In the New York Times, London correspondent Steven Erlanger suspects the result has left many Britons in a state of existential anxiety.
"Will Britain be the outward-looking, entrepreneurial, confident country that makes its independent way in the world, as the leaders of the 'Leave' campaign insisted it could be?

"Britain, a nation whose storied history has encompassed the birth of constitutional government, global empire, royal pageantry and heroic defense against fascism, is entering unknown territory," he says, predicting adding that "the questions about its new path could remain unresolved for years.
