The Trump administration Monday delivering a warning right on North Korea's doorstep, as Vice President Mike Pence said: Don't test us. He was speaking after a visit to the demilitarized zone.

FOX's Alastair Wanklyn reports:

Vice President Mike Pence saying the U.S. wants a denuclearized Korean peninsula, but it's unwilling to sit around and wait:

(Pence) "We hope to achieve this objective through peaceable means. But all options are on the table."

He said talks with North Korea are still possible. But should Pyongyang reject this, it should note the strikes President Trump ordered recently in Syria and Afghanistan:

(Pence) "North Korea would do well not to test his resolve or the strength of the armed forces of the United States in this region." 

The Vice President speaking after a visit to the DMZ, where he got a situational briefing and was observed by North Korean guards.
