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. He insisted that Trump had been explicit about the sequencing from the start. "We're hopeful that we can achieve that in the two and half years".
Meanwhile, Pompeo has to reassure Seoul and Tokyo that US concessions in the talks with North Korea won't erode the USA security umbrella that for decades has protected allies in northeast Asia. -South Korean military exercises - long a demand of China and North Korea, and until this week a non-starter for Washington - without apparently consulting South Korea or the Pentagon.
Pompeo will meet President Moon Jae-in on Thursday morning to discuss the summit.
Earlier in the day, Trump declared that there is 'no longer a nuclear threat from North Korea'.
Pyongyang in return "commits to work toward complete denuclearisation of the Korean peninsula".
But the details of what is sure to be a complex and contentious process have yet to be settled.
The move - long demanded by Pyongyang - has been seen as a major concession to North Korea and appeared to take United States allies in the region by surprise. "The Korean War never ended, it was a cease-fire and now we have a chance to put that conflict to bed".More news: Toddlers could be consuming more sugar than recommended for adults, study finds
Of the world's eight known nuclear powers beyond North Korea, three - India, Pakistan and Israel - emerged outside a formal worldwide arms control framework.
Trump also agreed to halt joint military exercises between the US and South Korea on the Korean Peninsula, though that decision seemed to surprise both Seoul and the Pentagon. It called the summit "dumbfounding and nonsensical", and said it will allow North Korea to permanently maintain its nuclear weapons program.
Pompeo will then travel to Beijing, North Korea's main diplomatic ally.
Pompeo, the former Central Intelligence Agency director, planned to fly to Beijing later Thursday to update the Chinese government about the talks. Chris Murphy, D-Conn., and Tammy Duckworth, D-Ill., would prevent Trump from withdrawing troops from South Korea unless the secretary of defense says it's in the interest of national security and that it would not undermine the security of allies in the region.
Just months ago, Kim and Trump were trading threats and personal insults as the North conducted its sixth and most powerful nuclear test.
"The United States is our ally, so the joint military drills are still necessary to maintain our relationship with the USA", said Lee Jae Sung, from Incheon. The words came back to haunt the administration, as the war dragged on throughout Bush's presidency.More news: Negotiators scramble to put something together for Trump and Kim
The summit statement provided no details on when Pyongyang would give up its nuclear weapons programme or how the dismantling might be verified.
Trump's claim is dubious given that independent experts estimate Pyongyang has enough fissile material for 20 to 60 bombs.
The exact terms of that agreement remain unclear.
He noted: "From what we know from our reports there were a number of attacks prior the summit from North Korea focused on South Korea". "President Obama said that North Korea was our biggest and most risky problem".
But he said that was no longer the case, and everyone can "sleep well tonight".
Seeking to quell concerns that North Korea and the USA interpreted the talks differently, Pompeo said, "I am confident that [North Koreans] understand what we're prepared to do".
"Let's see if I have this straight", she said. -South Korea military exercises, handing North Korea a win on one of its longtime policy goals.

"He (Trump) made it very clear that the condition precedent for the exercises not to proceed was for productive, good faith negotiations being ongoing", Pompeo told reporters. He told reporters that if the US concludes they no longer are, the freeze "will no longer be in effect".
