In an interview with Reuters, President Trump warned of a "major" conflict ahead with North Korea. But at the U.N. the next day, Secretary of State Rex Tillerson called for negotiations and asked other countries to apply diplomatic pressure. Margaret Brennan reports on the administration's strategy.
As President Trump raises the real possibility of "major conflict" with North Korea over its nuclear and missile programs, the U.S. is putting on a show of force intended to convince the regime that it doesn't stand a chance against the American military.
