"I don't view it as a failure at all when American national interests are protected", Bolton added.
Last week, Trump and Kim met in Hanoi for their second summit to try to negotiate a deal on North Korea's denuclearisation but the meeting ended with the United States president walking away from the negotiations empty-handed.
Much of the criticism of the summit was sparked by Trump's remarks on the case of an American student tortured and left in a coma in North Korea.
His comments came days after the Feb 27-28 denuclearistion summit between Trump and Kim broke down over differences on how far North Korea was willing to limit its nuclear programme and the degree of United States willingness to ease sanctions.
"He's not desperate for a deal, not with North Korea, not with anybody if it's contrary to American national interests", Bolton said.
On a jarring note, the NIS said that it detected signs of the North restoring part of the Dongchang-ri missile launch site it tore down.
Cohen, Trump's former personal attorney, testified before the House committee on government oversight on February 27.
"There is nothing that restricts North Korea's ability to do testing of its ballistic missiles", he says.

Moon said South Korea will continue to push ahead with engagement with North Korea within the boundaries of US -led worldwide sanctions against the North. Tapper asked the national security adviser.
"It's unfortunate because this was one of the unilateral steps that the North Koreans were making at the beginning of the negotiation process as sort of a confidence-building measure, and so certainly this does have implications for how the North Koreans are thinking about the negotiation process", Town said.
The measure, which would deny access to the US banking system to any foreign bank that does business with North Korea, unanimously passed the Senate Banking Committee a year ago but did not advance further.
The U.S. maintains some 28,500 servicemembers in South Korea, which remains technically at war with the North after their 1950-53 conflict ended in an armistice instead of a peace treaty.
Trump took to Twitter later Sunday afternoon to defend his decision on the military drills, stating that the reason for canceling them was "to save hundreds of millions of dollars for the USA for which we are not reimbursed".
"I believe that dialogue between the two sides will eventually lead to a settlement", he said, but stressed that "a prolonged hiatus or impasse in dialogue is never desirable".
"That was my position long before I became President".
At the meeting, South Korea's Foreign Minister Kang Kyung-wha said the proposed talks, which could include civilian experts from the US and South Korea, would help settle differences over how much sanctions relief Washington should provide to North Korea in exchange for nuclear disarmament steps.
