Britain has just over 1,000 days to prepare for a potential war with Russia and other adversaries, Defence Secretary Wes Streeting has warned, urging the country to strengthen its military readiness and prepare households for possible national emergencies.
Streeting said Britain’s adversaries could develop the military strength and economic capacity to attack the United Kingdom by 2030. His warning accompanies a government campaign encouraging citizens to stockpile essential supplies in case war, cyberattacks or other emergencies disrupt critical services.
Writing in The Telegraph, Streeting argued that the threat facing Britain has evolved, requiring the government, businesses, households and international allies to improve their preparedness.
“Our adversaries’ willingness to harm us is not new. What has changed is their capacity. By 2030 their force strength and war economy could put them in a position to attack,” he wrote.
He added: “That gives us a little over 1,000 days to complete our mission: to be ready with our allies to fight and win.”
The warning places national defence and civilian preparedness at the centre of Britain’s security debate, amid growing concerns about Russian aggression, attacks on critical infrastructure and the possibility of prolonged disruption to essential services.
Britain Must Prepare for Possible War by 2030
Streeting’s warning is based on an assessment that Britain’s adversaries could become better equipped to threaten the country over the coming years.
The defence secretary pointed particularly to Russia, whose military ambitions and capacity to wage war have become major concerns for European governments and security agencies.
He argued that preparing for conflict is necessary not because war is inevitable, but because credible defence and readiness could help deter an attack.
“To prevent the worst, we have to prepare for it,” Streeting said, referring to the possibility of Russian aggression.
His remarks reflect a broader shift towards treating national security as a responsibility extending beyond the armed forces. Government departments, businesses and ordinary households are being encouraged to consider how they would cope if essential systems were disrupted.
The 2030 timeframe also gives the government a limited period to improve military capabilities and strengthen cooperation with allies.
Streeting said Britain must be prepared to fight alongside its partners and possess the resilience required to withstand threats targeting the country directly.
Government Raises Concerns About State-Sponsored Terrorism
Streeting has also warned that Britain must prepare for what he described as the danger of state-sponsored terrorism from Russia.
Such threats could extend beyond conventional military attacks to include cyber operations, sabotage and efforts to disrupt essential infrastructure.
The defence secretary said the dangers were no longer merely theoretical or confined to distant conflicts.
“In the face of those threats, which are not hypothetical but real, and not somewhere else but increasingly here, we have to step up and take seriously our national resilience as well as our national defence,” he said.
The government’s approach therefore combines military preparedness with efforts to make the wider country more capable of enduring emergencies.
That includes encouraging organisations to assess vulnerabilities, prepare contingency arrangements and consider how essential services could continue operating during a serious disruption.
Britons Told to Stockpile Food and Water
Alongside Streeting’s warning, the government’s “Be Ready” campaign is urging households to maintain enough essential supplies to manage an emergency lasting several days.
Britons are being advised to store up to nine litres of bottled water per person and enough food to last three days.
The recommendations are intended to help people cope if severe weather, cyberattacks or other emergencies temporarily interrupt access to essential services.
Households are also being encouraged to keep blankets, cash, a first-aid kit, a torch with spare batteries and a wind-up FM radio.
These items could prove useful if electricity supplies fail, digital communications become unreliable or normal shopping and transport arrangements are disrupted.
The campaign does not mean that the government has announced an imminent war. Rather, it reflects an effort to encourage practical preparation for a range of emergencies that could affect daily life.
Why the Government Wants Households to Prepare
The concern is that modern societies depend heavily on interconnected systems that can be vulnerable during a major crisis.
Electricity networks, communications, banking, healthcare and transport services may all be affected by severe weather, technical failures or deliberate attacks.
If several systems are disrupted simultaneously, households could struggle to obtain food, withdraw money, communicate with relatives or access essential services.
Maintaining a modest supply of basic necessities could help families remain self-sufficient while authorities work to restore normal operations.
