How To Slash The Risks Of Nuclear War By 89%
Have you thought about nuclear war recently? Perhaps not, given the pandemic. But the danger hasn’t gone away. In fact, it’s never been higher.
So anything that will reduce the number of risks is welcome. Remarkably, the simple act of counting risks reveals how to slash their number by 89%.

Intro
After a nuclear war, we might never know the true cause. Chaos would reign. Tons of rubble would bury vital evidence.
But there would have to be a reason. A chain of events took place. A risk became a reality.
Those same risks live with us now. Like land mines in a field, they lie hidden and deadly.
Counting Risks
One way to reduce the risks of nuclear war is to cut the number of risks.
But first, we have to count them[1].
Nine countries in the world have nuclear weapons (nukes). But rather than dive in with all nine, we start with one country and build up.
One country
The USA became the first country to get nukes, in 1945.
One country means one risk:
- USA
This risk became reality in August 1945. The USA deliberately nuked and destroyed Hiroshima and Nagasaki.
Two countries
Russia became the second country to get nukes, in 1949.
With two countries we have:
- USA
- Russia
- USA—Russia
- Russia—USA.
There are 2 single-country risks, and 2 double-country risks. That’s 4 in total.
The last two risks look the same, at first sight. But the difference lies in who fires first[2].
Three countries
The UK became the third country to get nukes, in 1952.
There are now:
- 3 single-country risks,
- 6 double-country risks, and
- 6 triple-country risks[3].
That’s 15 risks in total.
Each risk has a different chance of happening. Triple-country risks are lower chance than double-country risks. It’s like dice – the chance of rolling three sixes is lower than the chance of rolling two sixes.
Four+ countries
Above four countries the risks skyrocket. Too many to count one by one.
So to reach our goal of nine countries with nukes, we need another approach. And a little maths and a pocket calculator comes to our rescue[4].
Here are the results:
Table 1 – Number of Risks of Nuclear War
Number of Countries with Nukes | Number of Risks |
---|---|
1 | 1 |
2 | 4 |
3 | 15 |
4 | 64 |
5 | 325 |
6 | 1,956 |
7 | 13,699 |
8 | 109,600 |
9 | 986,409 |
So today we live with nearly a million unseen risks of nuclear war.
Today’s Risks
A million risks of nuclear war is a huge number. So how has the world managed to escape up till now?
Fortunately, many risks have a very low chance.
But add up a million low chances, and one of them might happen. Since 1950 there have been almost seventy close calls[5]. That’s about one every year.
In short, it looks like we’ve been lucky so far.
But that’s hardly reassuring, is it?
Horror of Nuclear War
Things only need to go wrong once.
Any nuclear war brings suffering and death on a scale never seen before. Hiroshima and Nagasaki were terrible, yes, but today’s nukes are many times more powerful. And there are many more of them.
Even a ‘small’ nuclear war, say between India and Pakistan, would mean:
- Millions of tons of smoke block out the sun.
- Temperatures drop due to lack of sun, ushering in Nuclear winter.
- Global crops fail due to the freezing cold.
- Two billion people face starvation.
Relying on luck is reckless when the future of the planet is at stake.
But since we have no choice but to play the game, it makes sense to increase the odds in our favour.
How To Reduce Risks
Hidden in Table 1 is an astonishing fact.
Instead of reading the table from the top, start at the bottom and move up. See how risks shrink going from nine countries to eight? A shrinkage of 89% to be exact.
Figure 1 – Effect of one country disarming
I find this astonishing! Because if just one country disarms, 89% of the risks must disappear. Like a magic trick, hundreds of thousands of risks vanish into thin air!
Campaigners for unilateral disarmament were right all along[6].
Unfortunately, although the number of risks shrinks by 89%, the total chance does not. That’s because the risks that vanish have a very small chance of happening[7].
Even so, the chance of nuclear war does reduce. And if one country disarms, others may follow.
Summary
A single country disarming goes a long way to reduce the risks of nuclear war.
But it’s not the whole answer, of course. As long as any country has nukes, risks remain. That’s why all countries need to sign the new Nuclear Weapon Ban Treaty and disarm.
Still, an 89% cut to the number of risks is a great result.
One worth campaigning for.
