The draft National Intelligence Estimate is expected to paint an ever-more-worrisome portrait of Al-Qaida's ability to use its base along the Pakistan-Afghan border to launch and inspire attacks, even as Bush administration officials say the U.S. is safer nearly six years into the war on terror.

 

Among the key findings of the classified estimate, which is still in draft form and must be approved by all 16 U.S. spy agencies:

 

Al-Qaida is probably still pursuing chemical, biological or nuclear weapons and would use them if its operatives developed sufficient capability.

 

The terror group has been able to restore three of the four key tools it would need to launch an attack on U.S. soil: a safe haven in Pakistan's tribal areas, operational lieutenants and senior leaders. It could not immediately be learned what the missing fourth element is.

 

The group will bolster its efforts to position operatives inside U.S. borders. In public statements, U.S. officials have expressed concern about the ease with which people can enter the United States through Europe because of a program that allows most Europeans to enter without visas.

 

The document also discusses increasing concern about individuals already inside the United States who are adopting an extremist brand of Islam.

 

National Intelligence Estimates are the most authoritative written judgments that reflect the consensus long-term thinking of senior intelligence analysts.

 

Government officials, who spoke on condition of anonymity because the report has not been finalized, described it as an expansive look at potential threats within the United States and said it required the cooperation of a number of national security agencies, including the CIA, FBI, Homeland Security Department and National Counterterrorism Center.

 

National security officials met at the White House on Thursday about the intelligence estimate and related counterterrorism issues. The tentative plan is to release a declassified version of the report and brief Congress on Tuesday, one government official said.

 

Ross Feinstein, spokesman for National Intelligence Director Mike McConnell, declined to discuss the document's specific contents. But he said it would be consistent with statements made by senior government officials at congressional hearings and elsewhere.

 

The estimate echoes the findings of another analysis prepared by the National Counterterrorism Center earlier this year and disclosed publicly on Wednesday.

 

That report  titled "Al-Qaida better positioned to strike the West" found the terrorist group is "considerably operationally stronger than a year ago" and has "regrouped to an extent not seen since 2001," a counterterrorism official familiar with the reports findings told The Associated Press.

 

On Thursday, news of the counterterrorism center's threat assessment renewed the political debate about the nature of the Al-Qaida threat and whether U.S. actions in Iraq in particular have made the U.S. safer from terrorism.

 

At a news conference Thursday, President Bush acknowledged Al-Qaida's continuing threat to the United States and used the new report as evidence his administration's policies are on the right course.

 

"The same folks that are bombing innocent people in Iraq were the ones who attacked us in America on Sept. 11," he said. "That's why what happens in Iraq matters to security here at home."

 

Yet Senate Intelligence Committee Chairman Jay Rockefeller, D-W.Va., said Iraq has distracted the United States. He said the U.S. should have finished off Al-Qaida in 2002 and 2003 along the Afghan-Pakistan border.

 

Instead, "President Bush chose to invade Iraq, thereby diverting our military and intelligence resources away from the real war on terrorism," Rockefeller said. "Threats to the United States homeland are not emanating from Iraq. They are coming from Al-Qaida leadership."

 

He called for the U.S. to end its involvement in what he called the Iraqi civil war.

In recent weeks, senior national security officials have been increasingly worried about an Al-Qaida attack in the United States.

 

Appearing on a half-dozen morning TV shows Thursday, Homeland Security Secretary Michael Chertoff laid out a list of factors contributing to his "gut feeling" that the nation faces a higher risk of attack this summer: Al-Qaida's increased freedom to train in South Asia, a flurry of public statements from the network's leadership, a history of summertime attacks, a broader range of attacks in North Africa and Europe, and homegrown terrorism increasing in Europe.

 

"Europe could become a platform for an attack against this country," Chertoff told CNN, although he and others continue to say they know of no specific, credible information pointing to an attack here.

 

National security officials are frustrated by an agreement last year between Pakistani President Gen. Pervez Musharraf and tribal leaders in western Pakistan, which gave tribes near the Afghan border greater autonomy and has led to increased Al-Qaida activity in the region.

 

Nevertheless, Bush administration officials still view Musharraf as a partner.

Speaking to a congressional hearing, Assistant Secretary of State Richard Boucher said that Pakistan under Musharraf has captured more al-Qaida operatives than any other country and that several major Taliban leaders were captured or killed this year.

 

"There is a considerable Al-Qaida presence at the border, but they are under pressure," Boucher told a House national security subcommittee.

 

Rep. Jim Cooper, D-Tenn., was skeptical, saying Osama bin-Laden and other terrorist leaders apparently feel safe there. "Is this a Motel 6 for terrorists?" he asked.
