The threat of accidental nuclear war

The threat of nuclear war puts enough stress on people that an

accidental nuclear war could be the result. With more and more of the

superpowers defences being controlled by complex computers, the chance

of a malfunction increases as well. Add this to normal human error and

governmental mistakes and you have a recipe for disaster. For this paper I

will be describing examples and systems of the United States, as Canada

has no nuclear weapons, and the USA's information is more readily

available than the other nuclear equipped countries.

"Accidental nuclear war" is a term for a very broad subject, with

hard to define boundaries. Technical errors, miscalculations and

unintended escalation can all lead to inadvertent nuclear war.

In the 1950's a flock of geese was mistaken for a squadron of

Russian bombers, and in 1960 a radar beam reflecting off the moon

duplicated a Soviet ICBM (Inter-Continental Ballistic Missile)(Barbara

Marsh, p.65). Both of these false alarms were detected in time to halt a

counter-strike mainly because it was peace time and no one's finger

poised over the "button". During a crisis, peoples high levels of stress

create suspicions where there shouldn't be, and as a result many safe

guards are removed that are in place to prevent an accidental launch. It is

feared that under these circumstances it would be quite easy for a flock of

geese to set off a nuclear war. Another fear is that a smaller nation, such

as recent Korea, could gain control of, and utilize nuclear weapons, and

trigger a war between the super powers. This type is called a catalytic

nuclear war.

There are two types of control over the operation of nuclear

weapons: positive and negative. Plans implemented in order to prevent

unauthorized use of the nuclear weapons - mechanical obstacles,

electronic locks, prohibitive operational procedures - are designated as

'negative controls'. An analogy for negative control could be a father

keeping his rifle unloaded, with the safety catch on and locked securely in

a gun cabinet so there is little chance that the rifle will be fired by

accident. Similarly there are numerous safeguards in place in order to

prevent the nuclear weapons from being fired accidentally.

Positive control means making sure that the nuclear missiles can be

launched quickly when the order to fire has been given. This involves the

reduction of negative control, and can be the cause for problems. An

analogy for positive control could be a father, knowing that there is an

intruder in the house, having his rifle loaded and ready to fire. Under both

exceptional pressure and apprehension, the rifle could easily be fired by

accident. So when all the safeguards are removed, all it takes is a few

moments of error to launch an accidental strike.

From 1977 to 1984 there were approximately eleven-hundred false

alarms but only six ever escalated to the point of a Threat Assessment

Conference (TAC), in which it is called a serious false alarm. There is the

possibility that a false alarm could take longer to confirm than the decision

time available, with the end result being the unintentional launch of

missiles. There is a model that can show the percent possibility of an

unresolved false alarm depending on decision time and duration of the

crisis. For example if the decision time is 15 minutes and it takes 2

minutes to resolve, during a crisis that goes on for 30 days, then the

percent possibility of accidental launching of ICBM's is about 0.2%. But

if decision time drops to only 6 minutes then the probability rises to over

50% (Wallace, Crissey, Sennot. pp.85-170 ).

Another threat related to accidental nuclear war is escaltiative

nuclear war, in which a minor situation becomes an all out nuclear war.

One scenario could be the escalation of a conventional war in Europe,

where the deployment of nuclear weapons along the front line would come

under the control of field commanders. Under these conditions the

"nuclear threshold" could easily be crossed if the field commanders were

pressed in any way(Fen Olser Hampson. pp.80-114).

A fully accidental war during a time of peace seems unlikely due to

the amount of negative controls in place to prevent accidental nuclear

weapons launch. But there are many people who want the USA to adopt a

'launch on warning system' but Barbara Marsh disagrees with this method

in her thesis on accidental nuclear war, stating that, by her calculation, an

accidental nuclear strike, under the current policy, which requires

warnings from both satellites and ground based radar, won't occur for

another 20,00 years. But under the 'launch on warning' system she

predicts that one will occur within the year. One way to lower the need for

a quick counter-strike or pre-emptive strike would be to increase the

survivability of the command centers. Allowing the government to ride

out the first strike and take as much time as necessary to consider a

response, with emphasis on survivability of forces and continuance of

strict negative control over all nuclear weapons (Bruce Blair.pp35-68).

The facts show that an accidental nuclear war is very unlikely to

occur during normal peace time conditions. The chance does increase

substantially during a crisis when positive control, the need to respond

quickly to attack, outweighs negative control. The major cause for an

accidental nuclear war will in all likelihood not be a malfunctioning

computer but a management problem, which will require substantial

looking in to and pending efforts in prevention. I believe that the two

super-powers have shown that they are responsible and have proven that

they really do mean to disarm, but the vacuum left by their nuclear

absence is being filled with many new faces, with problems of their own.
