The Nuclear Risk: How Long Will Our Luck Hold?

The Nuclear Risk: How Long Will Our Luck Hold?

This is how a submarine-launched ballistic missile works: once airborne, the
60-ton missile travels out of the earth’s atmosphere into sub-orbit, where
it moves toward its target at a shade under 4 miles a second.
Approaching its destination, the tip of the missile splits into multiple,
independently targeted warheads, each loaded with bombs up to 24
times more powerful than the Hiroshima blast, which re-enter the atmosphere
in a spectacle that from the ground would resemble a meteor shower, before
it resembled a thousand roaring suns.

There are hundreds of these and similar land-based long-range missiles ready
to launch at a moment’s notice. Only the original nuclear club countries
have them — America, Russia, China, Britain and France. Those who justify the
continued existence of these giant arsenals argue that the stability
provided by such “deterrents” far outweigh the risk. The launch of one or
all of these missiles — whether by design or by accident — would be a highly
improbable event.

But not an impossible one. Sometime on Feb. 3 or 4, a British nuclear
submarine carrying an estimated 50 nuclear warheads crashed into a French
nuclear submarine with a similar payload in the depths of the Atlantic. When
the event was leaked to a British newspaper on Feb. 16, both governments
were quick to point out that there was no risk to the missiles on board.
French defense minister Herve Morin called the collision an “incredible
incident,” and promised better communication with the British. Some
commentators estimated the chance of two submarines intersecting in such a
vast body of water at one in 85 million.

But to marvel at the bizarre coincidence of the collision, or to breathe a
sigh of relief that nuclear safety was not breached, is to miss the point.
The seemingly impossible collision of two subs in a large ocean should
remind us of the fallacy by which we assume nuclear weapons will never be
used. Because the threat of global nuclear war is not zero, even a small
chance of war each year, multiplied over a number of years, adds up to the
likelihood that the weapons will be used. Like those two subs
stalking through the Atlantic, the odds will begin to align. Mathematically,
they are destined to.

This is not a mere logic game. If there is a single “big idea” to have emerged in the first decade of the
new millennium — from the September 11 attacks to the financial crash — it is
the notion of the “black swan,” the
danger posed by difficult to predict, high-impact events. The short history
of nuclear weapons is already scattered with unplanned and seemingly
improbable incidents that suggest we feel more secure than we should. In
1995, a communication failure with the Russian Embassy led the Russian
military to believe that a weather rocket launched off the coast of Norway
was an incoming submarine-launched ballistic missile. In the 1980s,
malfunctioning U.S. missile defense systems relayed information to U.S.
officials of a massive incoming first strike — twice. As recently as 2007, a
U.S. Air Force plane flew across the American heartland while unknowingly
carrying several live warheads on board. At the time, all of these events
were described as freak occurrences. The truth is they were freak
occurrences. But they happened.

A day after the latest nuclear accident became public, an analyst from the
Federation of American Scientists, a nonproliferation think tank, released
U.S. Naval intelligence documents obtained through the Freedom of
Information Act that showed that the Russian Navy undertook more underwater
ballistic missile submarine patrols in 2008 than it has in a decade. The
Russian subs are joined in the word’s oceans by nuclear-armed vessels from
France, Britain, and China. Under the plains of the American West, and in
similar silos in Russia, Air Force missile operators keep constant vigil,
launch keys at the ready. Nuclear missiles have no self-destruct button;
once launched, they cannot be called back. Twenty years after the end of the
cold war, humanity still lives within 30 minutes of its own destruction. The
price we pay for maintaining nuclear weapons is the gamble that the highly
improbable will not lead to the unthinkable. The question to ask after this
latest nervy episode: is it worth it
