US Vice President Mike Pence said on Monday during his visit to the Demilitarized Zone (DMZ) separating the two Koreas that the United States does not rule out any option to address the problems of North Korean ballistic and nuclear programs. 
Upon arrival at the inter-Korean border village of Panmunjeom inside the DMZ, Pence said "all options are on the table" although Washington wants to achieve security peacefully. He also called the US relationship with the South "ironclad and immutable". 
During his visit to Camp Bonifas, US-led UN base about 400 meters (438 yards) from the Demilitarized Zone, the US Vice President said "It is particularly humbling for me to be here. My father served in the Korean War with the US Army, and on the way here, we actually saw some of the terrain my father fought on alongside Korean forces to help earn your freedom." On Sunday, Pence strongly criticized North Korea's failed missile test, calling it a "provocation", according to (Yonhap) news agency. 
He also stressed US full support for South Korea in the face of threats from the North.
