John Oliver compares Trump's Iran deal stance to a cat on an airplane

When faced with a "will he, won't he" question, Trump always picks the worst answer, and John Oliver is here to explain his next big mistake.

On Last Week Tonight last night, Oliver talked about Trump's upcoming Iran Deal decision, why Trump hates the Iran Deal so much, and what would happen if he kills it.

It's hilarious yet disturbing.

Oliver first points out how much Trump pretends to know about the Iran Deal, with clips of Trump citing elements of the deal that don't exist. 

"Let's be absolutely clear here, Donald Trump has never studied anything in great detail," Oliver said. "If you asked him what color his wife's eyes are, he would say '34D, but firm.'"

Oliver then focuses on the biggest issues Trump has with the Iran Deal, one of which being that it expires in 10 years, which will be a problem when the time comes. This sends Oliver into a frantic rant about how if Trump kills the deal now, 0 years is much less than 10 years in working through that problem.

He also berates Trump for thinking that he can just be against something without any plan for what comes afterward, comparing Trump to a cat on an airplane trying to escape its carrier. "OK, but if you get out, then what?"

Trump is set to make his decision on the Iran Deal by May 12, and unless he completely changes his mind on it, Oliver says, he will probably kill it.
