They undergo a process of nuclear fusion, forcing the nuclei of atoms together and multiplying exponentially the amount of energy released by the device. All strategic weapons in modern arsenals are now thermonuclear, or hydrogen, bombs. The bargain at the heart of the NPT was that member states without nuclear weapons agreed not to acquire them, as long as the states with weapons reduced their obscenely large arsenals, capable of destroying the planet many times over. That has indeed happened, to an extent — at first as the result of arms control agreements, and then the collapse of the Soviet bloc and the end of the cold war.
From a peak of 70, nuclear weapons in the world at the height of the cold war, in , there are now about 14,, according to the Federation of American Scientists FAS , still enough to end life on the planet. The rest are in reserve stockpiles or in the process of being retired and dismantled.
The last successful arms control agreement, the New Start treaty , was signed by Barack Obama and Dmitry Medvedev in , limiting the US and Russia to 1, deployed strategic warheads each. The hope at the time was that the two nuclear superpowers would pursue a follow-on treaty and at one point Obama suggested he might reduce the US arsenal unilaterally by another third.
But that did not happen.
The terrorist nuclear weapon is one of the scariest scenarios the world faces. Unlike states, such groups cannot be deterred from using a weapon as the perpetrator could be very hard to identify in the wake of a blast, difficult to find, and ready to accept death as the price of inflicting devastating damage. Terrorist groups would not need expensive missiles to deliver their warheads. They could be sailed into a port in a shipping container or across land borders in the back of a truck.
After the collapse of the Soviet Union, the US spent substantial resources on dismantling many of its weapons and production facilities as well as ensuring that its many nuclear scientists had alternative employment so as not to be tempted to sell their wares and expertise to the highest bidder. But serious concerns about nuclear weapons security remain. Pakistan in particular is a source of anxiety as its military and intelligence services have radicalised elements within them, with links to terror groups.
There are also fears that a cash-strapped or vengeful North Korea could sell one of its warheads for the right price. As the years have passed since the cold war, it has become increasingly clear that we had several lucky escapes from nuclear weapons use during that era as the result of miscalculation or technical glitches. For example, in , when a US watch officer left training tapes in the early warning system when he finished his shift, those in the incoming shift saw their screens light up with the tracks of multiple incoming Soviet missiles.
It was only good judgment of the duty officers that avoided a nuclear alert. Nearly three decades after the cold war, the US and Russia still keep hundreds of missiles on hair-trigger alert, ready to launch within minutes, in anticipation of just an occasion. In the US system, there is no institutional check or barrier to the president launching those missiles once he has identified himself to the Pentagon war room using his nuclear codes.
One option is that the two presidents could extend the New Start treaty by another five years, as allowed for in the agreement. It is more likely he would argue for a more ambitious arms control agreement he could put his own name to. But Putin will be hard to convince, without the US scaling back its missile defence system, and that is unlikely at the moment.
The threat of a conflict with North Korea has receded somewhat since the Singapore summit , but it is increasingly clear that Pyongyang has no intention of disarming any time soon. The big question is what will Trump do once that becomes apparent to him. The chances of a nuclear standoff with Iran , meanwhile, are rising.
In May, Trump walked out of the nuclear agreement with Tehran, which curbed Iranian nuclear activities in return for sanctions relief. The US is now piling on sanctions and telling the world to stop buying Iranian oil.
Sooner or later it is possible, likely even, that the Iranian government will stop abiding by the agreement and start stepping up its uranium enrichment and other activities. That is likely to raise tensions in the Gulf dramatically and make other regional players rethink whether to acquire nuclear weapons themselves. The darkest day of the cold war produced some timeless comedy, from the classic movie of accidental apocalypse, Dr Strangelove, to the songs of the mathematician, musician and comedian, Tom Lehrer, with titles like So Long Mom A song for WWIII , and in the UK, the civil defence sketch by Beyond the Fringe.
There are much darker works in the canon. On the Beach, in , was the first major post-apocalyptic movie, in which survivors gather in Australia, the last continent left habitable.
The Day After, in , is even blacker. It starts with a nuclear blast obliterating a column of cars stuck on a highway as panicked people rush to try to evade the attack spreads. More recent films, since the cold war, have dwelt on the threat of a single nuclear weapon detonated by terrorists or deranged geniuses or both. They include Broken Arrow , The Peacemaker and The Sum of All Fears , in which — because there is just one bomb involved — the detonation is no longer treated as an exctinction-level event.
Has any country ever given up its nuclear weapons? The bad news is we nuked the rest of the city to do it! This is not limited to image macros, it also applies to popular trends of any kind.

In that, art is following reality. The use of a nuclear weapon is now more likely than any time since the worst days of the cold war, but the probability of humanity being wiped out entirely by nuclear war is, for the time being, diminished.

The use of a nuclear weapon is now more likely than any time since the cold war, but the probability of humanity being wiped out entirely has diminished by Julian Borger and Ian Sample. Putin Trump Nuclear Weapons Photograph: And while the Nuclear Non-Proliferation Treaty has limited the new production of nuclear weapons, the world has experienced an uncurbed proliferation of conventional weapons with no effective international legal tools to control it. While some of it goes to infrastructure maintenance and salaries for personnel, a significant part is spent on the acquisition of conventional weapons.
According to the treaty, signatories should ensure the weapons they are selling are not going to be used in "terrorism", acts of genocide, crimes against humanity, serious violations of human rights, or the undermining of peace and security. Unfortunately, over the years since its signing, the treaty has proven too weak to make a difference. The second problem is that even if ATT signatories start implementing the commitments they made by signing the document, there are other countries that have either not signed or not ratified it, such as China , Russia, India and Iran.
The above point highlights the other difficulty with the ATT - namely, that it primarily deals with legal transfers. The problem is that many conflicts are now fuelled by weapons supplied via illegal trade, especially in small arms. This uncontrollable proliferation of conventional weapons will continue to take a heavy death toll each year unless the international community comes up with an effective international tool to control it - the way it did with nuclear weapons.
