Although much is written and televised about British history, especially the ‘Good’ Second World War, it is surprising how little most people actually know about the politics of the war and of the Anglo-American alliance that was forged during it and which has persisted to this day. Prime minister Winston Churchill’s wartime leadership is extolled – to a high degree, rightly – to the heavens. After all, he vehemently opposed the appeasement of the Nazis by the majority of the British establishment as German tanks rolled into one country after another in the 1930s.Churchill is famous or infamous for much else of course – especially in India, then under the jackboot of British colonial rule – including the Bengal famine that killed millions. He is also known more widely as the leader who forged the United Kingdom-United States ‘special relationship’ – the alliance at the heart of British foreign policy and strategy since 1945. To sell the wartime alliance, Churchill weaved a potent myth of shared language and history, of liberal heritage and culture going back centuries to the Magna Carta in 1215.Yet, this was largely smoke and mirrors.The Anglo‑American “special relationship” emerged during the Second World War not as an expression of natural affinity or cultural destiny, but as a contingent political project forged by elites under conditions of acute power inequality and colonial-geopolitical crisis. Its origins lay as much in domestic elite networks and interest groups on both sides of the Atlantic as in formal state‑to‑state diplomacy.British business lobbies such as the Federation of British Industries, trade unions, financial actors in the City of London, and elite think tanks like Chatham House worked alongside official institutions – the Foreign Office, Treasury, and Cabinet – to press for closer ties with the United States (US). Parallel elite formations in the US, most notably the Council on Foreign Relations, performed a similar function.Also read: Independent India and the Secret UK-US Deal That Changed It AllBut not all political forces in Britain supported this. Hardline colonialists wanted to continue the Empire strategy of centuries-duration – to hold onto India and empire markets and imperial preference. Some, including among elite circles, wanted an alliance with the Soviet Union to continue after 1945. Others promoted closer relations with Europe. But the dominant voices threw in their lot with the Americans, knowing that the power imbalance was tilting evermore towards the rising superpower, and would drag Britain along with it on its path to global domination.At the heart of this convergence was Britain’s declining global position. Facing imperial overstretch and existential military threat, British elites saw US support as essential not only to survival in wartime but also to preserving influence in the postwar order. The resulting alliance was thus driven less by sentiment as Churchill claimed than by elite bargaining within a shifting global hierarchy – an unequal partnership from its inception.Courting America: Soft Power and Strategic Calculation, 1939-1941This elite strategy was on vivid display in the 1939 state visit of King George VI and Queen Elizabeth to the US – the first by a reigning British monarch. Britain was in a position of deep vulnerability. Nazi Germany had already annexed Austria, dismantled Czechoslovakia and was about to invade Poland. Under Prime Minister Neville Chamberlain, British leaders sought to cultivate American sympathy and support while countering powerful ‘isolationist’ currents such as the America First movement. This was especially the case once it became clear that Nazi Germany and the Soviet Union would not go immediately to war after the non-aggression agreement reached in August 1939.President Franklin D. Roosevelt hosted the royal visit with elaborate ceremony – formal dinners, public appearances, a Potomac cruise, and symbolic acts at Arlington and Mount Vernon. The objectives were unmistakable: to humanise Britain, soften memories of empire, and frame Anglo‑American cooperation as natural and urgent. Royal diplomacy served as soft power, but it did not override US strategic caution.American policy remained guided by hard calculation. Roosevelt and US planners were not prepared to commit fully to a Britain that might collapse under the weight of Nazi Blitzkrieg. The language of kinship – “kith and kin,” Anglo‑Saxon ties – helped justify limited assistance, but it did not drive decision‑making. Instead, Washington waited to see whether Britain could survive.The Battle of Britain as Strategic Litmus TestThat test came in the summer of 1940. After the collapse of France, Britain appeared isolated and close to defeat. The Battle of Britain (July-October 1940), in which the RAF successfully thwarted the Luftwaffe and prevented a German invasion, proved decisive not only militarily but politically.In the US, policy was constrained by neutrality laws, mass war‑weariness after World War I, and Roosevelt’s looming re‑election campaign. US strategy initially focused on hemispheric defence, with many officials assuming that a Nazi‑dominated Europe was a plausible – perhaps likely – outcome. Britain’s survival was uncertain, and US elites hesitated to invest heavily in what might prove a losing cause.RAF success altered these calculations. British resilience, aided by radar, organisational superiority, and popular resolve, demonstrated that Britain was not a doomed liability but a viable strategic asset – an “unsinkable aircraft carrier” off the European coast. This perception shift enabled key policy moves: the Destroyers‑for‑Bases agreement (September 1940), growing elite and public sympathy, and ultimately the Lend‑Lease Act (March 1941), which transformed the US into the “arsenal of democracy.”These developments reflected calculated interest rather than emotional solidarity. American leaders scaled up support because Britain had proven militarily useful as a shield against full Nazi domination of Europe, Atlantic sea lanes, and global resources. Had Britain failed, US engagement might well have remained limited to hemispheric defence in preparation of a full scale Nazi onslaught.US caution and planning for a Nazi‑dominated EuropeStephen Wertheim’s analysis sharpens this realist interpretation. In the immediate aftermath of France’s collapse, US planners actively contemplated a world in which Nazi Germany dominated continental Europe. Within the Council on Foreign Relations and parts of the Roosevelt administration, postwar scenarios envisioned an American “quarter sphere” focused on the Western Hemisphere – economically self‑sufficient and defensible even in the face of a hostile European bloc.This was not ideological sympathy for fascism, but cold realpolitik. Transoceanic invasion fears were minimal, and American security was not perceived as immediately threatened. Britain’s possible defeat was treated as a strategic contingency rather than a catastrophe. Only when Britain demonstrated its capacity to endure did US thinking pivot toward broader global leadership.By late 1940, planners shifted from a limited hemispheric vision toward a “Grand Area” strategy, setting the foundations for US global supremacy. The Battle of Britain, in this sense, was not merely a military victory but the pivotal demonstration that rewrote American grand strategy.Elite bargaining and the formation of the postwar orderAn elite‑driven account of the matter complements and deepens this analysis. British elites – business, financial, intellectual, and bureaucratic – mobilised aggressively to secure US backing, often framing their appeals in liberal internationalist or cultural terms. But these narratives were instrumental, not causal. Declining power compelled Britain to seek American patronage, while trying to preserve as much autonomy and influence as possible within the emerging order.This realist synthesis debunks nostalgic narratives of the alliance as a natural outgrowth of cultural or ideological affinity. US global supremacy itself was a deliberate choice born from historical developments aligning with 1940s contingencies – not reluctance or idealism, but a recalibration to impose order by force where trade and interests required it. This dovetailed on the British side: declining power compelled outreach, shaped by domestic lobbies seeking to leverage America without full surrender of autonomy.1940 was a realist inflection point. The wartime alliance was not preordained; it was forged through contingency, power calculations, and elite networks once Britain proved its strategic worth. Wartime cooperation – intelligence sharing, combined planning, and military integration – laid the groundwork for postwar institutions such as NATO and Bretton Woods. Britain (grudgingly) accepted junior partnership status in exchange for access and influence within a US‑led liberal order.Persistence of realpolitik: from 1940 to 2026Fast‑forward to the present, and the underlying logic remains strikingly familiar – even as the roles have reversed. In 2026, King Charles III’s planned state visit to the US, hosted by President Donald Trump, again uses royal symbolism to smooth over strained relations. But the structural context is inverted.President Ronald Reagan and Prime Minister Margaret Thatcher Winston Churchill at 10 Downing Street in London, June 9, 1982.

The US, adopting a transactional “America First” posture, explicitly conditions alliance commitments on burden‑sharing. Trump has pressed allies – including the United Kingdom (UK) – to raise military spending far beyond NATO’s 2 percent guideline, linked cooperation in Ukraine to support in other theatres, and demanded European participation in security efforts such as protecting the Strait of Hormuz amid tensions with Iran.Once more, sentimental mythology gives way to power politics. Britain navigates US pressure through elite channels, symbolism, and diplomacy, while Washington recalibrates commitments according to perceived national interest. As in 1940, the “special relationship” endures not because of shared values or heritage, but because mutual – if uneven – strategic utility persists.Conclusion: Myth, power and elite convenienceThe history of the special relationship, from World War II to the present, is best understood as a story of elite bargaining under shifting power conditions. In 1939-40, Britain had to prove its military viability to secure American backing. In 2025-26, the US uses its dominance to extract greater commitments from allies, Britain included. The continuity lies not in kinship but in realpolitik.The pomp and ceremony of royal visits provide a veneer of tradition and harmony. Beneath it lies a bloodstained alliance shaped by strategic calculation, elite interests, and unequal power – sustained not for peoples, but by and for the powers that be.Inderjeet Parmar is professor of international politics and associate dean of research in the School of Policy and Global Affairs at City St George’s, University of London.
