U.S. Ambassador to the United Nations Nikki Haley said on ABC's This Week that President Donald Trump's unpredictability is in part what keeps foreign leaders "cautious" and "paying attention" to how they relate with the United States.
"I think they don't know what the U.S. is going to do at any given time, and so for that reason they're getting much more cautious and they're paying attention to how they work with us," she said. "So, you know, we've got a ways to go, but it's not a bad thing, it's really not."
Haley also defended Trump's January 2 tweet bragging that his nuclear button is bigger than the one on Kim Jong-un's desk:
"We want to always remind them we can destroy you too, so be very cautious and careful with your words and what you do," she said. "I know it's something that makes people nervous but if we didn't do it, we would be in a more dangerous..."
As for Trump's tweet, she said, "I think that he always has to keep Kim on his toes. It's very important that we don't ever let him get so arrogant that he doesn't realize the reality of what would happen if he started a nuclear war."
