The US-China Cyber Conflict and Its Impact on the UK's Cybersecurity Policies

Abstract

This paper explores the geopolitical implications of the U.S.-China cyber conflict and its cascading effects on the United Kingdom’s cybersecurity posture. As the United States and China engage in strategic cyber competition involving espionage, data theft, and digital infrastructure control, third-party states like the UK are compelled to recalibrate their cybersecurity strategies. Employing Realist theory in international relations, the paper explains how power maximization and national sovereignty guide cybersecurity policy decisions in a multipolar digital world. By analyzing the evolution of the UK's cybersecurity frameworks, alliances, and technological investments in response to this competition, the study reveals the cyber domain as an arena of influence where global power dynamics manifest. The research also reflects on how digital sovereignty and multiparty intelligence alliances reshape middle-power behavior in the international system.
