Just over half of all Americans say they approve of how President Donald Trump has handled North Korea, but only a quarter think that his summit this week with Kim Jong Un will lead to the denuclearization of the Korean peninsula, according to a Reuters/Ipsos opinion poll released on Wednesday.
Pompeo said he expects the United States would next speak to North Korean officials "fairly quickly after we return to our home countries", adding he was "very confident" that some form of engagement would occur in the next week.
While Trump and Kim concluded their summit in Singapore by signing a joint statement that promised "complete denuclearization of the Korean Peninsula", it did not specify what that process would entail.
But it "all depends on whether North Korea is serious about denuclearization". "Only then will there be relief from the sanctions".
On Twitter, in letters and in person with Kim Jong Un in Singapore on Tuesday, Donald Trump made clear his belief that the fate of North Korea hinges on a personal relationship between the two men.
Last year's talking point was that Trump, with his "fire and fury" talk, was leading the USA into a nuclear war with North Korea.
Pompeo said Trump was alluding to the fact that it was the first time a sitting US president had met with Kim, adding that both leaders had a "blunt conversation" about the need for the communist state to rejoin the world community.
Pompeo will meet President Moon Jae-in on Thursday morning to discuss the summit.
Actually, concerns about North Korean missiles and nuclear weapons reached a peak last year, during Trump's first year in office, as the North conducted more tests and Trump and Kim aimed ever more fiery rhetoric at each other.
"Not all of that work appeared in the final document", Pompeo said.

The exercises are meant to ensure that South Korean and USA troops are ready to respond to sudden North Korean aggression.
Trump has sought to portray his unprecedented meeting with Kim as a significant accomplishment that has made the world less vulnerable to the North's nuclear arsenal.
Now a top analyst with United States Institute of Peace, Mr. Yun told CNN on Tuesday that halting joint U.S. -South Korea military exercises, handing North Korea a win on one of its longtime policy goals.
Former U.S. ambassador Bill Richardson told VOA he is concerned about no verification of what the North Koreans will do about missile technology in their country, no details of nuclear reduction or the peace treaty ending the Korean War from the early 1950s, and human rights. Trump cast that decision as a cost-saving measure, but also called the exercises "inappropriate" while talks continue.
"So that's good for a number of reasons, in addition to which we save a tremendous amount of money", Mr Trump said.
The U.S. has stationed combat troops in South Korea since the end of the Korean War and has used them in a variety of drills.
This is not the first time Trump has declared the news media an "enemy" of the United States, as previous year he said that networks that covered him critically were an "enemy of the people". He said he planned to continue sharing the view with Washington and Seoul.
