Why Would an Atomic Bomb Be Used Again
The shockwave and rut that the detonation of a single nuclear weapon creates can end the lives of millions of people immediately.
Only even larger is the destruction that would follow a nuclear war.
The showtime reason for this is nuclear fallout. Radioactive dust from the detonating bombs rises up into the atmosphere and spreads out over large areas of the earth from where it falls downward and causes mortiferous levels of radiation.
The second reason is less widely known. Simply this consequence – 'nuclear winter' and the worldwide famine that would follow – is now believed to exist the nigh serious outcome of nuclear war.
Cities that are attacked by nuclear missiles fire at such an intensity that they create their own wind system, a firestorm: hot air above the burning urban center ascends and is replaced by air that rushes in from all directions. The storm-force winds fan the flames and create immense heat.
From this firestorm large columns of smoke and soot ascension upward above the burning cities and travel all the way upward to the stratosphere. There it spreads effectually the planet and blocks the sun's light. At that swell height – far above the clouds – information technology cannot exist rained out, meaning that it will remain there for years, concealment the sky and thereby drying and chilling the planet.
The nuclear winter that would follow a big-scale nuclear war is expected to lead to temperature declines of xx or fifty-fifty 30 degrees Celsius (60–86° F) in many of the world'south agricultural regions – including much of Eurasia and North America. Nuclear wintertime would cause a 'nuclear famine'. The world's nutrient product would neglect and billions of people would starve.1
These consequences – nuclear fallout and nuclear winter leading to famine – hateful that the destruction caused by nuclear weapons is non independent to the battlefield. It would not merely harm the attacked country. Nuclear war would devastate all countries, including the attacker.
The possibility of global devastation is what makes the prospect of nuclear war so very terrifying. And it is also why nuclear weapons are so unattractive for warfare. A weapon that can lead to self-destruction is non a weapon that tin can be used strategically.
United states President Reagan put it in clear words at the height of the Common cold War: "A nuclear war cannot be won and must never be fought. The only value in our ii nations possessing nuclear weapons is to make sure they will never be used. But then would it not exist meliorate to do away with them entirely?" 2
Nuclear stockpiles have been reduced, but the risk remains high
40 years after Reagan'due south words, the Cold War is over and nuclear stockpiles have been reduced considerably, equally the chart shows.
The world has learned that nuclear armament is not the i-mode street that it was one time believed to exist. Disarmament is possible.
But the chart besides shows that there are nevertheless nigh ten thousand nuclear weapons distributed among nine countries on our planet, at least.3 Each of these weapons tin cause enormous destruction; many are much larger than the ones that the The states dropped on Hiroshima and Nagasaki.4
Collectively these weapons are immensely subversive. The nuclear winter scenario outlined above would impale billions of people—billions—in the years that follow a large-scale nuclear war, even if it was fought "but" with today'south reduced stockpiles.5
It is unclear whether humanity as a species could possibly survive a total-scale nuclear war with the current stockpiles.6 A nuclear war might well be humanity's final state of war.
Close Calls: Instances that threatened to button the 'balance of terror' out of residual and into war
The 'residual of terror' is the idea that all involved political leaders are so scared of nuclear war that they never launch a nuclear attack.
If this is achievable at all, it tin can only be accomplished if all nuclear powers keep their weapons in cheque. This is because the balance is vulnerable to accidents: a nuclear flop that detonates accidentally – or even just a false alarm, with no weapons even involved – can trigger nuclear retaliation considering several countries continue their nuclear weapons on 'launch on warning'; in response to a warning, their leaders can decide within minutes whether they want to launch a retaliatory strike.
For the rest of terror to be a rest, all parties need to be in control at all times. This however is non the instance.
In the timeline, you can read through some of the close calls during the past decades.
The risk of nuclear war might well be low – because neither side would want to fight such a state of war that would have such awful consequences for everyone on the planet. But in that location is a hazard that the kinds of technical errors and accidents listed here could lead accidentally to the use of nuclear weapons, every bit a nuclear power tin can incorrectly come to believe that they are nether attack.
This is why simulated alarms, errors, and shut calls are so crucial to monitor: they are the incidents that tin can push the 'balance of terror' out of balance and into state of war.
