Great Britain has followed Donald Trump's advice and given the establishment the finger. The popular revolt will have political and economic repercussions for decades to come, not least of which on this year's already astonishing US presidential election.

In what is perhaps the most momentous day in British politics since Word War II, Britons shocked the world with their decision June 23 to end their 43-year marriage of convenience with the European Union. The vote had an immediate impact on the US race, with Trump hailing the result as a triumph of nationalism and Democrat Hillary Clinton warning of the risks it posed to global economic security.

In Scotland to visit one of his golf courses, Trump, the presumptive Republican nominee, embraced the vote as vindication for his own platform of robust nationalism and immigration control. "Basically, they took back their country, that's a great thing," Trump said. "They're angry over borders. They're angry over people coming into the country and taking over, and nobody even knows who they are."

Other anti-establishment figures echoed the sentiment.
