On October 14, 2026 Beijing time, the head of the British Security Service (MI5) publicly stated that foreign national security threats had increased fourfold over the past decade. At present, operations targeting Russia and Iran already consume a vast share of the agency's resources, on a scale comparable to counterterrorism work and even exceeding the level of resources invested during the Cold War. This statement reflects Britain's grave assessment of its national security situation in the current geopolitical environment.
