this commotion is an intransigent E.U., mindful that without the threat of a “no-deal” Brexit, the U.K. has no bargaining power. Christopher Caldwell, writing in The Claremont Review of Books, deftly fills in the blanks on the Brexit debate, especially regarding the Eurocrats. The E.U.’s ability to evade democratic responsibility, Caldwell warns, may be even more robust than its most vocal critics feared.
