A quick answer: Probably not.
Pompeo said Wednesday that Trump "made it very clear that the condition precedent for the exercises not to proceed was productive, good-faith negotiations being ongoing".
But others said it's a great step forward for peace.
He acknowledged that many difficulties are likely to lie ahead but vowed to work together with the U.S., North Korea and others to bring lasting peace to the Korean Peninsula. "And the issue is now, where do we go from here - whether we can maintain momentum from the summit and start putting flesh on those bones". The latest example concerns North Korea.
KCNA said the United States president expressed his intention to offer security guarantees to North Korea and lift sanctions "over a period of good-will dialogue" between the two countries.
"High expectations were met by low results", said Nam Sung-wook, a North Korea expert at Seoul's Korea University.
The U.S., which now has 28,500 troops stationed in South Korea, has maintained a combat force on the peninsula since the end of the 1950-53 war and has used them in a variety of large-scale drills created to sharpen skills and test troops' ability to operate effectively with their South Korean partners.

"You know, we spend probably 25 percent of our time talking about Russian Federation and I said wouldn't it be better if they were here", Trump said.
"North Korea still has all its nuclear missiles, and we only got a vague promise of future denuclearisation from a regime that can't be trusted".

However with her massive CV of humanitarian and Hollywood work as well as Harry by her side, we bet she'll do just fine. It's official! The new royal couple exchanged their vows at a royal ceremony at Windsor Castle, near London, in England.
"Why did South Korea and the US form an alliance and stage military drills before the nuclear crisis flared?" "I said, I have something to say from North Korea".
Asked to respond to Trump's decision, Moon spokesman Kim Eui-kyeom said the allies must consider a "variety of ways to further facilitate dialogue" during the nuclear negotiations. He said South Korea is still trying to figure out the exact meaning and intent of Trump's comments.
North Korea still has nuclear weapons.
A Chinese plane with Kim on board touched down at Pyongyang International Airport at 7 a.m., according to Korean Central Television and Pyongyang Broadcasting Station (PBS).
After successful cooperation at the Olympics, Moon sent special envoys to North Korea who later traveled to Washington with Kim's proposal for a summit with Trump.
Pyongyang in return "commits to work toward complete denuclearisation of the Korean peninsula".
During his talk with Hannity, Trump said his inflammatory rhetoric helped spur this new meeting.
Analyst Hong Min at Seoul's Korea Institute for National Unification said critics of the joint statement signed by Trump and Kim are missing a bigger point.
Ordinary North Koreans consistently voice unequivocal support for the leadership when speaking to foreign media.
In his post-summit press conference, Mr Trump made the surprise announcement that the USA would halt joint military exercises with its security ally Seoul - something long sought by Pyongyang, which claims the drills are a rehearsal for invasion.
