WASHINGTON After seven months of near-total secrecy, the White House is preparing to make public on Thursday video evidence of North Koreans working at a suspected Syrian nuclear reactor just before it was destroyed in an Israeli airstrike last September.
Until now, the administration has refused to discuss the video or the attack, other than in a highly classified briefing for a few allies and crucial members of Congress.
But senior officials in Israel and the United States have said the target was a nascent nuclear reactor that had been under construction for years. Israeli and American analysts had concluded that it was loosely modeled on the reactor North Korea used to obtain the fuel for its small nuclear weapons arsenal.
Israeli jets destroyed the site on Sept. 6, and the Syrians, after issuing some protests, bulldozed the area and constructed a building on the exact footprint of the old one. They have refused to allow international nuclear inspectors to visit the location.
The timing of the administration’s decision to declassify information about the Syrian project has raised widespread suspicions, especially in the State Department, that Vice President Dick Cheney and other administration hawks were hoping that releasing the information might undermine a potential deal with North Korea that would take it off an American list of state sponsors of terrorism.
“Making public the pictures is likely to inflame the North Koreans,” said one senior administration official who would not speak on the record because the White House and the State Department have declared there would be no public comment until the evidence is released. “And that’s just what opponents of this whole arrangement want, because they think the North Koreans will stalk off.”
But another senior official said it was possible that the revelations would force the North Koreans to describe their actions in Syria more fully when they issued a long delayed declaration of their nuclear activities.
That proposed deal, negotiated by Christopher R. Hill, the assistant secretary of state for East Asian and Pacific affairs and the primary interlocutor with North Korea, has become the latest battleground in a seven-year struggle within the Bush administration over North Korea policy.
That policy has veered from efforts to squeeze North Korea in hopes that the government of Kim Jong-il will collapse, to negotiating with the country alongside Russia, China, South Korea and Japan, each of which has pursued a somewhat different approach toward the North.
Mr. Hill was put in charge of the talks more than three years ago in the hope of finding a new way to deal with the North Koreans. But support for him has wavered, and President Bush has repeatedly warned aides not to agree to anything that “makes me look weak,” according to former officials who sat in on meetings with him on North Korea.
Mr. Cheney’s office and other conservatives have argued that Mr. Hill’s proposed deal would amount to a huge concession. In return for a minimal declaration from North Korea an accounting of how much plutonium it has produced it would be removed from the terrorism list and would no longer be subject to economic sanctions under the Trading With the Enemy Act.
North Korea has refused to say what, exactly, it provided to the Syrians, or what happened to an effort to start a second pathway to building arms, using uranium.
The deal would allow the North to continue to fudge on those matters, leaving unexplained the question of why it appeared to be buying uranium enrichment equipment from Pakistan. That equipment, many experts believe, was intended to help North Korea build a second path to a bomb, in case it was forced to give up its plutonium program.
In a presentation on Thursday to crucial members of Congress, and then in a presentation to reporters, American intelligence officials are expected to show images from a video, believed to have been obtained through Israeli intelligence services. The video, which Mr. Hill has shown to senior South Korean officials, shows Korean faces among the workers at the Syrian plant.
Other pictures, officials say, show what appears to be the construction of a reactor vessel inside the building that Israel later destroyed. It is unclear what the administration is willing to release. Syria’s ambassador to the United States, Imad Moustapha, did not answer messages left for him on Wednesday.
For weeks after the Israeli attack in September, neither Israeli nor American officials would talk about the attack, Israel’s first on a nuclear site since the 1981 attack on the Osirak nuclear reactor in Iraq.
When The New York Times published a lengthy account of the Syria attack on Oct. 14, revealing that Israeli and American analysts judged that the target was a partly constructed nuclear reactor, Mr. Bush and the White House refused to answer questions about it. Later, officials said they feared that the Syrians would retaliate against Israel if they felt publicly humiliated.
It is not clear what has changed, apart from the politics of the moment. Mr. Hill’s boss, Secretary of State Condoleezza Rice, has not voiced strong support for Mr. Hill’s effort to coax the North Koreans along, granting them rewards for steps along the way to compliance with a deal that calls, ultimately, for the country to give up its weapons.
Ms. Rice has been a strong critic of the 1994 agreement between North Korea and the Clinton administration, complaining that it was “front loaded” with rewards for the North.
That is exactly what critics say she and Mr. Hill have done in the most recent agreement. But Mr. Hill has argued in private that the Syrian episode and the uranium enrichment are side shows, and that the critical issue is stopping North Korea from producing more plutonium and giving up what it has. But his State Department colleagues say that he has been told not to defend the deal, or even explain it.
“He’s feeling pretty abandoned by Rice and Bush,” one of his colleagues said Wednesday. Mr. Hill did not respond to messages.
