United Kingdom

The United Kingdom maintains significant global influence despite leaving the EU. Its military alignment with the United States is the highest of any European country, reflecting the enduring Special Relationship and Five Eyes intelligence partnership. The UK also maintains very strong military ties with France and Japan, demonstrating that its security network extends well beyond NATO's European core. The AUKUS submarine pact with Australia further cements its Indo-Pacific ambitions.

The UK's top allies by composite score are Ukraine, Australia, Canada, Norway, and the United States. The strong showing by Ukraine reflects Britain's leading role in supplying advanced weaponry to Kyiv — the UK-Ukraine relationship is exceptionally strong on diplomatic and regime relations dimensions. Among traditional allies, Canada scores highest in societal relations, reflecting deep Commonwealth cultural ties, while the US leads on military cooperation.

Russia is the UK's top adversary. The military dimension is particularly hostile, and diplomatic relations are among the most adversarial bilateral scores in our dataset. This reflects Britain's hawkish stance on Ukraine, its leadership in Western sanctions enforcement, and incidents like the Salisbury nerve agent attack. Switch to the diplomatic dimension on the map to see the UK's full confrontation arc with Russia and Belarus.

UK-China relations are deeply strained across all dimensions — military, diplomatic, regime relations, and societal. The diplomatic hostility is notable, worse than many NATO members, driven by clashes over Hong Kong, Xinjiang, and Chinese tech restrictions. Despite this, the relationship is less hostile than UK-Russia or UK-Iran, reflecting the economic interdependence that still tempers the confrontation.

Roughly four in ten countries have a positive relationship with the UK, while the majority are neutral, and only a small handful are negative. This distribution reflects Britain's broad diplomatic network through the Commonwealth, NATO, and bilateral trade agreements. Its negative relationships are concentrated among authoritarian regimes: Russia, Afghanistan, North Korea, Belarus, and Iran. Switch between dimensions to see how military partnerships differ from societal connections.

Post-Brexit, the UK maintains strong bilateral ties with individual EU members even as the institutional relationship frayed. France shows very strong military and diplomatic alignment, driven by the Lancaster House defence treaties. Ireland scores lower militarily but higher on societal relations and diplomacy, reflecting the complex post-Brexit border dynamics. The UK is geographically European but culturally Atlanticist — its US military alignment significantly exceeds its score with any EU member state.

UK-India scores show a balanced, moderately strong partnership across all four dimensions. Diplomatic alignment is notably stronger than UK-Turkey or UK-Nigeria, reflecting upgraded trade talks and defence cooperation. Societal relations benefit from the large British-Indian diaspora. However, the relationship remains well below the UK's scores with core Five Eyes partners, suggesting a partnership with significant room to grow.

The UK's deepest rivalries are with Russia, Afghanistan, North Korea, Belarus, and Iran. Iran stands out with strongly negative military and diplomatic scores, reflecting decades of confrontation over the nuclear program, Gulf security, and detained nationals. Belarus is adversarial largely as a proxy of the Russia confrontation. Afghanistan's hostility reflects the Taliban regime's opposition to Western liberal governance rather than any active military conflict.
