U.S. Ambassador to the United Nations Nikki Haley defended President Donald Trump's speech to the United Nations General Assembly and his new nickname for North Korean dictator Kim Jong Un: "Rocket Man."

On “Good Morning America​," Haley said the most important thing about Trump's "Rocket Man" remark is that "it worked."

“This is a way of ​getting people to talk about​ him,” Haley said.​ ​”Every other international community is now referring to him as ‘Rocket ​M​an.'”

Steve Hilton appeared on "Fox & Friends" this morning to react to the criticism Trump is receiving for his new label for Un.

"You have all these people at the UN and all these foreign policy experts who are going, 'You shouldn't speak like this. You should be more diplomatic.' These great 'experts' in foreign policy, they're the ones who have caused all these problems, that let North Korea get to this point," Hilton said.

He explained that the policies of these "great geniuses" enabled North Korea's nuclear program and "left the world in a mess."
