Oliver has spent the last year-and-a-half trying to discourage people from voting for Trump on his show, Last Week Tonight

'This is the most defiant nation on the planet Earth. The fact that some of you are sitting probably going "No, we're not," proves my point,' he said

While he said he couldn't guarantee everything would be OK now that Trump is President-elect, he said

Last Week Tonight host John Oliver hasn't had a show since before the election, but fans got an idea of his opinion on now President-elect Donald Trump at a benefit dinner the night after the vote.

Performing a set at the Natural Resources Defense Council's Night of Comedy benefit, Englishman Oliver sought to quell fears in the obviously liberal audience about what the Trump administration might bring.

Will America manage with Trump as chief executive? 'That's a difficult question to answer,' mused Oliver.

But in its favor, he proposed, is the fact that America is 'a defiant nation.' As an example of its national defiance, he reported that during the devastating financial crisis of 2009, Americans spent $310million on Halloween costumes - for their pets.

'You can't issue a stronger f*** you to a recession that that. It can't be done.

'You know what Greece was doing at that point don't you? Europe was basically united, reluctantly adopting crippling austerity measures and you were looking across at Greece and basically saying, "Well, good look with that Spiro. I hope that works out for you. But here's the thing, I'm pretty sure I can make my dog look like a bumblebee, so..."' Oliver joked.

In another example of American defiance, he recalled watching news reports on Hurricane Sandy, when news cameras caught footage of a person jet skiing through the storm in New York harbor.

'I guess I was trying to think of a way to tell you that everything is going to be OK. I'm obviously not practically sure I could do that. That depends who you are and what your definition of OK is. Looking out, most of you, fine,' Oliver joked
