Groups associated with al Qaeda are at the top of the list of threats to the United States, leading government intelligence officials said Wednesday, saying Iran has emerged as a top threat to American interests in the Middle East.
Despite gains made against al Qaeda, CIA Director Porter Goss, in an unusually blunt and chilling statement before the Senate Intelligence Committee, said the terror group is intent on finding ways to circumvent U.S. security enhancements to attack the homeland.
"It may be only a matter of time before al Qaeda or other groups attempt to use chemical, biological, radiological or nuclear weapons. We must focus on that," Goss said.
It was his first public testimony as CIA director, but Goss seemed to be holding back nothing from the usually secretive committee, CBS News National Security Correspondent David Martin reports.
The Senate Intelligence Committee's vice chairman Sen. Jay Rockefeller, D-W.Va., questioned Goss about recent reports about radioactive material missing from Russian nuclear sites that could, conceivably, be in the hands of terrorists.
"Is the material missing from Russian nuclear facilities sufficient to construct a nuclear weapon?" Rockefeller asked.
Goss replied: "There is sufficient material unaccounted for that it would be possible for those with know-how to construct a weapon."
And, as Martin reports, Goss could not assure the committee that the materials sufficient to make a nuclear weapon are not in the hands of terrorists.
"I can't account for some of the material so I can't make the assurance about its whereabouts," Goss told the committee.
FBI Director Robert Mueller said he worries about a true sleeper operative whom he contended has been in place for years to launch an attack inside the United States. "I remain very concerned about what we are not seeing," he said in his prepared remarks.
Mueller, Goss and other intelligence leaders provided these and other assessments at the annual briefing of threats from around the globe.
Also at the hearing, the head of the Defense Intelligence Agency, Vice Adm. Lowell Jacoby, painted Iran as a leading threat to U.S. interests in the Middle East. In his prepared testimony, Jacoby said he believes that Iran will continue its support for terrorism and aid for insurgents in Iraq.
He said the country's long-term goal is to expel the United States from the region, and noted that political reform movements there have lost momentum.
Goss said that Islamic extremists are exploiting the conflict in Iraq and fighters there represent a "potential pool of contacts" to build transnational terror groups. He said the most-wanted terrorist in Iraq, Abu Musab al-Zarqawi, hopes to establish Iraq as a safe-haven to bring about a final victory over the West.
Goss also said that the intelligence community has yet to get to the "end of the trail" of the nuclear black market run by disgraced Pakistani scientist, A.Q. Khan. He wouldn't rule out the possibility that organizations, rather than states, could obtain on nuclear, chemical or biological weapons. He called "potential Khans" a worry.
In the past year, the intelligence community has been faced with a series of negative reports, including the work of the Sept. 11 commission and the Senate Intelligence Committee's inquiry on the flawed Iraq intelligence.
President Bush's commission to investigate the intelligence community's capabilities on weapons of mass destruction is expected to release its findings next month.
Given the after-the-fact investigations into the Iraq intelligence, Senate Intelligence Chairman Pat Roberts, R-Kansas, said his panel will become more proactive in how it reviews the intelligence community's strengths and weaknesses, already focusing on nuclear terrorism and Iran.
In related developments:
"The extremists continue to plot to attack again. They are at this moment recalibrating and reorganizing. And so are we," the Pentagon chief said.
The hearing came as the White House continues its eight-week-long search for a new national intelligence director, a position created in last year's intelligence reorganization bill.
Democrats were critical Wednesday of the pace of the search, saying the administration has not shown the same urgency that Congress showed in creating the position.
"There should be another chair before us, with an accompanying name card that reads director of national intelligence," said Sen. Jay Rockefeller of West Virginia, the panel's ranking Democrat.
Roberts said it was "crucially important" to get the right person.
The hearing marked the first public appearance for Goss, the former House Intelligence Committee chairman, since his confirmation hearing in September.
Critics say he's politicizing the agency by surrounding himself with Republican advisers from his years in Congress. Yet his allies say he's promoting agency veterans to senior management positions and making changes essential to ensure the intelligence community does not repeat the kind of blunders that led up to the Sept. 11, 2001 terror attacks and the faulty prewar estimates of Iraq's weapons.
