North Korea has consistently refused in past rounds of failed negotiations to provide an inventory of its weapons program and US intelligence remains uncertain of how many nuclear warheads North Korea has.
Pompeo told CNN late last month that he would not set a deadline for the denuclearization of North Korea and would "constantly reassess" whether enough progress is being made to continue negotiations. Recently, both leaders came into an agreement over nuclear production.
His National Security Advisor, John Bolton, insisted on Sunday that the administration was fully aware of North Korea's history of deception and was not entering the denuclearization talks naively.
Over the weekend, separate reports citing US officials seemed to confirm what so many experts have long feared - that despite the overtures and sunny proclamations made at the Singapore summit between President Donald Trump and North Korean leader Kim Jong Un, Pyongyang probably has little interest in dismantling its nuclear program.
Pompeo has already visited Pyongyang twice since April to meet with Kim - the first time when he was still director of the Central Intelligence Agency - and there are discussions about a possible third trip to North Korea late next week but such a visit has not yet been confirmed.
Calling out the Trump administration's "mishandling" of the nuclear negotiations, Maneshi said that it "is completely delusional and is more interested in the unjustifiable praise of a general conversation".
"There's no evidence that they are decreasing stockpiles, or that they have stopped their production", NBC quoted one USA official as saying.

Evidence of new efforts by North Korean leader Kim Jong-un to expand his nuclear arsenal underscore the challenge facing US President Donald Trump three weeks after declaring that North Korea was "no longer a nuclear threat". Commenting on these reports, Maneshi said there is "little doubt that business is going on as usual despite talks of peace".
Production of nuclear fuel has also ramped up while North Korea expands and improves a ballistic missile site.
"Our goal remains the final, fully verified denuclearization of the DPRK, as agreed to by Chairman Kim in Singapore", the spokesperson said, referring to the Democratic People's Republic of Korea.
"The North's nuclear cadre can be expected to proceed with business as usual until specific orders are issued from Pyongyang", 38 North said. And by the way I really believe North Korea has a tremendous future.
