Sensors in Place to Detect Nuclear Threat
Alarmed by growing hints of al Qaeda's progress toward obtaining a nuclear or radiological weapon, the Bush administration has deployed hundreds of sophisticated sensors since November to U.S. borders, overseas facilities and choke points around Washington. It has placed the Delta Force, the nation's elite commando unit, on a new standby alert to seize control of nuclear materials that the sensors may detect.
...In "tabletop exercises" conducted as high as Cabinet level, President Bush's national security team has highlighted difficult choices the chief executive would face if the new sensors picked up a radiation signature on a boat steaming up the Potomac River or a truck heading for the capital on Interstate 95.
Participants in those exercises said the gaps in their knowledge are considerable. But the intelligence community, they said, believes that al Qaeda could already control a stolen Soviet-era tactical nuclear warhead or enough weapons-grade material to fashion a functioning, if less efficient, atomic bomb.
Even before more recent discoveries, some analysts regarded that prospect as substantial. Some expressed that view when the intelligence community devoted a full-day retreat to the subject early last year in Chantilly, Va., according to someone with firsthand knowledge.
...Bush's emphasis on nuclear terrorism dates from a briefing in the Situation Room during the last week of October.
According to knowledgeable sources, Director of Central Intelligence George J. Tenet walked the president through an accumulation of fresh evidence about al Qaeda's nuclear ambition. Described by one consumer of intelligence as "an incomplete mosaic" of fact, inference and potentially false leads, Tenet's briefing raised fears that "sent the president through the roof." With considerable emotion, two officials said, Bush ordered his national security team to give nuclear terrorism priority over every other threat to the United States.
Tenet told Bush that Pakistan's nuclear weapons program was more deeply compromised than either government has acknowledged publicly. Pakistan arrested two former nuclear scientists, Sultan Bashiruddin Mahmood and Abdul Majid, on Oct. 23, and interrogated them about contacts with bin Laden and his lieutenants.
Pakistani officials maintain that the scientists did not pass important secrets to al Qaeda, but they have not disclosed that Mahmood failed multiple polygraph examinations about his activities.
Most disturbing to U.S. intelligence was another leak from Pakistan's program that has not been mentioned in public. According to American sources, a third Pakistani nuclear scientist tried to negotiate the sale of an atomic weapon design to Libya. The Post was unable to learn which Pakistani blueprint was involved, whether the transaction was completed, or what became of the scientist after discovery. Pakistan's nuclear arsenal is believed to include bombs of relatively simple design, built around cores of highly enriched uranium, and more sophisticated weapons employing Chinese implosion technology to compress plutonium to a critical mass.
...A measure of the government's grave concern is the time devoted by top national security officials to developing options for a crisis involving nuclear terrorism.
One hypothetical scenario, participants said, began with a sensor detecting what appeared to be the radiation signature of a nuclear weapon amid a large volume of traffic on a highway such as I-95.
According to two participants, the group considered how the Energy Department's NEST teams, working with Delta Force, might find and take control of the weapon without giving a terrorist time to use it.
Roadblocks and car-by-car searches, for example, would create chaos, require hours, and give ample warning to those hiding the device. But without roadblocks the searchers might fail to isolate the weapon within a radius defined by the limits of sensor technology. If commandos found the device, they could expect to encounter resistance. Would the president delegate to on-scene commanders a decision that might result in nuclear detonation? Which officials, meanwhile, should be evacuated? Would government inform the public of the threat, a step that would wreak panic without precedent in any country and complicate the job of finding the weapon?
