U.S. Had Doubts on North Korean Uranium Drive
WASHINGTON, Feb. 28 — Last October, the North Koreans tested their first nuclear device, the fruition of decades of work to make a weapon out of plutonium.
For nearly five years, though, the Bush administration, based on intelligence estimates, has accused North Korea of also pursuing a secret, parallel path to a bomb, using enriched uranium. That accusation, first leveled in the fall of 2002, resulted in the rupture of an already tense relationship: The United States cut off oil supplies, and the North Koreans responded by throwing out international inspectors, building up their plutonium arsenal and, ultimately, producing that first plutonium bomb.
But now, American intelligence officials are publicly softening their position, admitting to doubts about how much progress the uranium enrichment program has actually made. The result has been new questions about the Bush administration’s decision to confront North Korea in 2002.
“The question now is whether we would be in the position of having to get the North Koreans to give up a sizable arsenal if this had been handled differently,” a senior administration official said this week.
The disclosure underscores broader questions about the ability of intelligence agencies to discern the precise status of foreign weapons programs. The original assessment about North Korea came during the same period that the administration was building its case about Iraq’s unconventional weapons programs, which turned out to be based on flawed intelligence. And the new North Korea assessment comes amid debate over intelligence about Iran’s weapons.
The public revelation of the intelligence agencies’ doubts, which have been brewing for some time, came almost by happenstance. In a little-noticed exchange on Tuesday at a hearing at the Senate Armed Services Committee, Joseph DeTrani, a longtime intelligence official, told Senator Jack Reed of Rhode Island that “we still have confidence that the program is in existence — at the mid-confidence level.” Under the intelligence agencies’ own definitions, that level “means the information is interpreted in various ways, we have alternative views” or it is not fully corroborated.
“The administration appears to have made a very costly decision that has resulted in a fourfold increase in the nuclear weapons of North Korea,” Senator Reed said in an interview on Wednesday. “If that was based in part on mixing up North Korea’s ambitions with their accomplishments, it’s important.”
Two administration officials, who declined to be identified, suggested that if the administration harbored the same doubts in 2002 that it harbored now, the negotiating strategy for dealing with North Korea might have been different — and the tit-for-tat actions that led to October’s nuclear test could, conceivably, have been avoided.
The strongest evidence for the original assessment was Pakistan’s sale to North Korea of upwards of 20 centrifuges, machines that spin fast to convert uranium gas into highly enriched uranium, a main fuel for atom bombs. Officials feared that the North Koreans would use those centrifuges as models to build a vast enrichment complex. But in interviews this week, experts inside and outside the government said that since then, little or no evidence of Korean procurements had emerged to back up those fears.
The continuing doubts prompted the Office of the Director of National Intelligence on Wednesday to declassify a portion of the most recent, one-page update circulated to top national security officials about the status of North Korea’s uranium program. The assessment, read by two senior intelligence officials, speaking on the condition of anonymity in a joint interview, said the intelligence community still had “high confidence that North Korea has pursued a uranium enrichment capability, which we assess is for a weapon.”
It added, they said, that all the government’s intelligence agencies “judge — most with moderate confidence — that this effort continues. The degree of progress towards producing enriched uranium remains unknown, however.”
In other words, while the agencies were certain of the initial purchases, confidence in the program’s overall existence appears to have dropped over the years — apparently from high to moderate.
