Now that President Bush has been reelected and
Franks-Bremer-Tenet awarded the Presidential Medal of Freedom, the Washington
Post has apparently decided to spill the beans about the true "weapons of
mass destruction" threat.
In particular, Dafna Linzer spilled
the beans about the nuke threat and John
Mintz about the chem-bio weapons threat. You ought to read Linzer-Mintz,
but you'll learn much more by reading the annual reports – beginning
in 1999 – of the Advisory Panel to Assess Domestic Response Capabilities
for Terrorism Involving Weapons of Mass Destruction.
Here are some relevant excerpts from the panel's first report.
"Many government officials and concerned citizens believe that 'it
is not a question of if, but when' an incident will occur that involves the
use by a terrorist of a chemical, biological, radiological, and nuclear (CBRN)
weapon – a so-called 'weapon of mass destruction' (WMD) – that is designed,
intended, or has the capability to cause 'mass destruction' or 'mass casualties.'
"[W]ith the exception of nuclear weapons, none of the unconventional
weapons by itself is, in fact, capable of wreaking mass destruction, at least
not in structural terms. Indeed, the terminology 'weapons of mass casualties'
may be a more accurate depiction of the potentially lethal power that could
be unleashed by chemical, biological, or non-explosive radiological weapons.
"The distinction is more than rhetorical and is critical to understanding
the vastly different levels of technological skills and capabilities, weapons
expertise, production requirements, and dissemination or delivery methods needed
to undertake an effective attack using either chemical or biological weapons
"The report explains, with some specificity, the challenges involved
in each of the four device or agent topic areas – biological, chemical, nuclear,
and radiological – which suggests that some public pronouncements and media
depictions about the ease with which terrorists might wreak genuine mass destruction
or inflict widespread casualties do not always reflect the significant hurdles
currently confronting any non-state entity seeking to employ such weapons.
"Although the collapse of the Soviet Union heightened Western fears
about security at Russian military facilities, it appears that Russian strategic
and tactical weapons are perhaps more secure than had been initially feared.
"But even if terrorists were able to steal or acquire through black-market
purchase a stolen nuclear weapon, they would still face a number of significant
obstacles in using or detonating it.
"Moreover, many tactical nuclear weapons, and most strategic nuclear
devices, are equipped with permissive action links (PALs) or other protective
mechanisms designed to prevent accidental or unauthorized detonation. In addition,
some nuclear devices have tamper-proof seals that will disable the weapon if
unauthorized personnel attempt to disassemble it.
"It would be extremely difficult, therefore, for terrorists to circumvent
or overcome these built-in protective measures.
"Building a nuclear device capable of producing mass destruction presents
Herculean challenges for terrorists and indeed even for states with well-funded
and sophisticated programs. According to one analysis, minimum requirements
include 'personnel, skills, information, money, facilities, equipment, supplies,
security, special nuclear materials ... and, usually, other specialized and
"That being said, it is clear that certain types of nuclear devices
are easier to create than others.
"Two types of weapons systems, for example, can create nuclear fission:
the implosion device and the 'gun' type. In the former, explosives compress
a sphere of HEU or plutonium into a small ball, thus achieving supercriticality
and a nuclear chain reaction.
"Even the simplest implosion weapon, however, requires the fabrication
of complex components, such as high-explosive lenses, high-performance detonation
systems, and fusing and firing circuitry.
"The gun-type device, on the other hand, employs HEU exclusively. Using
a high explosive, the system fires a subcritical HEU projectile into a subcritical
cylinder of HEU to form a solid mass of critical material. Although it uses
relatively scarce HEU, the gun-type device is considered technically easier
to fabricate; and many analysts accordingly argue that terrorists attempting
to make a bomb 'in house' will build a gun-type device."
Note that the panel focused – as does the Department of Homeland Security –
on domestic response to terrorist acts, not on preventing them.
That's just as well, since it will be virtually impossible to prevent
all, or even most, high-probability low-consequence acts.
However, it would have been possible to prevent a terrorist nuke attack. But
then Bush accused Iraq, Iran, and North Korea of developing nukes to give to
terrorists for use against us. Bush launched a "preemptive" strike against Iraq
and is currently threatening similar strikes against Iran and North Korea.
Result? Stay tuned.
