CONTRASTING VIEWS ON NORTH KOREA UNDERSCORE SENSITIVITIES AND LACK OF EVIDENCE

WASHINGTON — On the hawkish end is the Pentagon’s intelligence arm, the Defense Intelligence Agency, which fears that North Korea could threaten American troops with a nuclear weapon on a crude missile. On the skeptical end is the State Department, which has more doubts about Pyongyang’s capabilities. And somewhere in the middle is the Central Intelligence Agency.
Those contrasting views are vying with one another in the intelligence community, and a hint of those differences came into rare public view on Thursday when an assessment by the Defense Intelligence Agency that it has “moderate confidence” that North Korea has the ability to shrink a nuclear weapon and fit it into a missile warhead surfaced at a Congressional hearing. That conclusion was disputed by James R. Clapper Jr., the director of national intelligence, who issued a statement later in the day saying that it did not reflect “the consensus” of the nation’s intelligence community.
The contradictory statements and sudden round of finger-pointing seemed to underscore once again the difficulty of obtaining reliable information — and making educated guesses — about one of the world’s most closed societies. But it also highlighted the sensitivity surrounding intelligence estimates in the wake of the highly publicized intelligence failures leading up to the Iraq war, and some subsequent failures involving North Korea.
“The situation is that there is so little direct evidence that I don’t think it’s possible to come to a firm conclusion on whether or not they currently have a nuclear warhead that can be delivered by missile,” said Gary Samore, who until early this year served as President Obama’s coordinator for weapons of mass destruction, “or how far away they are from getting there.”
Mr. Samore, now at Harvard’s Belfer Center, added that when it comes to arming the North’s Nodong missiles — which can hit South Korea and American troops there, but not beyond — with a nuclear warhead, “the best you can say is that they might have.”
A decade ago the Defense Intelligence Agency was among the most aggressive in pressing the case that Iraq had an active nuclear weapons program. It was famously deceived by information provided by an insider code-named “Curveball.”
But the differences between this case and Iraq are considerable. There is no argument that the North can build a modest bomb — its most recent test is believed to have yielded an explosion of 6 to 10 kilotons, less than what the United States dropped on Hiroshima. But there does not appear to be clear evidence of its work on miniaturizing that bomb.
An administration official said that including an unclassified passage in a largely classified seven-page assessment of North Korean capabilities by the Defense Intelligence Agency was “clearly a human error.” But he would not describe how it happened, nor would Defense Department officials say how that single conclusion ended up in the open, especially if it lacked the context of much more detailed reports.
In his statement, the famously press-shy Mr. Clapper said, “North Korea has not yet demonstrated the full range of capabilities necessary for a nuclear armed missile.”
On Friday morning, a Republican member of Congress said “demonstrated” was the crucial phrase: North Korea has never conducted a test of a warhead, showing that it could be precisely targeted or that it could survive the heat and forces of re-entry into the atmosphere. But he said that there is “a consensus building” among rival intelligence agencies that “If they are not there, they are close to there.” Differences among the assessments, he added, “are not huge.”
The last time the differences among intelligence agencies came into such sharp relief was 10 years ago this spring, when the Bush administration sought to explain why it had dismissed the dissenting opinions of parts of the intelligence community over Iraq’s nonconventional weapons.
The Defense Intelligence Agency’s conclusion was clearly an assessment that the Obama administration was not eager to share with the world. Officials said that at a moment when there were troubles with Iran and Syria, to say nothing of the rest of the Arab world, there was little desire to rekindle the North Korean crisis. That is especially true because North Korea has not demonstrated any capability to place its weapons on a missile, meaning that all the intelligence assessments were based on analysis, not discoveries.
But that effort came undone when a staff member on a House Armed Services subcommittee that oversees nuclear issues read a copy of the agency’s classified report, as part of his regular staff work, according to two people briefed on the matter who spoke on the condition of anonymity to describe the internal communications between Congress and the Pentagon.
The staff member noticed an important one-paragraph conclusion that was labeled “unclassified,” and went to the Defense Intelligence Agency’s legislative affairs liaison, who confirmed it. The staff member then alerted an influential member of the subcommittee, Representative Doug Lamborn, a fourth-term Republican of Colorado and a co-chairman of the House’s missile defense caucus, who decided to ask Defense Secretary Chuck Hagel and Gen. Martin E. Dempsey, the chairman of the Joint Chiefs of Staff, about the report’s conclusion at a budget hearing on Thursday. “It’s important to have all the facts on the table,” Mr. Lamborn said in a telephone interview Friday, adding that he had no misgivings about asking his question in a public hearing.
Republicans in Congress have led efforts to increase money for missile defense, and Mr. Lamborn said that he raised the issue largely because the Obama administration proposed this week in its annual budget submission to reduce financing for missile defenses by more than $500 million.
Given the agency’s responsibility for protecting American forces, it is not surprising that the Defense Intelligence Agency has been the most aggressive in arguing that North Korea is on the verge of marrying the products of its nuclear and missile programs. Two years ago, Lt. Gen. Ronald L. Burgess Jr., then the head of the agency, edged up to a similar conclusion, but with several caveats.
In testimony to Congress, he said, “The North may now have several plutonium-based nuclear warheads that it can deliver by ballistic missiles, and aircraft, as well as by unconventional means.” The last two in his list were important: it would require no new technology to devise a weapon to fit on a plane or a donkey cart.
The hardest task, experts say, would be for North Korea to design a warhead for an intercontinental missile. That warhead would go through the huge heat and stress of leaving, then re-entering the atmosphere. The North would have to design a warhead durable enough to keep from burning up, or breaking up, on re-entry. That is why other agencies are more skeptical.
