North Korea's 'CVID', or complete, verifiable, and irreversible denuclearization, had been the key goal for the Trump administration, leading up to the historic summit with North Korea, and its leader Kim Jong-un.
While the Singapore agreement calls for a 'complete denuclearization of the Korean Peninsula', the term CVID is glaringly absent.
Despite the omission, in an interview with ABC News, President Trump said he believes North Korea will abandon all their nuclear weapons.
"They've got to get rid of - yeah. They will. I think they will, I really believe that he will. I've gotten to know him."
Observers say 'complete denuclearization' falls short of the long-sought objective of CVID.
Others say the agreement was weaker than the pledge North Korea made in 2005, when Pyongyang committed to "abandoning all nuclear weapons and existing nuclear programs."
North Korea instead tested its first nuclear device the following year, and conducted five further underground tests.
While the summit agreement lacks the timeframe for North Korea's denuclearization and how this will be achieved in a way that is complete and verifiable, President Trump said in a press conference after the summit that follow-up negotiations will take place next week.
And while denuking North Korea will certainly come, it will take time.
"Well, you know, if you look at - if you talk to the experts, you can't ust do it immediately- it takes a period of time. well, somebody said 15 years, if you go rapidly, but when you're in a process of doing it, you're really dismantling."
Will the term 'complete denuclearization' be enough?
The focus now turns to next week's high-level follow-up talks between North Korea and the U.S.
Critics of the Singapore declaration will be looking for more specifics and concrete commitments and timeframes from Pyongyang.
