The 'Special Relationship' between Great Britain and the United States of America is often romanticised as a seamless bond forged in the fires of World War II. However, from 1945 through the late 1970s, the reality was far more turbulent. It was a period defined by Britain’s painful descent from global superpower to an American 'vassal state', and Washington’s opportunistic ascent to global hegemony. This alliance was less a marriage of equals and more a series of strategic divergences, economic ultimatums, and perceived betrayals.
The Financial Dunkirk: 1945–1947
In 1945, Britain stood amongst the victors, but it was a pyrrhic triumph. The nation was bankrupt, its cities were in ruins, and its export economy had evaporated. Having fought the war from its inception, Britain relied entirely on American Lend-Lease. Yet, only one week after the Japanese surrender in August 1945, President Harry Truman abruptly terminated the programme. This 'financial Dunkirk' left the new Labour government, led by Clement Attlee, facing literal insolvency.
Lord Keynes was dispatched to Washington to plead for a $3.75 billion gift, arguing that Britain’s early and lonely stand against Hitler justified American generosity. The American response was chillingly pragmatic. Figures like Will Clayton of the State Department viewed Britain not as a gallant ally, but as a competitor who needed to "put away the begging bowl." To the American public, 75% of whom had initially opposed entering the war, Britain was merely a faded empire attempting to subsidise socialism with American taxes.
The resulting 1946 Anglo-American Loan was not a gift but a hard-nosed business deal. It forced Britain to dismantle imperial trade preferences and make sterling convertible—a move that nearly collapsed the British economy in 1947. For many in London, the reward for losing a quarter of the national wealth was to pay tribute to the nation that had grown rich from the conflict.
Atomic Betrayal and the Independent Deterrent
The sense of betrayal deepened in the scientific arena. During the war, Roosevelt and Churchill had signed secret agreements promising full cooperation on atomic energy. However, in 1946, the US Congress passed the McMahon Act, unilaterally ending all nuclear sharing and making such cooperation an act of treason.
This was a calculated move to ensure American atomic monopoly. To the British, who had contributed significantly to the Manhattan Project, it was a "dishonourable" reneging of a wartime pact. Foreign Secretary Ernest Bevin famously responded with patriotic defiance, insisting that Britain must have its own bomb: "We've got to have the bloody Union Jack flying on top of it." This drive for an independent nuclear deterrent was born not just of Cold War necessity, but of a deep-seated distrust of American reliability.
The Poison Chalice: The Cold War Begins
By 1947, Britain realised it could no longer afford its imperial posture. In a masterstroke of "backseat driving," Ernest Bevin informed Washington that Britain would withdraw its forces from Greece and Turkey within six weeks. He knew this would "scare" the Americans into action.
The result was the Truman Doctrine, which effectively saw the US pick up the reins of global policing. While the Americans viewed this as a burden, some British officials saw it as handing over a "poison chalice." The responsibility of hegemony brought headaches that an isolationist America was initially reluctant to accept.
However, as the Soviets exploded their own bomb in 1949 and China fell to Communism, American pragmatism turned into a "mood of panic." Britain watched with concern as the US began to view the world through the lens of a "Russo-Chinese monolith," fearing that American impetuosity might drag Britain into a nuclear war it could not survive.
The Suez Catastrophe: The End of Sovereignty
The return of Winston Churchill to power in 1951 did little to revive the "Special Relationship." Churchill’s rhetoric about a partnership of equals was met with polite indifference from Truman and later Eisenhower. The fantasy of British influence finally shattered during the Suez Crisis of 1956.
When Egyptian President Nasser nationalised the Suez Canal, Prime Minister Anthony Eden attempted to assert British independence by invading Egypt alongside France and Israel. He kept the Americans in the dark, a deception that infuriated President Eisenhower. Eisenhower did not merely disagree; he actively sabotaged the British effort.
By leveraging a run on the pound and threatening to withhold IMF support, the US forced a humiliating British withdrawal. Suez proved that Britain—and indeed any European nation—was essentially a vassal. A nation that cannot decide when it goes to war without its patron’s permission is not, in any meaningful sense, sovereign. Eden’s resignation marked the end of the last British Prime Minister who tried to act as a primary world power.
The 1960s: Greeks to their Romans
Following Suez, Harold Macmillan adopted a new strategy: Britain would play the Greeks to the American Romans, providing the sophisticated diplomatic counsel to the new, brash empire. This approach found success with John F. Kennedy, who established a genuine rapport with "Uncle Harold."
During the Cuban Missile Crisis of 1962, Macmillan was consulted nightly. However, the underlying power dynamic remained lopsided. When the US cancelled the Skybolt missile programme, Macmillan had to beg for the Polaris system at the Nassau Conference. While he secured the deal, it came at a high price: the French President Charles de Gaulle, seeing Britain as too dependent on Washington, vetoed Britain’s entry into the European Common Market.
The Vietnam Strain and the "Black Watch"
The relationship soured under Lyndon B. Johnson and Harold Wilson. Wilson’s refusal to send even a token force, a single battalion of the Black Watch, to Vietnam infuriated Johnson. The Americans, who had supported Britain in its "darkest hour," felt abandoned. Secretary of State Dean Rusk bitingly remarked, "When the Russians invade Sussex, don't expect us to come and help you."
Simultaneously, Britain’s financial instability forced further retreats. The cancellation of the TSR2 aircraft and the withdrawal from East of Suez signalled the end of Britain’s role as an international policeman. While the US had long pushed for the end of the British Empire, they were now unnerved by the lonely feeling of being the world’s sole gendarme.
1973: The Nuclear Alert and the European Pivot
By the 1970s, Edward Heath sought a revolution in foreign policy. He aimed to play down the Special Relationship, believing Britain’s future lay in Europe, not as a tag-along to America. This independence was tested during the 1973 Yom Kippur War.
When the US placed its global forces, including those in Britain, on nuclear alert without consulting London, the illusion of partnership was stripped away. Heath refused to allow the US to use British bases for resupplying Israel, asserting that British interests were not identical to American ones. Washington was furious, with Nixon warning that Europe must either align with US security goals or go it alone.
The Path to Subservience
The period from 1945 to 1979 was a long, painful lesson in the realities of power. Britain began the era attempting to maintain its status through strategic manipulation and nuclear prestige. By the late 1970s, it had shifted between attempts at European leadership and periods of quiet dependency.
The "Middle Prime Ministers" - Macmillan, Wilson, and Heath - each tried, in their own way, to maintain a shred of British self-respect and independence. However, the trajectory was set. The era concluded with a shift toward the Thatcherite approach, which largely abandoned the quest for an independent course in favour of a closer, more subservient alignment with Washington’s interests.
The "Special Relationship" remained, but by 1979, it was clear that the "specialness" was entirely on American terms.
