-- Vice President Mike Pence declared an end to what he called a policy of "strategic patience" on North Korea during a surprise visit to the Demilitarized Zone on his trip to South Korea.
"The era of strategic patience is over," Pence said. "President Trump has made it clear that the patience of the United States and our allies in this region has run out and we want to see change. We want to see North Korea abandon its reckless path of the development of nuclear weapons, and also its continual use and testing of ballistic missiles is unacceptable."
Pence landed via helicopter at Camp Bonifas, about a mile from the southern boundary of the zone. He received a security briefing from Gen. Vincent Brooks, the commander of U.S. Forces Korea, and then visited the Freedom House observation post in the DMZ.
Briefly addressing reporters in Camp Bonifas, Pence praised the "unshakable bond" between the U.S. and Korean people.
