The UK government is reportedly reviving its Cold War-era “War Book” to prepare for the potential threat of war, as tensions rise amid growing concerns over global instability. The government’s updated plans, which include guidelines for schools, hospitals, police forces, and the public, reflect the nation’s readiness for a possible conflict.
Air Chief Marshal Sir Richard Knighton, head of the Armed Forces, confirmed the reintroduction of these plans, which are designed to ensure the country’s preparedness in the event of war. The updated document will focus on strategies that consider modern society, infrastructure, and resources, while drawing lessons from the Cold War era.
The “War Book,” which originated during World War I, includes highly classified documents outlining actions for both military and civilian sectors in times of crisis. These documents cover everything from school closures and hospital evacuations to food rationing and safeguarding national treasures. While the plans were once regularly updated and exercised, they had been quietly shelved in the early 2000s after the Cold War ended.
Now, however, the UK faces mounting threats, particularly from Russia, and the government is gearing up for potential conflict, including bolstering its military budget. The UK is set to increase defense spending from just over 2% of GDP to 3.5% by 2035, though some experts have criticized delays in announcing a crucial 10-year Defense Investment Plan. This delay has led to frustration within the defense industry, as promised funding remains unallocated.
Sir Richard emphasized the importance of thinking differently about national resilience, particularly in modern infrastructure sectors like water, electricity, and transport, which must be prepared for threats beyond traditional warfare. The government’s focus on national infrastructure security and defense readiness highlights the growing challenges facing the UK as global tensions escalate.
The Ministry of Defence has also raised concerns about the rising threats to peace, which could disrupt the relative stability the UK has enjoyed over the past three decades. As the country braces for potential danger, officials stress the need for the public to be informed and prepared, encouraging citizens to understand their role in supporting the military and national defense efforts.
