Mr Pompeo also praised Mr Trump for bringing home Americans held hostage in the rogue state. He did so on Tuesday during a rare address at the Republican Party’s National Convention.
Mr Pompeo was the first sitting US secretary of state to address a national party convention in at least 75 years.
By doing so, he broke with a long-established practice of secretaries of state avoiding domestic politics.
He said: “I have a big job – as Susan’s husband and Nick’s dad.
“Susan and Nick are more safe, and their freedom’s more secure because President Trump has put his America First Vision into action.
“In North Korea, the president lowered the temperature and, against all odds, got the North Korean leadership to the table.
“No nuclear tests, no long range missile tests, and Americans held captive in North Korea came home to their families, as did the precious remains of scores of heroes who fought in Korea.
“Today, today because of President Trump, NATO is stronger, Ukraine has defensive weapon systems, and America left a harmful treaty so our nation can now build missiles to deter Russian aggression.”
In the pre-recorded message, Mr Pompeo added: “This President has led bold initiatives in nearly every corner of the world.”

“Those jobs, those jobs are coming back home.”
He added: “The president exited the US from the disastrous nuclear deal with Iran and squeezed the Ayatollah, Hezbollah, and Hamas.
“The president too moved the US embassy to this very city of God, Jerusalem, the rightful capital of the Jewish homeland, and just two weeks ago, the president brokered a historic peace deal between Israel and the United Arab Emirates.
“This is a deal that our grandchildren will read about in their history books.”
During his speech, Mr Pompeo also praised the Trump-approved strike that killed top Iranian general Qasem Soleimani.
Of Qasem Soleimani, Mr Pompeo said: “This is the man most responsible for the murder and maiming of hundreds of American soldiers and thousands of Christians across the Middle East, and you’ll recall too, that when the president took office, radical Islamic terrorists had beheaded Americans and ISIS controlled a territory the size of Great Britain.
“Today, because of the president’s determination and leadership, the ISIS caliphate is wiped out, it’s gone.
“It’s evil leader, Abu Bakr al-Baghdadi, is dead and our brave soldiers, they’re on their way home.”
