The United Kingdom faces a range of security threats that raise concerns over national preparedness for potential crises, including covert hostile actions and wider conflicts. These vulnerabilities were underscored by recent events, including the discovery that divers from Ukraine may have sabotaged the Nord Stream 2 pipeline in 2022, highlighting the risk that similar attacks could be orchestrated against Britain’s critical infrastructure such as seabed fibre optic cables and gas pipelines.

In a recent reflection on national security, Dominic Murphy, former head of Scotland Yard’s SO15 Counter Terrorism Command, emphasized the increasing boldness of Russia and other adversaries in conducting espionage, sabotage, and assassination plots on British soil. Last week’s court ruling at the Old Bailey condemned two men, allegedly hired by a Russian diplomat, for firebombing properties linked to Labour leader Keir Starmer, including one rented by the Prime Minister’s sister-in-law. Murphy noted that any attempt resulting in serious injury or death to high-profile individuals would be considered an act of war, potentially accelerating NATO’s anticipated timeline for direct conflict with Russia.

Murphy’s insights are informed by his role leading investigations into high-profile incidents, such as the 2018 Salisbury poisonings, where Russian operatives employed a nerve agent in an assassination attempt. The attack, while unsuccessful in its primary target, caused significant public disruption, including street closures and business shutdowns, comparable to pandemic-era restrictions imposed to safeguard public health.

However, Murphy argued that public awareness and readiness for such crises in Britain remain inadequate. He questioned the country’s ability to cope with extended power outages, loss of communication networks, or disruptions to essential services. Unlike during the Cold War, when government campaigns like "Protect and Survive" provided civilians with civil defense guidance, current official communications offer limited practical advice, leaving citizens ill-prepared for emergencies.

Comparing Britain’s approach to other European nations, Murphy pointed to Sweden, the Netherlands, Germany, and Belgium as examples where governments have openly informed their populations about potential disruptions and encouraged individual and community preparedness. In contrast, British intelligence and security agencies have raised warnings without sufficiently explaining the potential everyday impact or recommended responses.

Murphy advocates for a more transparent and pragmatic government strategy that includes clearly defining likely disruption scenarios and making such information accessible in plain language. He suggests setting clear expectations for households and businesses regarding the steps needed to enhance resilience and involving trusted voices from business leaders, local authorities, and community groups to foster a culture of preparedness.

As discussions on defence spending continue, Murphy emphasizes that financial investment alone will not guarantee security. The vital aspect will be the degree to which government institutions and the public trust one another and engage in honest dialogue about the realities of contemporary threats and civil defense readiness. This trust, he argues, could prove decisive in managing future crises.
