In August 1945 the US dropped atomic bombs at the Jap towns of Hiroshima and Nagasaki, killing greater than 200,000 other folks, overwhelmingly civilians. 80 years on from this slaughter – which the then US military commander and later president Dwight D. Eisenhower known as “completely unnecessary” – is an apt time to invite how the sector has modified since Japan’s skies lit up with atomic fireplace.
Many within the army in addition to teachers and nuclear theorists argue {that a} “third nuclear age” has begun. Via this they imply {that a} new and other set of nuclear threats are rising which essentially problem the prevailing tenets of nuclear “deterrence”. The reaction, some argue, is to take a position closely in our nuclear guns programs to safe ourselves in contrast new age of uncertainty.
To grasp this declare, it’s price taking a look again on the historical past of the nuclear technology. Maximum (however now not all) students operating on “nuclear ages” settle for that the primary nuclear age, between 1945 and 1991, used to be characterized by way of the chilly struggle nuclear stand-off between the sector’s two nuclear armed superpowers: the United States and the Soviet Union.
The second one nuclear age, from 1991 to 2014, is typically understood to have began when the chilly struggle ended. Policymakers nervous about “proliferation” – the unfold of nuclear guns to new states or even non-state terrorist teams. Western coverage curious about countering this procedure, incessantly via army method.
The 3rd nuclear age, which is believed to have begun in 2014, it concept to replicate a brand new set of demanding situations. This may increasingly contain the access of extra nuclear-armed states into the fray, erosion of longstanding non-proliferation and hands keep an eye on agreements and the advance of so-called “strategic non-nuclear weapons”. This time period refers to non-nuclear applied sciences, together with synthetic intelligence (AI) command and keep an eye on networks, hypersonic missiles and complex missile defence programs.
There are fears that non-nuclear armed “adversaries” may use those programs to immediately assault different states’ nuclear arsenals, undermining their skill to ship a retaliatory nuclear strike. That is more likely to pose a problem to established practices on which the doctrine of nuclear deterrence is primarily based.
However how a lot has in reality modified up to now decade? No new nuclear powers have emerged – the newest used to be North Korea in 2006. China, incessantly observed because the bogeyman of the 3rd nuclear age, has had a nuclear guns capacity since 1964. AI integration into nuclear command and keep an eye on programs, whilst extraordinarily dangerous, has but to occur.
Dependable missile defence in opposition to trendy nuclear warheads remains to be extensively regarded as to be technologically unattainable. The affect of hypersonic missiles at the calculus of nuclear deterrence is debated, since intercontinental ballistic missiles (ICBMs) are already very rapid.
Briefly, what’s other this time round?
Western-centric considering
A extra penetrating line of wondering is to invite in regards to the politics underlying the theory of a 3rd nuclear age. Concepts are by no means impartial, and so they form our figuring out of the sector. The 3rd nuclear age idea (like that of the second one nuclear age earlier than it) got here out of the United States defence established order, which used to be seeking to know how it would stay globally dominant in opposition to demanding situations to its supremacy from China.
The theory has since been filtered via academia and again into the coverage global, the place it has began to achieve “common sense status”: as night time follows day, the crack of dawn of the 3rd nuclear age is across the nook. However that is neither function nor inevitable. It’s a conceptual device for occupied with nuclear politics in a selected method.
It’s a US-centric viewpoint reflecting a terror that western dominance of the nuclear area is beneath risk. US and allied militaries wish to steadily combine new applied sciences into their nuclear programs and modernise their arsenals to care for a “more uncertain” global, ignoring the truth that large possibility and uncertainty have at all times been a integrated function of nuclear deterrence methods.
Right here, the largest threats to nuclear balance come now not from the hundreds of nuclear warheads held by way of the established nuclear guns states, however from would-be disruptors who can threaten nuclear arsenals with non-nuclear programs – echoing previous 2nd nuclear age fears about proliferation.
This is the reason Iran stays a villain of the tale along China, as we will be able to see from the hyperbole about Iran’s “hypersonic” missile features and the way its behaviour gave Israel and the United States the excuse to release “counter-proliferation” moves in opposition to its nuclear amenities in June this 12 months.

It bears repeating that Iran remains to be now not a nuclear-armed state. However the brand new emphasis put on non-nuclear applied sciences in 3rd nuclear age considering additionally places states which don’t also have nuclear programmes within the crosshairs of Iraq-style wars of aggression within the identify of “counter-proliferation”.
New hands race
To be crystal transparent: the nuclear global is as bad as ever. The issue is that 3rd nuclear age considering, with its center of attention on supposedly unparalleled disruptions, leads us to assume that new answers are essential. “Old” concepts about nuclear disarmament transform inappropriate, for the reason that instabilities offered by way of new applied sciences supposedly make it unattainable for nuclear guns states to surrender their arsenals.
The 3rd nuclear age turns into a conceptual stalking horse for a recent nuclear hands race.
When the British defense force leader Admiral Sir Tony Radakin warned of a dawning 3rd nuclear age in December 2024, he used to be now not creating a impartial commentary. He used to be arguing for assets to be funnelled into nuclear modernisation on the expense of welfare and healthcare programmes. As of late, earlier than any modernisation, Britain maintains a first-strike deliverable general of 31 megatons of nuclear explosive energy. That’s greater than 2,000 Hiroshimas’ price of destruction.
So we must be sceptical of this idea. The specter of nuclear annihilation has been with us since August 1945 and springs – as at all times – from nuclear guns and the states who function them.
