From Britain’s new preparedness campaign to emergency planning across Europe, governments are urging households to prepare for disruptions caused by extreme weather, cyberattacks and potential conflict.
Governments across Europe are encouraging citizens to keep emergency supplies of food, water and other essentials at home, reflecting growing concerns about the vulnerability of critical infrastructure to natural disasters, cyberattacks and military conflict.
The warnings do not necessarily signal an approaching war. Instead, they reflect a broader effort to prepare populations for emergencies that could interrupt electricity, communications, transportation and access to basic necessities.
On Oct. 22, 2026, the United Kingdom launched its “Be Ready” public-awareness campaign, encouraging households to prepare for at least three days of disruption. According to the British Cabinet Office, the three-year initiative emphasizes practical measures, including maintaining supplies of nonperishable food, bottled water, flashlights and emergency communications equipment.
Although the campaign is new, Britain has published household preparedness recommendations since May 2024.
A Growing International Preparedness Effort
Britain is not alone.
A Sept. 22, 2026, report by LADbible detailed similar recommendations across Europe, including Germany, France, Poland, Ireland, Sweden, Finland, Denmark and Estonia.
The recommendations vary considerably. Germany’s Federal Office of Civil Protection and Disaster Assistance advises households to aim for 10 days of self-sufficiency, although even three days of supplies would be beneficial.
France, Poland and several other European countries recommend approximately 72 hours of emergency provisions, while Sweden and Estonia advise preparing for longer disruptions.
These recommendations are not all new. Some represent longstanding national preparedness policies, while others have been updated or promoted more prominently in recent months.
In March 2025, the European Commission introduced its Preparedness Union Strategy, encouraging residents to maintain sufficient essential supplies for at least 72 hours.
The strategy specifically identifies geopolitical tensions, cybersecurity threats, climate change and natural disasters as reasons for strengthening Europe’s emergency response capabilities.
Preparing for Infrastructure Failure
The concerns extend beyond Europe.
An Oct. 26, 2026, Fortune report described a Pentagon initiative known as FORTRESS, under which major U.S. military installations would reportedly be required to sustain essential operations for at least 90 days without external support.
The proposed measures include independent electricity generation, backup communications and reserves of critical supplies.
The reported 90-day requirement remains a developing military planning objective, not an established operational capability.
Meanwhile, Japan continues to emphasize disaster preparedness, particularly in response to earthquakes, flooding and other natural hazards. However, a specific new Japanese stockpiling initiative announced during the past three months has not been independently verified.

What Are Governments Anticipating?
Three overlapping concerns emerge from the official guidance: military conflict and sabotage, cyberattacks against essential infrastructure, and increasingly disruptive natural disasters.
Modern societies depend on interconnected systems. A prolonged electrical outage could affect water treatment, electronic payments, telecommunications and food distribution simultaneously.
The convergence of civilian preparedness campaigns and military resilience planning is noteworthy, but there is no verified evidence that these initiatives are coordinated responses to a specific imminent threat.
What they reveal is a changing understanding of national security: Governments increasingly recognize that resilience begins not only with military defenses and emergency services, but also with households capable of managing the first critical days of a crisis.
The question is no longer simply whether a disaster might occur, but how prepared communities would be if essential systems suddenly stopped working.
