Donald Trump said last week he’d be willing to meet with North Korean leader Kim Jong Un to try to deflate the nation’s nuclear ambitions peacefully. On Monday, the message from the Hermit Kingdom to the casino magnate and presumptive GOP nominee was: No deal.

So Se Pyong, North Korean ambassador the United Nations, left some wiggle room for later by saying “it is up to the decision of my Supreme Leader whether he decides to meet or not.” Having got that out of the way, the diplomat said frankly that Trump’s “idea or talk is nonsense.”
