Keep in mind those reports are OS. While some Classified information makes it into the higher level reports and is then scrubbed,
No Special Access Programs or Intelligence makes it into them.
So there can be multiple ‘truths’ depending on what one has access to.
Here is the National Intelligence Estimate reporting process. Excerpted from a 2008 article attached below.
"The NIE process from inception to completion progresses as follows:
A senior executive branch official, a committee chair of the House or Senate, or a senior military official can request an NIE. An estimate can also be initiated independently by the National Intelligence Council. The request is authorized by the Director of National Intelligence.
The NIC prepares the terms of reference, an outline of the key issues, and questions to be covered in the estimate.
Before an NIE is drafted the intelligence officer produces a terms of reference paper, or TOR, meant to define the key questions the NIE is to address; sets drafting responsibilities; and establishes a publication schedule. The TOR is circulated throughout the intelligence community for comment.
The intelligence officer selects a lead drafter of the NIE or directs another intelligence analyst or outside expert to do so. The draft is typically reviewed by the NIC before it is sent to the U.S. government agencies that are members of the intelligence community, or compile national intelligence on the relevant issue.
Agency experts review the draft and prepare comments.
Agency representatives meet and discuss the report at an interagency coordination session.
Intelligence is vetted by the National Clandestine Service within the Central Intelligence Agency (CIA) to eliminate potentially questionable or unreliable sources.
A final draft is distributed for final review to intelligence community experts for their review. In addition, the NIE often includes a summary of the opinions of experts outside the government.
The NIC reviews the final draft and then forwards it to the National Intelligence Board (PDF). The board is composed of senior representatives of the intelligence community and is chaired by the DNI.
Once an NIE is approved by the National Intelligence Board it is delivered to the requester as well as the president, senior policymakers, and relevant members of Congress.
Up to seventeen agencies and departments are generally involved in the process."
Note that it has since grown to 18 departments and agencies. The belief that a DNI report does not use intelligence is incorrect. The National Clandestine Service scrubs it for sources and methods, or just general bullshit that ended up in it, for the very reason that it is derived from various types of intelligence sources.
Of particular note, and the reason I chose this article for my response,
If they aren't working on a bomb, why their focus on enrichment? What possible alternative use could it serve and why spend the money burying it beneath a mountain if it is for civilian/commercial use only.
this question is addressed directly at the end of the article.
"Changes to the NIE process are most evident in the community’s estimate on Iranian nuclear capabilities. The classified estimate is said to be roughly 140 pages long and includes extensive sourcing footnotes and alternative hypotheses. In terms of tradecraft the Iran nuclear NIE is said to be the most rigorous ever produced. Among the estimate’s conclusions are judgments that Tehran continues to enrich uranium for declared civilian use; and that it is keeping its options for restarting its weapons program open. But the finding that generated the most attention was the intelligence community’s “high confidence” that Iran had halted its nuclear weapons program in fall 2003."
