Each time Vladimir Putin raises the spectre of nuclear confrontation, the trail ultimately leads back to one man.

Eighty years before the Russian president invaded Ukraine, and brought the potential of such weapons back to mainstream attention, J Robert Oppenheimer was recruited to lead a team that would construct the world’s first atomic bombs.

Ukraine war – follow the latest developments

The Manhattan Project, set up during the Second World War in 1942, was guided by fear that if the US and its allies didn’t make them first, Hitler’s Nazi scientists would.

A left-wing theoretical physicist not known for his leadership qualities or laboratory acumen, the American was an unconventional pick but proved a devastatingly effective one.

As blockbuster biopic Oppenheimer hits cinemas, Sky News looks at how the father of the atomic bomb still shapes the world decades after his creation was deployed.

Oppenheimer film ‘puts audience in bunker’

An unusual recruitment

Oppenheimer was appointed by General Leslie Groves, the project’s military leader, to head up Site Y – a secret weapons research facility at Los Alamos, New Mexico.

But there were, as Oppenheimer biographer Professor Ray Monk puts it, “all sorts of reasons” not to appoint him, notably perceived association with communist organisations that had made him a suspect of the FBI.

Born to a Jewish family in New York in 1906, his student years had seen him drawn to the left as Germany’s fascist regime saw friends and relatives oppressed and forced to flee.

During studies at Harvard, Cambridge, and Germany‘s Gottingen university in the 1920s, he was known for being a “disaster in the laboratory”. Of his time studying physics at Harvard, Oppenheimer himself said: “My feeling about myself was always one of extreme discontent.”

He may have been unconvincing in the lab, but found his calling as a university lecturer in California. His ability to explain complex science in a relatively straightforward and compelling way proved key to impressing Groves, who interviewed countless scientists before a chance meeting with Oppenheimer.

Crucially, he also recognised the need for urgency.

Prof Monk says: “Oppenheimer knew Heisenberg, one of the greatest scientists in the world, who he worked with at Gottingen, was leading the Nazi bomb project and was worried they would get one before the Allies.

“He was in no doubt at all – the duty of all scientists in the US, and the allied countries, was building a bomb first.”

Building the bomb

Los Alamos was one of three sites critical to the development of the atomic bomb.

The others were a factory in Hanford, Washington, where plutonium was made; and a hidden base in Oak Ridge, Tennessee, for enriching uranium.

The two elements would act as fuel for the bombs made at Los Alamos, two of which would be dropped on the Japanese cities of Nagasaki and Hiroshima in August 1945.

THE SCIENCE BEHIND OPPENHEIMER’S BOMB

The basis of the atomic bomb is the process of nuclear fission – when the nucleus of an atom is split into two smaller nuclei, releasing a large amount of energy in the process.

This was discovered in 1938 by two German scientists, and Oppenheimer realised its destructive potential when word reached him in 1939.

The prospect of weaponising nuclear fission focused the minds of scientists across Europe, with plutonium and uranium identified as elements that could undergo the process.

With the process understood, the race was on to weaponise it.

Cynthia C Kelly is founder and president of the Atomic Heritage Foundation, dedicated to the preservation of the Manhattan Project and crucial to having the three sites gain national park status in the US.

“It was a first-of-a-kind effort across the board,” she says of the Manhattan Project, named after the New York City district where it was founded.

With the city that never sleeps deemed too busy for such a secretive initiative, the three laboratories were set up in isolated places far away from urban centres and the coast. They brought together geniuses from across America and overseas – including Britain and some who fled Nazi Germany – into one single-minded pursuit.

“It required creative minds from the machinists to the craftsmen – everything had to be perfect,” Kelly adds, with a “classic absent-minded professor” at the heart of it.

“They had to take this energy, which had been uncontrolled up to now, figure out how to control it, and package it tightly enough to fit in the bomb bay of an aeroplane that could transport it and drop it.

“They had little confidence in harnessing this technology in time for the end of the war.”

Becoming Death

But harness it they did – and the world would change forever.

The first atomic bomb test in New Mexico happened on 16 July 1945, after which Oppenheimer uttered a line that, along with his trademark fedora and pipe, has become quintessential to his public image.

“Now I am become Death, the destroyer of worlds,” he observed after the so-called Trinity Test, quoting a sacred Hindu text in a reminder of his acumen as a philosopher as well as a scientist.

A few weeks after, death followed on an unimaginable scale. On 6 August, a uranium-based bomb named Little Boy was detonated over Hiroshima; and another, Fat Man, was dropped on Nagasaki three days later.

The latest blast was larger larger than the bomb dropped on Japan's Nagasaki in 1945

Both cities were left unrecognisable, 200,000 people died, and Japan surrendered. Oppenheimer was shaken.

“Right up until the dropping of the bomb on Hiroshima, he had no moral qualms whatsoever,” says Prof Monk.

“Even when the Germans surrendered (on 7 May 1945), and it was obvious the Americans were still going to use the bomb against the Japanese, he had no qualms.

“But he thought one demonstration of the awesome power of this weapon was enough.”

