Fox News contributor John Bolton called Donald Trump’s speech before the United Nations Tuesday the best of his young presidency.

Bolton, who served as U.S. Ambassador to the United Nations under President George W. Bush, praised Trump for his direct denunciation of North Korea’s nuclear ambitions and criticism of the Iran nuclear deal brokered by the Obama administration.

“This was the best speech of the Trump presidency, in my view,” Bolton said. “I think he was as clear and direct as it’s possible to be.”

Trump said the U.S. would destroy North Korea if forced to defend itself or its allies; Bolton said that was a memorable line
