It could happen like this, in a fraction of a second:
Imagine hundreds of passengers enduring waves of heat outside Terminal
1 on a busy summer day at Los Angeles International Airport (LAX).
They stand in lines that weave down the sidewalk as a minivan
approaches the curb, then erupts in an explosion that rips through the
crowd and the terminal. An eerie cloud settles over the area.
Authorities arrive and determine that the vehicle-borne IED, or
improvised explosive device, was packed with cesium-137.
At the same moment, another bomb detonates in New York's Times Square.
This time, the device is filled with the radioactive substance
The material used in both "dirty bombs" was easily obtained. Cesium
helps to treat cancer. Americium is found in smoke detectors. What's
more, cesium causes cell damage. It reduces the ability to flex
muscles because of its chemical similarity to potassium. Americium
particles lodge in the bones. Long-term cancers may result.
Sadly, such a scenario is not just the stuff of Hollywood movies.
Designing a security strategy to prevent attacks like these is a huge
challenge, one which the next president may inherit. The Department of
Homeland Security (DHS) was expected to develop an effective strategy
against major threats. But six years after Sept. 11, ongoing,
high-profile failures do not inspire confidence. Border security
technology is full of bugs, and Katrina victims continue to suffer in
It is doubtful that the Bush administration will leave a comprehensive
strategy for homeland security. So, the next president will need to
provide one, which should include the following elements:
• Take the offensive against potential threats. Part of this equation
is better intelligence -- understanding the motivations and
capabilities of our enemies, and using that information to anticipate
and prevent attacks. For all its tough talk on terrorism, the Bush
administration has done a particularly poor job on this front.
• Secure dangerous materials. The ingredients for a dirty bomb can be
found in thousands of facilities across the United States -- from
hospitals to laboratories to water treatment plants -- which often have
extremely lax security.
Cesium and americium bind chemically to concrete and asphalt and
become lodged in cracks on the surface of sidewalks, streets and
buildings. Clean-up is nearly impossible. In some cases, demolition is
the only practical solution.
• Enhance international relationships and cultivate new ones. Our
allies are an extended defensive barrier, and there is much we can
learn. Our solid relationship with the British enabled us to disrupt a
terror plot to smuggle liquid explosives onto airplanes bound for the
United States in 2006.
• Make state and local law enforcement a truly integral part of a
homeland security strategy. Federal communication with these partners
must improve. Law enforcement stands on America's front lines and can
offer valuable perspectives that inform the national intelligence
cycle. They know their communities best. Programs established through
the recently enacted 9/11 act will help facilitate information-sharing
and avert needless panic caused by ambiguous "gut feelings." DHS's
continued unwillingness to include local first responders meaningfully
in preparing intelligence products borders on the irresponsible.
Threats to our nation will not cease anytime soon, and the next
president will not have the luxury of time to develop a strategy after
taking office. Passengers at LAX, tourists in Times Square and
Americans everywhere deserve one now.