A new world

Despite its undoubted role in ending the Second World War, which cost the lives of some 90 million people, Oppenheimer was changed by the atomic bomb, believing it made the prospect of future conflict “unendurable”.

“It has led us up those last few steps to the mountain pass; and beyond there is a different country,” he said in 1946, later signalling his opposition to his government’s plan to develop even bigger nuclear weapons.

Oppenheimer was ignored and held in deep suspicion, and his security clearance at the Atomic Energy Commission eventually rescinded. He died of lung cancer in 1967 with none of the power he once yielded.

Nuclear weapons have not been used again, but the threat lingers. America and Russia’s arsenals are far smaller than their Cold War peak, but they hold 90% of an estimated global stockpile of 13,000 weapons.

Other nuclear powers include China, India, Pakistan, and North Korea. Like Putin, Kim Jong Un has on several occasions threatened to use them. The Nuclear Threat Initiative, an organisation focused on reducing nuclear and biological threats, says the world could be “sleepwalking into a nuclear disaster”.

Ever since Oppenheimer witnessed the Trinity Test in the New Mexico desert, Cynthia C Kelly says there’s been “no way to put the genie back in the bottle”.

‘Nuclear weapon threat never goes away’

Beyond the mountain

While Oppenheimer failed in his post-war efforts, his work is the best example world leaders have of why they wouldn’t want to risk “mutually-assured destruction” by launching a nuclear weapon.

Two cities devastated beyond recognition have seemingly served as the ultimate deterrence.

“Oppenheimer was invited to say he regretted developing the atomic bomb many times, most prominently when he visited Japan, and his answer was always no,” says Prof Monk.

“It can be argued the fact the weapons have never been used again shows deterrence works.”

Beyond deterrence, the Manhattan Project also unleashed an era of science and innovation still being felt today, including nuclear energy vital to weaning ourselves off greenhouse gases.

Last year, American scientists performed the first-ever nuclear fusion experiment to achieve net energy gain, paving the way for a “clean energy source that could revolutionise the world”.

Some experts have called for a Manhattan Project-style initiative to combat climate change, leveraging the same urgency and determination to tackle a crisis that threatens us all. The startling rise of artificial intelligence, already compared to the threat of nuclear weapons by its very creators, may present another such opportunity.

Energy: Is fusion the future?

Unfortunately, nothing seems to focus the minds quite like war.

“Weapons are one part of the nuclear story, and that will be with us until we blow ourselves up,” says Kelly.

“Hopefully that won’t happen and, as Oppenheimer put it, we can see beyond the mountain.”

They are hurting but managing to find hope in 'tomorrow' - the residents who have lost everything in the LA fires

They are the displaced and there are tens of thousands of them, 600 in an evacuation centre we visited.

From elderly people who fled without their medication, to pregnant mothers desperate to escape the smoke, they had nowhere else to go.

Jim Mayfield, who has lived in the northern suburb of Altadena for 50 years, wept as he told me his dogs, Monkey and Coca, were all he had left.

He said: “The fire was coming down, a ball of fire, it hadn’t made it to my house, but then I woke up and I seen it so I had to start evacuating.

“I had to grab my dogs, I didn’t have enough water and my house is burned down to the ground.”

Sheila Kraetzel, another elderly resident, relived the sense of terror as homes were engulfed by the flames.

She said: “I smelt smoke, I was sleeping, and my dog alerted me that there was trouble.

“When I looked outside, there were embers floating across my yard.

“My whole neighbourhood is gone.”

“It was a beautiful, unique place,” she added, smiling.

Asked how she could smile, she fought back tears and replied: “Well, there’s tomorrow you know.”

How anyone could find hope amid the destruction we have witnessed here is beyond me.

There are people handing out food and water, medical staff doing what they can. Volunteers have rallied from far and near.

Buildings destroyed in fires

One of them, Stephanie Porter, told me it felt “heavy” inside the centre.

“You walk through and see the despair on people’s faces, not knowing what their next step is, not knowing if their house is still standing,” she said.

“I had to take a few moments… and kind of cry, and then you go back to serve.

“It just breaks your heart.”

Three miles up the road, Altadena resembles a war zone, but residents have not been allowed to return.

When they finally do, they’ll discover there’s nothing left of the material lives they left behind.

Sam Moore, who sang Soul Man in the duo Sam & Dave, dies

Sam Moore, who sang Soul Man and other 1960s hits in the legendary Sam & Dave duo, has died aged 89.

Moore, who influenced musicians including Michael Jackson, Al Green and Bruce Springsteen, died on Friday in Coral Gables, Florida, due to complications while recovering from surgery, his publicist Jeremy Westby said.

No additional details were immediately available.

Moore was inducted with Dave Prater, who had died in a 1988 car crash, into the Rock and Roll Hall of Fame in 1992.

The duo, at the Memphis, Tennessee-based Stax Records, transformed the “call and response” of gospel music into a frenzied stage show and recorded some of soul music’s most enduring hits, including Hold On, I’m Comin’.

Many of their records were written and produced by the team of Isaac Hayes and David Porter and featured the record label’s house band Booker T & the MGs.

