In October 2002, President Bush made the case
for waging war against Iraq by raising
the specter of nuclear terrorism:
"If the Iraqi regime is able to produce, buy, or steal an amount of
highly enriched uranium a little larger than a single softball, it could have
a nuclear weapon in less than a year. And if we allow that to happen, a terrible
line would be crossed. Saddam Hussein would be in a position to blackmail anyone
who opposes his aggression. He would be in a position to dominate the Middle
East. He would be in a position to threaten America. And Saddam Hussein would
be in a position to pass nuclear technology to terrorists.
"Some citizens wonder, after 11 years of living with this problem,
why do we need to confront it now? And there's a reason. We've experienced the
horror of September the 11th. We have seen that those who hate America are willing
to crash airplanes into buildings full of innocent people. Our enemies would
be no less willing, in fact, they would be eager, to use biological or chemical,
or a nuclear weapon.
"Knowing these realities, America must not ignore the threat gathering
against us. Facing clear evidence of peril, we cannot wait for the final proof
– the smoking gun – that could come in the form of a mushroom cloud."
To put it charitably, President Bush clearly overstated the nuclear threat
posed by Iraq – not only did Saddam Hussein not have WMD or an active nuclear
weapons program, he had no history of supporting al-Qaeda or giving chemical
or biological weapons to the terrorist groups he did support. Yet the potential
threat of nuclear terrorism cannot be ignored. In 1998, when asked by ABC News
if he had acquired nuclear weapons, bin Laden replied, "I would state that
to acquire weapons in defense of Muslims is a religious duty." And according
to the former head of the CIA’s bin Laden Unit, Michael Scheuer, "We had
found that he and al-Qaeda were involved in an extraordinarily sophisticated
and professional effort to acquire weapons of mass destruction. In this case,
nuclear material, so by the end of 1996, it was clear that this was an organization
unlike any other one we had ever seen."
The question is: What is the appropriate response to this potential threat?
The Department of Homeland Security (DHS) created the Domestic Nuclear Detection
Office (DNDO) "to improve the Nation’s capability to detect and report
unauthorized attempts to import, possess, store, develop, or transport nuclear
or radiological material for use against the Nation." But trying to detect
a nuclear weapon to prevent a terrorist attack is a last ditch effort and amounts
to a needle-in-the-haystack operation because simply being able to detect the
presence of radiation (as one indicator of nuclear material) is not sufficient
(if the concern is a nuclear device rather than a radiological weapon such as
a dirty bomb). For example, there are legitimate commercial sources of industrial
and medical radiation that do not constitute a nuclear threat. Moreover, there
are many everyday sources of radiation, such as fertilizers, ceramics, bananas,
kitty litter, and smoke detectors.
The reality is that trying to play defense against a nuclear terrorist threat
is more than likely a losing proposition and that any success would probably
be the result of sheer luck. The problem of being able to detect nuclear materials
and the limits of current technology to do so is best illustrated by the fact
that twice (in September 2002 and September 2003) ABC News was able to smuggle
a 15-pound (6.8-kilogram) cylinder (about the size of a soda can) of depleted
uranium metal, loaned by Natural Resources Defense Council (NRDC), into the
United States – passing through U.S Customs in Staten Island, N.Y., in 2002
and Long Beach, Calif., in 2003.
What makes the ABC News stories particularly scary is the fact that the quantities
of weapons grade plutonium (WGPu) or highly enriched uranium (HEU) required
to build a nuclear weapon – and thus be detected – are relatively small. According
to the International Atomic Energy Agency (IAEA), a "significant quantity"
of WGPu to make a first generation nuclear bomb is 8 kilograms; a Natural Resources
Defense Council (NRDC) study concluded that only 1 kilogram of WGPu was needed
to build a nuclear fission weapon. According to the IAEA, a "significant
quantity" of HEU is 25 kilograms; the NRDC study concluded only 2 kilograms
of HEU was needed to build a nuclear fission weapon. This problem is further
compounded by the fact that potential sources of fissionable nuclear material
are widespread. According to the Nuclear Threat Initiative (NTI), in 2003 there
were over 50 tons (over 45,000 kilograms, or enough nuclear material to build
1,800 weapons) of HEU in civilian power and research programs in over 50 countries.
Therefore, one of the more important U.S. efforts is the Nunn-Lugar cooperative
threat reduction (CTR) program, which seeks to stop proliferation at its source
by assisting Russia and the former Soviet countries to destroy or secure nuclear
weapons and materials. The United States should consider conducting similar
efforts with other nuclear powers (Pakistan, India, and Israel), as well as
with potential future nuclear powers (North Korea, Iran) – all of which likely
share a common concern over nuclear safety and security, but may not have the
requisite experience, expertise, or technical capabilities. It may not be possible
to lock up nuclear weapons and materials to a Fort Knox "gold standard"
as proposed by Graham Allison, but every effort should be made to minimize the
possibility that existing nuclear stockpiles can be easily accessed or compromised
– especially since only relatively small quantities of weapons grade plutonium
or highly enriched uranium are needed to build a nuclear device. In the grand
scheme of things, the several hundred million dollars spent annually on CTR
is cheap insurance.
Cooperative threat reduction is important, but not a panacea. Ultimately, the
United States must engage in a foreign policy that reduces the motivations both
for proliferation and terrorism. Toward that end, U.S. policymakers must reexamine
their penchant for military interventionism as the default response. The President
Bush’s decision to invade Iraq is just one example, but the U.S. appetite for
military intervention predates the Bush administration. Since the end of the
Cold War marked by the opening of the Berlin Wall in 1989, the United States
has engaged in nine major military operations: Panama in 1989, the Persian Gulf
war in 1991, Somalia in 1992, Haiti in 1994, Bosnia in 1995, Iraq (Operation
Desert Fox) in 1998, Kosovo in 1999, Afghanistan in 2001, and Iraq in 2003 (if
enforcing the no-fly zones over Iraq is considered a military operation, then
the total is 10 and the possibility of military action against Iran is a looming
11th). It is also important to realize that President Clinton’s war in the Balkans
was essentially no different from the Bush administration's invasion of Iraq
to depose Saddam Hussein. Both were unnecessary military actions against sovereign
states conducted without the formal approval of the UN Security Council, neither
state represented an imminent threat to U.S. security, and both actions were
rationalized on humanitarian grounds.
The net result of unnecessary U.S. military interventionism is to create a
powerful reason for countries that are unable to match U.S. conventional military
power to acquire nuclear weapons as perhaps the only reliable deterrent against
U.S. military action. Moreover, U.S. interventionist policy is a strong source
of motivation for anti-American terrorism – including the 9/11 attacks. So making
noninterventionism the default policy would be a twofer.
Unfortunately, we cannot completely eliminate the risk of nuclear terrorism.
But changing U.S. foreign policy would go a long way toward dramatically reducing
it.