Accidents and errors are of form not the simply possible path that could lead to the apply of nuclear weapons. There is the chance of a terribly irresponsible person leading a country possessing nuclear weapons. There is the risk of nuclear terrorism, possibly subsequently a terrorist organization steals weapons. At that place is the possibility that hackers tin can take command of the nuclear chain of command. And at that place is the possibility that several of these factors play a function at the aforementioned time.
A timeline of nuclear weapons 'close calls' 7
Below this post, you observe additional lists of close calls, where yous find much more information on each of these incidents.
How to reduce the risk of nuclear war?
An escalating conflict between nuclear powers – just also an accident, a hacker, a terrorist, or an irresponsible leader – could lead to the detonation of nuclear weapons.
Those risks only go to zip if all nuclear weapons are removed from the world. I believe this is what humanity should work towards, just information technology is exceedingly hard to attain, at least in the short term. Information technology is therefore important to see that there are boosted ways that tin reduce the adventure of the globe suffering the horrors of nuclear war.8
A more peaceful world: Many world regions in which our ancestors fought merciless wars over endless generations are extraordinarily peaceful in our times. The ascent of democracy, international merchandise, diplomacy, and a cultural attitude shift against the glorification of war are some of the drivers credited for this development.9
Making the globe a more peaceful place will reduce the take chances of nuclear confrontation. Efforts that reduce the chance of whatsoever state of war reduce the chance of nuclear war.
Nuclear treaties: Several non-proliferation treaties have been primal in achieving the large reduction of nuclear stockpiles. Withal, fundamental treaties – like the Intermediate-Range Nuclear Forces (INF) Treaty between the United states of america and Russia – take been suspended and additional agreements could be reached.
The Un Treaty on the Prohibition of Nuclear Weapons, which became constructive in 2021, is a contempo development in this direction.
Smaller nuclear stockpiles: Reducing the stockpiles further is seen as an important and achievable goal past experts.
It is considered achievable because smaller stockpiles would still provide the deterrence benefits from nuclear weapons. And information technology is important as information technology reduces the risk of accidents and the hazard that a possible nuclear war would end civilization.
Better monitoring, meliorate control: The risk tin be further reduced by efforts to better control nuclear weapons – so that close calls occur less frequently. Similarly improve monitoring systems would reduce the hazard of false alarms.
Taking nuclear weapons off 'pilus-trigger alarm' would reduce the risk that any accident that does occur can rapidly spiral out of control. And a well-resourced International Atomic Energy Agency can verify that the agreements in the treaties are met.
Meliorate public understanding, global relations, and civilisation: Finally I also believe that it will help to see clearly that billions of us share the same goal. None of us wants to live through a nuclear war, none of united states wants to die in one. Every bit Reagan said, a nuclear state of war cannot exist won and it would be better to practise away with these weapons entirely.
A generation ago a wide and highly visible societal motility pursued the goal of nuclear disarmament. These efforts were to a expert extent successful. Merely since then, this goal has unfortunately lost much of the attention information technology in one case received – and this is despite the fact that things have not fundamentally inverse: the world still possesses weapons that could kill billions.x I wish information technology was a more prominent concern in our generation then that more young people would set themselves the goal to make the world safe from nuclear weapons.

Conclusion
I believe some dangers are exaggerated – for example, I believe that the fearfulness of terrorist attacks is oftentimes wildly out of proportion with the actual take chances. But when it comes to nuclear weapons I believe the contrary is truthful.
At that place are many today who inappreciably give nuclear conflict a thought and I think this is a large mistake.
For eight decades people have been producing nuclear weapons. Several countries have dedicated vast sums of money to their construction. And now we live in a world in which these weapons endanger our unabridged civilization and our future.
These subversive weapons are possibly the clearest instance that applied science and innovation are non but forces for good, they can also enable catastrophic destruction.
Without the 2d World State of war and the Cold War, the world might have never adult these weapons and we might discover the idea that anyone could possibly build such weapons unimaginable. Simply this is not the world we live in. Nosotros live in a world with weapons of enormous destructiveness and nosotros accept to see the risks that they pose to all of united states and find ways to reduce them.
I promise that there are many in the globe today who take on the challenge to make the world more peaceful and to reduce the risk from nuclear weapons. The goal has to be that humanity never ends up using this most destructive technology that we ever adult.
