The top official at the U.S. Department of Homeland Security is concerned about the possibility of an attack in the United States involving weapons of mass destruction. A day after the fifth anniversary of the September 11, 2001 terrorist attacks on the United States, Secretary Michael Chertoff testified about future threats to the homeland before a Senate committee.
He told the Senate Homeland Security and Governmental Affairs Committee that the gravest threat facing the United States is one involving weapons of mass destruction.
"A nuclear bomb is at the end of the scale, a biological attack, even a serious radiological attack, would have very, very powerful effects on the entire country. The good news is that a nuclear bomb, the likelihood of that happening, the threat in terms of capability is low at this point. On the other hand, I have no reason to believe that that threat is going to diminish over time, and I do have reason to believe it is going to increase over time," he said.
Chertoff says the federal government is taking steps to prevent such a scenario by improving intelligence and establishing radiation detection systems.
He says by the end of next year, all cargo containers coming from foreign ports will be screened by radiation monitors once they arrive at U.S. ports.
Chertoff says the United States is also working with foreign governments to have cargo scanned before it is loaded onto U.S.- bound ships - an effort that he acknowledges may not be immediately embraced by many countries.
"When containers go through the system that we are proposing to start to deploy, when they "hit" a red light, the container has to be pulled out and you have to inspect it. The authority to do that lies with foreign governments. We work with them, but it is their authority that we use to open the containers. They rightly worry about the burden on their own customs officials in terms of whether they have the manpower and the capacity to do that," he said.
As Chertoff testified, U.S. Treasury officials were briefing another Senate committee about progress made in cracking down on the flow of money to terrorist groups.
Daniel Glaser is the Treasury Department's deputy assistant secretary for terrorist financing and financial crimes. "We have elevated the costs, risks and difficulties for terrorists to raise and move funds in support of their operations," he said.
But Glaser acknowledged more needs to be done.
The committee's chairman, Senator Richard Shelby, an Alabama Republican, agreed, saying terrorists have shown the ability to adapt. "Charities closed by governments have resurfaced under new names. Exploitation of formula banking systems have been replaced by the increasing use of bulk cash couriers. And of particular concern to this committee, the use of shell and front companies continue to constitute a serious weakness in even our own anti-money laundering and terror finance regulatory regimes," he said.
In its latest action Friday, the Treasury Department barred Iran's state-run Bank Saderat from having any links with U.S.-owned banks, citing what it called the bank's support for terrorism.
