The United States joined around three dozen other nations in boycotting a conference at the U.N. on a treaty to ban nuclear weapons. Other nations boycotting the five-day talks included Russia, China, Great Britain, France, South Korea and Albania.

U.N. Ambassador Nikki Haley warns about the threat of nuclear weapons. “But in this day and time, we can’t honestly say that we can protect our people by allowing the bad actors to have them and those of us that are good trying to keep peace and safety not to have them.”