Sam & Dave faded after their 1960s heyday but Soul Man hit the charts again in the late 1970s when the Blues Brothers, John Belushi and Dan Aykroyd, recorded it with many of the same musicians.

Moore had mixed feelings about the hit becoming associated with the Saturday Night Live stars, remembering how young people believed it originated with the Blues Brothers.

Sam & Dave broke up in 1970 and neither had another major hit.

Moore later said his drug habit played a part in the band’s troubles and made record executives wary of giving him a fresh start.

He married his wife Joyce in 1982, and she helped him get treatment for his addiction that he credited with saving his life.

Moore spent years suing Prater after his former partner hired a substitute and toured as the New Sam & Dave.

He also lost a lawsuit claiming the pair of aging, estranged singers in the 2008 movie Soul Men was too close to the duo.

In another legal case, he and other artists sued multiple record companies and the American Federation of Television and Radio Artists in 1993, claiming he had been cheated out of retirement benefits.

Despite his million-selling records, he said in 1994 his pension amounted to just 2,285 US dollars (£1,872), which he could take as a lump sum or in monthly payments of 73 US dollars (£60).

“Two thousand dollars for my lifetime?” Moore said at the time. “If you’re making a profit off of me, give me some too. Don’t give me cornbread and tell me it’s biscuits.”

Moore wrote Dole Man, based on Soul Man, for Republican Bob Dole’s 1996 presidential campaign and was one of the few entertainers who performed at President Donald Trump’s inaugural festivities in 2017.

Eight years earlier, he objected to Democratic presidential candidate Barack Obama’s use of the song Hold On, I’m Comin’ during his campaign.

LA fires: Data and videos reveal scale of 'most destructive' blazes in modern US history

The fires that have been raging in Los Angeles County this week may be the “most destructive” in modern US history.

In just three days, the blazes have covered tens of thousands of acres of land and could potentially have an economic impact of up to $150bn (£123bn), according to private forecaster Accuweather.

Sky News has used a combination of open-source techniques, data analysis, satellite imagery and social media footage to analyse how and why the fires started, and work out the estimated economic and environmental cost.

More than 1,000 structures have been damaged so far, local officials have estimated. The real figure is likely to be much higher.

“In fact, it’s likely that perhaps 15,000 or even more structures have been destroyed,” said Jonathan Porter, chief meteorologist at Accuweather.

These include some of the country’s most expensive real estate, as well as critical infrastructure.

Accuweather has estimated the fires could have a total damage and economic loss of between $135bn and $150bn.

“It’s clear this is going to be the most destructive wildfire in California history, and likely the most destructive wildfire in modern US history,” said Mr Porter.

“That is our estimate based upon what has occurred thus far, plus some considerations for the near-term impacts of the fires,” he added.

The calculations were made using a wide variety of data inputs, from property damage and evacuation efforts, to the longer-term negative impacts from job and wage losses as well as a decline in tourism to the area.

The Palisades fire, which has burned at least 20,000 acres of land, has been the biggest so far.

Satellite imagery and social media videos indicate the fire was first visible in the area around Skull Rock, part of a 4.5 mile hiking trail, northeast of the upscale Pacific Palisades neighbourhood.

These videos were taken by hikers on the route at around 10.30am on Tuesday 7 January, when the fire began spreading.

At about the same time, this footage of a plane landing at Los Angeles International Airport was captured. A growing cloud of smoke is visible in the hills in the background – the same area where the hikers filmed their videos.

The area’s high winds and dry weather accelerated the speed that the fire has spread. By Tuesday night, Eaton fire sparked in a forested area north of downtown LA, and Hurst fire broke out in Sylmar, a suburban neighbourhood north of San Fernando, after a brush fire.

These images from NASA’s Black Marble tool that detects light sources on the ground show how much the Palisades and Eaton fires grew in less than 24 hours.

 

On Tuesday, the Palisades fire had covered 772 acres. At the time of publication of Friday, the fire had grown to cover nearly 20,500 acres, some 26.5 times its initial size.

The Palisades fire was the first to spark, but others erupted over the following days.

At around 1pm on Wednesday afternoon, the Lidia fire was first reported in Acton, next to the Angeles National Forest north of LA. Smaller than the others, firefighters managed to contain the blaze by 75% on Friday.

On Thursday, the Kenneth fire was reported at 2.40pm local time, according to Ventura County Fire Department, near a place called Victory Trailhead at the border of Ventura and Los Angeles counties.

This footage from a fire-monitoring camera in Simi Valley shows plumes of smoke billowing from the Kenneth fire.

Sky News analysed infrared satellite imagery to show how these fires grew all across LA.

The largest fires are still far from being contained, and have prompted thousands of residents to flee their homes as officials continued to keep large areas under evacuation orders. It’s unclear when they’ll be able to return.

“This is a tremendous loss that is going to result in many people and businesses needing a lot of help, as they begin the very slow process of putting their lives back together and rebuilding,” said Mr Porter.

“This is going to be an event that is going to likely take some people and businesses, perhaps a decade to recover from this fully.”
