WASHINGTON – The terrorist network al-Qaida will likely leverage its contacts and capabilities in Iraq to mount an attack on U.S. soil, according to a new National Intelligence Estimate on threats to the United States.

The declassified key findings, to be released publicly on Tuesday, were obtained in advance by The Associated Press.

The report lays out a range of dangers – from al-Qaida to Lebanese Hezbollah to non-Muslim radical groups – that pose a “persistent and evolving threat” to the country over the next three years. As expected, however, the findings focus most of their attention on the gravest terror problem: Osama bin Laden’s al-Qaida network.

The report makes clear that al-Qaida in Iraq, which has not yet posed a direct threat to U.S. soil, could become a problem here.

“Of note,” the analysts said, “we assess that al-Qaida will probably seek to leverage the contacts and capabilities of al-Qaida in Iraq (AQI), its most visible and capable affiliate and the only one known to have expressed a desire to attack the homeland.”

The analysts also found that al-Qaida’s association with its Iraqi affiliate helps the group to energize the broader Sunni Muslim extremist community, raise resources and recruit and indoctrinate operatives – “including for homeland attacks.”

National Intelligence Estimates are the most authoritative written judgments of the 16 spy agencies across the breadth of the U.S. government. These agencies reflect the consensus long-term thinking of top intelligence analysts.

The White House brushed off critics who allege the administration released the intelligence estimate at the same time the Senate is debating Iraq. White House press secretary Tony Snow pushed back at the critics Tuesday, saying they are “engaged in a little selective hearing themselves to shape the story in their own political ways.”

“We don’t keep it on the shelf and say ‘Let’s look for a convenient time,'” Snow said.

“We’re trying to remind people is that this is a real threat. This is not an attempt to divert. As a matter of fact … we would much rather – one of the things we’d like to do is call attention to the successes in the field” in Iraq, he said.

Democrats said the report was proof U.S. anti-terrorism efforts were being drained by the Iraq war.

“We must responsibly redeploy our troops out of Iraq, handing responsibility for security over to the Iraqis and leaving only those forces required for limited missions,” said Rep. Ike Skelton, D-Mo., chairman of the House Armed Services Committee. “This will allow us to concentrate our efforts on Afghanistan and the al-Qaida terrorists who attacked us on 9/11.”

House Republican leader Rep. John Boehner of Ohio said the report confirms gains made by Bush and blamed Democrats for being too soft on terrorism.

“Retreat is not a new way forward when the safety and security of future generations of Americans are at stake,” he said.

The new report echoed statements made by senior intelligence officials over the last year, including the assessment of spy agencies that the country is in a “heightened threat environment.” It also provided new details on their thinking and concerns.

For instance, the report says that worldwide counterterrorism efforts since 2001 have constrained al-Qaida’s ability to attack the U.S. again and convinced terror groups that U.S. soil is a tougher target.

But, the report quickly adds, analysts are concerned “that this level of international cooperation may wane as 9/11 becomes a more distant memory and perceptions of the threat diverge.”
