Taking to Twitter to celebrate, Trump quoted a Fox News statement that North Korea passed on showing the missiles this year to demonstrate to him "its commitment to denuclearize", something which has been highly suspect at best.
North Korea has invited a large group of foreign journalists to cover a military parade and other events to mark the 70th anniversary of its founding.
According to footage broadcast from the scene by worldwide TV news crews, no Intercontinental Ballistic Missiles were on display - a concession nearly certainly aimed at the United States.
Mr Kim also referred to the June summit meeting with US President Donald Trump in Singapore, noting that he wants the US side to take action in proportion to North Korean efforts taken in accordance with their agreement in the summit.
Grace Liu, a research associate at the James Martin Center for Nonproliferation Studies in Monterey, California, said the low-key parade appeared to be aimed at maintaining a "relatively civil dialogue" with Seoul and Washington, especially given Moon's impending visit next week. "We will both prove everyone wrong!" he tweeted.
Instead, the country's ceremonial head of state Kim Yong-nam addressed the assembled crowd with a focus on economic development rather than nuclear might.
Despite no agreement yet between Pyongyang and Washington on the denuclearization process the two agreed to at their landmark Singapore summit in June, and with Pyongyang demanding the United States agree to a peace treaty to end the 1950-53 Korean War, there have, over the last week, been some encouraging signals. A running commentary throughout the show pointed out the importance of following Kim's economic and development strategy, while significantly playing down the role of the military and not once mentioning North Korea's nuclear weapons.
Xi said in the letter that the DPRK, under the successive leadership of Kim Il Sung, Kim Jong Il and Kim Jong Un, has made extraordinary achievements on the course of the socialist construction in the past 70 years.

He participated in four proffer sessions, they say, and "was willing to answer any questions posed". Papadopoulos was once described as a "coffee boy" to the Trump campaign.
Kim was seen laughing and holding hands up with a Chinese special envoy as he oversaw the festivities at Pyongyang's main Kim Il Sung square on a clear autumn day.
"All our might to build economy!" declared a banner atop a float decorated with modern trains, solar panels, wind power plants and hydro-electric dams.
Since I and the ABC News crew have been here, we have been with a government guide at all times, and can only go where they choose to take us.
This year's celebration, however, did not feature the isolated nation's most advanced missiles.
North Korea's state-run media published Friday what it said was an "indictment" by its South Korean wing, denouncing USA forces on the peninsula and calling their withdrawal "the irresistible trend of the times".
Thousands of dancers, gymnasts, martial artists and singers acted out scenes addressing familiar themes from North Korean propaganda, including the country's struggles to recover from the 1950-1953 Korean War, and a starvation in the 1990s.
No ICMBs were showcased in Pyongyang as the country celebrated its 70th anniversary on Sunday.
North Korea's alleged new missile would also be able to launch satellites into space - something Kim last did back in February 2016.
As the country launches a "new era" of reconciliation and worldwide engagement, Sunday's premiere in Pyongyang was the first Mass Games in five years and was a major part of a carefully choreographed weekend of events created to highlight Kim's diplomatic campaign and plans for economic development.
