Vice President Mike Pence warned Monday in a visit to the Demilitarized Zone dividing North and South Korea that the North Korean people and military "should not mistake the resolve of the United States of America to stand with our allies."
"The alliance between South Korea and the United States is ironclad," Pence said.
The vice president added that "the era of strategic patience is over."
Pence told reporters near the DMZ that the alliance between South Korea and the U.S. is "iron-clad" and is reiterating that "all options are on the table" to pressure North Korea to get rid of its nuclear weapons and missile program.
Pence visited a military base near the DMZ, Camp Bonifas, for a briefing with military leaders and to meet with American troops stationed there.
His 10-day tour of Asia comes as tensions grow in the wake of North Korea’s latest missile test.
