John Oliver Blasts Results Of Brexit Referendum, Warns US Could Be Next

Comedian John Oliver had warned that Britain voting to leave the European Union in the Brexit referendum would be a "disastrous mistake." Suffice to say, he was not happy with the outcome.

Oliver's home country voted to leave the EU by a vote of 52 percent to 48 percent in Thursday's referendum. On HBO's "Last Week Tonight" Sunday, Oliver blasted his compatriots for not heeding his advice.

“Let us begin straightaway with the United Kingdom, a place whose very name after this week’s events is beginning to sound a bit sarcastic,” Oliver said. “The U.K. this week voted to leave the European Union, a decision that has shaken the world — and not in a ‘Muhammad Ali beating Sonny Liston’ kind of way, more in a ‘Those IKEA meatballs you love contain horse kind of way.’ The fallout in Britain has been swift and significant.”

The comedian ticked off the many consequences of Britain's landmark vote, including the massive hit to financial markets and the resignation of Prime Minister David Cameron. He then took aim at Boris Johnson, the pro-Brexit, former London mayor who is angling to be Britain's next prime minister. Oliver criticized Johnson, whom he described as a “shaved orangutan with Owen Wilson’s hair," for stoking immigration fears and referring to Brexit as Britain's "Independence Day."

“First, Britain was already independent. In fact, it’s what many other countries celebrate their independence from,” Oliver noted, before drawing a comparison to the "Independence Day" sequel that hit theaters over the weekend. “The sequel to the movie they’re quoting actually opened this week and features the wholesale destruction of London – which is beginning to feel pretty f------ appropriate now.”

Oliver warned that America could fall victim to the same kind of reactionary decision in the 2016 presidential election, implying that Donald Trump's presidential campaign is fueled by similar motivations to the campaign to leave the EU.

"You might think that is not going to happen to us in America," Oliver said. "Well, let Britain tell you: It can happen, and when it does, there are no do-overs."

Oliver had previously urged Britain to reject Johnson and others' calls to ditch the EU.

"A Brexit could have wide-ranging implications not just for the U.K. but for the rest of the world's economy," Oliver said on "Last Week Tonight" just days before the June 23 referendum. "Immigration policy may not change, hysteria over regulation is a red herring, the cost of membership is reasonable, and the economic benefits of staying appear to outweigh the costs. And yet polls suggest that my homeland is on the edge of doing something absolutely insane."
