It comes as North Korea has been ramping up its missile technology with regular rocket tests, including two intercontinental ballistic missiles launches and its sixth nuclear bomb detonation earlier this year.
North Korea has also threatened to totally destroy the US and warned Donald Trump “should think twice about what terrible consequences the US will face”.
Speaking at Minot Air Force Base, in North Dakota, Donald Trump’s right hand man told the troops their commander-in-chief is depending on them to “be ready”.
Mr Pence said: ”Our enemies should never doubt the capabilities of the Armed Forces of the United States of America.
“Anyone who would threaten our nation should know that America always seeks peace, but if we are forced to defend ourselves or our allies, we will do so with military power that is effective and overwhelming.”
His remarks echoed the US Defence Secretary Jim Mattis, who warned North Korea should prepare for a US onslaught if it continues to escalate its war rhetoric.
The threat was issued by Mr Mattis after a visit to the demilitarised zone (DMZ) on the Korean border.
“North Korean provocations continue to threaten regional and global security despite unanimous condemnation by the United Nations Security Council.”
And while he said the US did not want to go to war with Kim Jong-un’s hermit state, he issued a clear military threat to the despot amid growing rumours of an imminent seventh nuclear test.
The Defence Secretary said: “North Korea provocations continue to threaten regional and world peace, and despite the unanimous condemnation by the United Nations Security Council, they still proceed.
“As the US Secretary of State has made clear, our goal is not war, but rather the complete verifiable and irreversible denuclearisation of the Korean Peninsula.”
It comes as a US Government source has revealed the despotic state secretly tested a new type of solid-fuel engine last week.
According to the source, the test took place at North Korea’s solid-fuel engine testing site in Hamhung.
And a senior CIA analyst warned that Donald Trump’s visit to China, Japan and South Korea in November could spark another provocation from Kim Jong-un.
Japan’s defence minister has also warned North Korea’s threat has grown to a “critical and imminent level”.
At the time the official added it “had not been decided” if Trump would visit heavily fortified demilitarised zone (DMZ) which separates the north and south.