Streeting said the government wanted households and businesses to examine their preparedness rather than assume that essential services would always remain available.
“It’s really important that we ask households and businesses are they prepared?” he said.
The campaign places particular emphasis on planning before a crisis occurs, when supplies and emergency assistance may be easier to obtain.
Andy Burnham Urges Britons Not to Panic
Prime Minister Andy Burnham has also encouraged people to keep food and water at home in case emergencies interrupt normal services.
Burnham sought to distinguish sensible preparation from alarmism, stressing that households should take practical steps without assuming that disaster is imminent.
“It’s not about panicking…It’s about just taking sensible measures to have enough in the house to tide you over should there be a difficult situation,” he told the BBC.
His comments reinforce the government’s message that emergency preparation should become a routine part of household planning.
Keeping basic supplies available could help families manage temporary interruptions without placing immediate pressure on shops, emergency responders or public services.
However, the guidance also raises questions about how the government communicates security risks without creating unnecessary public anxiety.

Streeting’s warning about a potential conflict by 2030 is a strategic assessment of the threat environment, while the household campaign addresses a wider range of possible emergencies.
The two initiatives share the principle that preparation can reduce vulnerability, even when the exact nature and timing of a crisis remain uncertain.
MI5 Warns of Cyberattacks on Critical Infrastructure
Streeting’s comments come after MI5 Director General Sir Ken McCallum called for a “whole-of-society effort” to confront threats to Britain’s national security.
McCallum has warned that hostile actors could target infrastructure and services on which the public depends, potentially causing serious consequences without launching a conventional military attack.
Among the risks he highlighted were cyberattacks capable of disabling banking services, drones disrupting flights and attacks on hospital computer systems that could interfere with medical treatment.
Such scenarios demonstrate how hostile operations could affect everyday life, even if Britain were not experiencing direct military combat.
A successful attack on a financial network, for example, could prevent customers from accessing banking services. Disruption to hospital systems could affect appointments, patient information and treatment arrangements.
Meanwhile, interference with aviation systems could cause delays, cancellations and wider transport disruption.
Security Threats May Persist Beyond the Current Crisis
McCallum has also cautioned against assuming that the current period of heightened international tension will quickly pass.
Asked whether Britain could return to a less divided and more stable international environment, he said security planning was not based on the expectation that the situation would be temporary.
“Our planning assumption is not that this is a temporary blip and we will all be back to normal by next Christmas,” he said.
He explained that the intelligence community was preparing for an extended period of geopolitical competition.
“We are planning on the basis that, in effect, the period of comparative geopolitical stability following the end of the Cold War has sadly ended and we are back in a more contested era now. We are planning on the basis that these risks will endure.”
The assessment suggests that national resilience will remain an important issue for Britain beyond the immediate political and military circumstances.
Military Readiness and Civilian Resilience
Streeting’s warning highlights two connected challenges: strengthening Britain’s ability to deter or respond to a military attack and ensuring that society can withstand disruption.
Military readiness involves developing the capabilities required to defend the country, coordinate with allies and respond to threats.
Civilian resilience, meanwhile, includes protecting essential infrastructure, preparing businesses for emergencies and helping households manage temporary interruptions to services.
Neither approach guarantees that a crisis can be avoided. However, the government’s argument is that better preparation could reduce the damage caused by hostile actions and improve the country’s ability to recover.
The next few years will therefore be important for Britain’s defence planning, particularly if assessments about the growing military capacity of potential adversaries prove accurate.
Streeting’s central message is that the country should not wait until a threat becomes immediate before preparing for it.
His 1,000-day warning is a call to accelerate defence preparations, strengthen cooperation with allies and encourage a culture of practical emergency readiness across British society.
For households, the immediate advice is straightforward: keep essential supplies available, understand how to respond if services are disrupted and follow official guidance during emergencies. For the government, the challenge is to turn warnings about future threats into effective preparation without suggesting that conflict is certain.
