The survey, which also found that over half of those questioned felt Britain is poorly prepared for war, was released to coincide with today's launch of a private initiative to try to help bolster national resilience.
Lady Olga Maitland, founder of an organisation called the Resilience Imperative, said: "This will be a national campaign, non-partisan and independently funded, working with a coalition of organisations across all sectors of society, informing all corners of society from individuals to the financial and business sectors, and the communities up and down the country.
"We aim to inform policy debate and reinforce resolve as a cornerstone of national defence."
The Resilience Imperative is a small, donor-funded outfit.
The fact it is seeking to generate wider public awareness about this topic, rather than central government, signals an emerging awareness among the UK population of the importance of reviving the kind of national resilience that was second nature during the Cold War, as highlighted by The Wargame podcast by Sky News and Tortoise Media.
We all need to think about resilience, says ex-commander
A particular focus of the self-initiated push is to help strengthen the UK's resilience to attacks that already happen under the threshold of conventional war - such as cyber hacks and disinformation operations designed to influence minds and undermine democratic rule.
General Sir Richard Barrons, a former top military commander and one of the authors of a major review of defence published last year by the government, is supporting the initiative.
He said: "Now is the time for every citizen, enterprise and institution, including government, to make resilience an everyday part of how we think and act.
"Doing so keeps us safer when events turn against us and restores a key foundation of credible deterrence in the face of those who would harm us. Public awareness and engagement remain low, and resilience is too often treated as a technical issue rather than a national one."

A new 'war book' for Britain
Air Chief Marshal Sir Richard Knighton, the head of the armed forces, said in January that the government is committed to producing a "national defence plan" - effectively a modern version of what used to be called the Government War Book.
Drawn up during the First World War and maintained until the turn of the century, this was a comprehensive set of plans for the whole country - from the armed forces, hospitals and the police to industry, schools and even art galleries - to transition from peace to war.
It was shelved after the Soviet Union collapsed.
Sky News first revealed the absence of a modern national defence plan two years ago.
Sir Richard told MPs that work to draw up a new version is underway and is led by the Cabinet Office, as it is a whole-of-government effort, though he said the military component - which the Ministry of Defence is responsible for - would be finalised this year.
What else does the poll tell us?
Public First, a policy and research consultancy, will present the findings of its poll on public attitudes about threats, war and resilience today. It was not immediately clear how many people were questioned to produce the numbers.
As well as highlighting the proportion of the population who think war involving the UK could happen within the next five years, the research also found that only 42% of people would feel compelled to act if Britain was threatened.
In addition, the data signalled a shift in perception about the US - once a steadfast ally of the UK and NATO. The survey found 57% of people regarded the US as a threat, after Russia, Iran, North Korea and China.
The Netflix drama, which follows the story of a teenage boy arrested over the murder of a classmate, leads the field with 11 - including five acting nods for stars Stephen Graham, Erin Doherty, Owen Cooper, Ashley Walters and Christine Tremarco.
It is followed by A Thousand Blows - another series starring both Graham and Doherty - which has seven BAFTA nods, while Star Wars prequel series Andor and Trespasses, set in Northern Ireland during The Troubles in the 1970s, each have six.
The Celebrity Traitors, the most-watched series on British TV in 2025, according to research body Barb, has five nods - including best entertainment performance for host Claudia Winkleman.
In the news coverage category, Sky News is shortlisted for its special programme, Gaza: Fight For Survival, alongside BBC Newsnight and Channel 4 News.
Adolescence broke streaming records after its release in March 2025 and Cooper made history at the Emmys later in the year, by becoming the youngest-ever acting award recipient, at 15.
The series is up for the best limited drama BAFTA, alongside I Fought The Law, Trespasses, and What It Feels Like For A Girl.
Doherty is nominated twice in the acting categories - as a supporting actress for Adolescence, and lead actress in A Thousand Blows - which is nominated for best drama alongside Blue Lights, Code Of Silence, and This City Is Ours.
Aimee Lou Wood also has a double nomination - leading actress for Film Club, and supporting actress for The White Lotus.
Amandaland, Big Boys, How Are You? It's Alan (Partridge), and Things You Should Have Done are the nominees in the scripted comedy category.
Some 124 programmes are in the running for awards in total. Of the 44 nominees in the performance categories, Cooper, Doherty, Walters and Tremarco are among 21 who are shortlisted for the first time.
The first-time performance nominees also include big names such as Bob Mortimer (Last One Laughing), Jodie Whittaker (Toxic Town) and Paddy Considine (MobLand).
