"The dispersed deployment of these bases and distinctive tactics employed by ballistic missile units are combined with decades of extensive camouflage, concealment and deception practices to maximize the survival of its missile units from pre-emptive strikes and during wartime operations", they said. Analysts say the answer is no - although there are plenty of caveats.
According to Mark Fitzpatrick, from the International Institute for Strategic Studies, the findings did not come as a surprise.
What Happened: Satellite imagery indicates North Korea is continuing activity at at least 13 undeclared missile bases, including some construction activity, the Center for Strategic and International Studies reported November 12.
It says they will continue them.
The findings, which were released amid signs the administration's negotiations with the North have stalled, draw on commercial satellite imagery and identify 13 secret facilities used to produce missiles and related technology.
It points to the existence of a base at Sakkanmol which is capable of holding medium-range ballistic missiles.
The CSIS report comes after analysts writing for 38 North reported "minor cleanup activity" at North Korea's Punggye-ri Nuclear Test Site, which was detonated earlier this year before an global press corps.
After a tense 2017, diplomacy produced a thaw at the start of this year.
North Korea is conning the United States, building up secret, smaller missile bases even after publicly touting the dismantling of its main launch site, according to a new review of satellite images by a top think tank. Senator Edward Markey, a Democrat member of the Foreign Relations Committee, said on Monday that "President Trump is getting played by Kim Jong-un".
North Korea has for a long time slammed joint military exercises between the USA and South Korean forces as rehearsals for invasion, and regional tensions nearly every year had escalated around spring. In public, he has largely kept this positive view of negotiations. "If the second summit blows up, then maybe we see a resumption of testing and fire and fury".
This comes after North Korea canceled a meeting with Secretary of State Mike Pompeo last week, with outgoing United Nations Ambassador Nikki Haley explaining the north was "not prepared" for the talks.
Duyeon Kim, an adjunct senior fellow at the Centre for a New American Security, said while these developments violate UN Security Council resolutions, they do not breach Kim's agreement with Trump.
But to some analysts, North Korea never explicitly agreed to that, only to the more vague term "denuclearization".
Less than 24 hours before Pompeo was scheduled to travel to NY for those meetings, the State Department announced they had been postponed because of a scheduling conflict.
"North Korea's decommissioning of the Sohae satellite launch facility, while gaining much media attention, obscures the military threat to U.S. forces and South Korea from this and other undeclared ballistic missile bases", CSIS said.
He vowed to work towards denuclearisation during his historic June summit with U.S. President Donald Trump, but Pyongyang's actions have fallen short of U.S. demands for irreversible steps to scrap its arsenal, including a full disclosure of nuclear facilities and materials.
North Korea has removed 636 land mines from Panmunjom, on the border with South Korea, South Korean Defence Minister Jeong Kyeong-doo said Monday.
However, he added, the report could also make the current stalemate between Washington and Pyongyang last "longer than expected".
