Homeland Security In 1945, the United States put a final and definitive end to World War II when it used two atomic bombs on Japan, forcing their surrender. At that time the entire world learned of the terrible potential of weapons of mass destruction. Unfortunately, as the major nations have backed away from weapons of mass destruction (WWD), terrorist organizations have sought to acquire them. Worse, technological advances have made it possible for to be constructed on a small enough scale that they could feasibly be smuggled anywhere in the world.

We have seen isolated use of such weapons. Terrorists released the nerve gas Sarin into a Tokyo subway some years ago, anthrax was used in the United States with the Postal Service as the delivery method, and al-Qaeda killed thousands in 2001 by flying fuel-laden passenger planes into buildings (Quillen, 2002). The last event in particular demonstrated that some groups want to leave a large mark from their terrorist activities, making the threat of WWD in their hands a real threat.

One of the greatest concerns of those charged with protecting us from terrorist attacks is that of nuclear and radiological devices. The word "nuclear" immediately puts fear in people because what we know of nuclear weapons is the kind of wide-scale obliteration that occurred in Nagasaki and Hiroshima at the end of World War II. However, there are two kinds of nuclear weapons terrorists might use. One threat is more realistic than the other.

Nuclear weapons are strategic armaments built by countries for offensive and defensive purposes. They are relatively difficult to build and to use, and most countries keep careful track of them, making them hard for terrorists organizations to acquire and hard for them to use. A second kind of nuclear device has been called a "dirty bomb," but can also be called a "radiological dispersion device," or RDD. One of the biggest risk factors...

They can be set of with more conventional explosives such as dynamite (Litman, 2003). While they would not have tremendous destructive power, they could contaminate areas with radioactivity. Their capacity for inflicting terror as well as radiation sickness in a small area makes them of great concern to governments.
Major political changes in some countries over the past 15 years add to the concerns. With the breakup of the U.S.S.R., the resulting independent states have shown some lack of ability to track their nuclear materials. Individuals have seen opportunities to sell nuclear materials on the black market. It is quite possible that weapons as well as the raw materials to make atomic and RDD weapons have been surreptitiously sold. It is likely that some have been sold to both countries and organizations antagonistic to the United States.

Among the countries that used to make up the U.S.S.R., for instance, up to 650 tons of nuclear material is stored in scattered locations. Experts estimate that it would take only 8 kilograms of plutonium and 15 -- 25 kilograms of enriched uranium to make a nuclear bomb capable of inflicting great damage (Lee, 2003). However, This is still al large amount of material. Transporting such a bomb as well as detonating it would be problematic for a small organization. The real risk from terrorists are dirty bombs, which would do less physical damage but have serious environmental effects in the area near where it was detonated.

So the question becomes, who is likely to use such weapons. It used to be believed that terrorist organizations were left-wing oriented, concerned with the issues of exploitation and oppression of groups of people. Believing that, nations concerned with fighting terrorism tended to believe that if the social…