BAFTA chief executive Jane Millichip said 2025 had been an exceptional year for television and praised all the nominees.
"From powerful documentaries and stand-out comedy to homegrown drama and the international series that captured global attention, this year's nominees demonstrate a medium at its creative peak," she said. "It's especially exciting to see so many first-time performance nominees, showcasing the vibrant new talent shaping the future of our industry."
The BAFTA TV Awards also celebrate the best TV moment of the year, with nominees this year including memorable scenes from Adolescence, Celebrity Traitors, Blue Lights, Last One Laughing, Big Boys and What It Feels Like For A Girl.
Comedian and actor Greg Davies will host the ceremony on Sunday 10 May.
The TV nominations announcement comes after last month's BAFTA film awards, which ended in controversy after a racial slur was shouted out by Tourette's campaigner John Davidson, who was there to celebrate a film about his life, and left during the BBC's broadcast of the programme.
Four ambulances were destroyed in the blaze following a "loud explosion" that erupted at 1.40am on Monday at the base for volunteer group Hatzola in Golders Green.
Metropolitan Police said CCTV footage showed three hooded individuals pouring accelerant on the parked vehicles, with investigators analysing hours of footage to identify the suspects.
Is Iran behind the attack?
Islamist group Harakat Ashab al-Yamin al-Islamia (HAYI) has claimed responsibility online for the attack, which is so far being treated as an antisemitic hate crime rather than a terror attack.
It is a newly formed group believed to be aligned with Iran and appears to have posted a video on Telegram showing a map of the location of the attack and the ambulances on fire.
The Met said detectives were aware of the claim of responsibility and were working to determine its authenticity.
Commissioner Sir Mark Rowley said while it was "too early" to attribute the attack to Iran, the "rapid growth in recent years of Iranian state threats is grave".
"Britain's Jewish community has in recent years been increasingly targeted by individuals, groups and hostile states, intent on spreading fear, hate and harm," he warned.
We must stand together, says PM
Prime Minister Sir Keir Starmer condemned the incident as a "deeply shocking, antisemitic attack", amid criticism from Jewish leaders that the government needed to do more to combat anti-Jewish hate.
"Antisemitism has no place in our society, and it's really important we all stand together at a moment like this," he said.
On Monday night, about 250 protesters - including many waving Israeli flags and signs saying, "no Jew hate" - gathered in Golders Green, with some chanting "Keir Starmer, Jew harmer".

'We need to root out this hatred'
Home Secretary Shabana Mahmood said the attack was an "attack on this country and on us all".
"Jewish life in this country is indivisible from our national life," she told the Commons.
"Freedom of Jewish worship is an embodiment of who we are - as is the freedom of British Jews to go about their lives in safety and without fear."
Conservative leader Kemi Badenoch said there had been an "increase in the hatred of Jews" and Jewish people wanted to see actions "not just words".
"We need to root out this hatred from its source. It's coming from many places, a lot of misinformation, and even in some extreme cases, extreme Islamist groups," she said.
Israel's president expressed the country's "strength and solidarity" with Britain's Jewish community after the attack.
"We will continue to stand together shoulder-to-shoulder with you in the critical fight against antisemitism," he said.
The UK's chief rabbi Sir Ephraim Mirvis said the "horrific" attack was an "act of deep evil", adding that there had been an increase in antisemitic incidents across the world.
"It's an outright miracle that nobody was injured," he said.
Reanne Coulson was heard screaming and crying for help five weeks before she was discovered near a bridleway, Warwick Crown Court heard.
Mohammed Durnion, 42, did not murder her, jurors concluded. But they found him guilty of manslaughter.
Durnion had claimed Ms Coulson died from a drugs overdose after an argument on 21 May last year.
But prosecutors told the court he strangled the 33-year-old in a deliberate attack and feigned a mental health crisis when police arrived at his flat in Paynes Lane, Coventry, after a 999 call.
Officers searched the property using a torch from a mobile phone but didn't find Ms Coulson's body - which is believed to have been hidden under a mattress.
Durnion moved Ms Coulson after police left and her body was found in Binley Woods more than five weeks later. It had been partially set alight with petrol.
The killer was arrested on 24 June and led police to the burial site three days later.
Video shows him pointing to undergrowth and telling officers, "she is under there" and saying the body is "deep enough".
Adam Moore, 39, Durnion's friend, was also found guilty of assisting an offender by helping hide the corpse in the woods.
The trial was told Ms Coulson, a sex worker who was 5ft 1in and under nine stone, had gone missing on 21 May after going to a support group at a Catholic church where she seemed well.
