Britain, into chaos leaping?

LONDON — The poet Rupert Brooke voiced the exhilaration of those Britons who welcomed the war in 1914 as a chance to escape monotonous normality, “as swimmers into cleanness leaping.” They got four years mired in Flanders’ mud. In a 2016 referendum, Britons voted, 52 percent to 48 percent, for the exhilaration of emancipation from the European Union’s gray bureaucratic conformities. They thereby leapt into a quagmire of negotiations with an EU determined to make separation sufficiently painful to discourage other nations from considering it.
