Churchill vs Stalin: did this one speech cause the Cold War?
It’s 80 years since the war victor delivered his ‘Iron Curtain’ speech, sounding the alarm for a perilous new age. The speech, given as tensions with Stalin soared, is among the most famous in modern history. Yet, asks Richard Toye, has it been misunderstood?

“From Stettin in the Baltic to Trieste in the Adriatic, an iron curtain has descended across the continent.” It was the soundbite of the century – or at least of the Cold War. Uttered by a former prime minister in a speech on 5 March 1946 at a small college in Missouri, its intended audience was far larger than the scholars and public figures assembled in the institution’s gymnasium. The fact that the ex-PM in question was war victor Winston Churchill – and that sitting on stage alongside him was US president Harry S Truman – helped turn this lecture into a world-shaking historical event.

Churchill made a lot of speeches in his long political career. Few of them, however, had the same resounding impact as this warning about the Soviet threat. A set of unique circumstances lent his oration its unusual power – and endowed it with the capacity to shape the language of east-west conflict for decades to come.
The Iron Curtain speech was delivered at a time of acute – and escalating – tensions between the Soviet Union and western powers. It’s often been described as the moment that the starting gun was fired on the Cold War. It’s indisputably among the most momentous pieces of oratory of the postwar period. And yet, for all that, it’s clouded in misunderstanding.
Much of that misapprehension stems from the fact that the speech had surprisingly long roots – roots stretching all the way back to Anglo-Russian imperial conflicts in the late 19th century. When Churchill rose to his feet and addressed his audience at Fulton, he was 71 years old. He was, as he declared himself, a child of the Victorian age. The legacy of the so-called ‘Great Game’ – strategic competition between Britain and Russia in central Asia – was a factor throughout his political career. Even as a schoolboy, he wrote an essay in which he fantasised about a British invasion of Russia and gloated of “the superiority of John Bull over the Russian bear”.
Strangling Bolshevism
Yet Churchill’s attitude to Russia – and even to the USSR – was by no means one of unremitting hostility. And that was reflected in the Fulton speech, too. He was no admirer of tsarist autocracy, and even less so of Soviet communism. But during the First World War he eulogised Britain’s Russian allies, and was distressed when they dropped out of the conflict.

Churchill became the strongest advocate of intervention in the civil war that followed the October Revolution of 1917, and always regretted the failure “to strangle Bolshevism at its birth”. Following Hitler’s rise to power, he began to see the Soviet Union as a counterweight to Nazi Germany, and even as a possible ally. In a March 1939 interview, he asserted that the USSR had “hitherto shown no trace of the aggressive intentions” behind the recent actions of the Germans, the Italians and the Japanese. Even after the Soviets and Germans signed a non-aggression pact that August, he appeared to foresee that the USSR’s national interests would eventually force Stalin into an anti-German posture.
His prediction came true with Hitler’s invasion of the Soviet Union in June 1941. The functional but troubled Anglo-Soviet alliance that followed provides the crucial backdrop to the breakdown in relations that the Iron Curtain speech signalled.
Churchill continued to view diplomacy through a traditional ‘Great Power’ lens. That is to say, history was made via hard bargains between the paramount countries, recognising each other’s spheres of influence and legitimate interests, and often involving the ruthless sacrifice of weaker peoples and nations.

Churchill’s wartime meetings and correspondence with Stalin were based on this principle – and also on the belief that personal relations were crucial, and that his own individual charm could make a difference. He said in 1942 that he “liked Mr Stalin, liked his jokes and his humour, but could have gotten on with him a lot better if he could have talked with him directly instead of through an interpreter”. Combining tough talk with schmoozing and flattery, he believed that mutual recognition of British and Soviet spheres of interest represented the path to a safer future. The Iron Curtain speech of 1946 reflected the continuation of this approach, rather than a radical shift in outlook.
Falling for Stalin’s charms
Churchill, however, oscillated between optimistic and pessimistic interpretations of Soviet behaviour. After the February 1945 Yalta conference – at which the British, Soviet and American leaders discussed the postwar reorganisation of Europe – the prime minister told colleagues: “Poor Neville Chamberlain believed he could trust Hitler. He was wrong. But I don’t think I’m wrong about Stalin.” Yet as the Red Army’s advance progressed, he became increasingly concerned about the prospect of Soviet dominance of Europe. On 12 May, just a few days after VE Day, Churchill wrote to President Truman of the need to reach a concordat with the USSR before the British and American armies ‘melted’ with the onset of peace. “An iron curtain is drawn down between their front,” he added. This was his first rehearsal of a phrase he would later make famous.

Six days later, Churchill lectured the Soviet ambassador, accusing his Kremlin masters of “dropping an iron screen across Europe from Lubeck to Trieste, behind which we had no knowledge of what was happening”. Churchill’s diatribe did not have the desired effect. The ambassador told Moscow that “we need to bear in mind that we are dealing with an adventurer, for whom war is his natural element”. Indeed, Churchill was already pondering ‘Operation Unthinkable’, a military plan – quickly dropped – for a potential military conflict with the Soviets. But at the Potsdam conference of July 1945 (at which the ‘Big Three’ Allied leaders convened once more), he was, in the words of foreign secretary Anthony Eden, “under Stalin’s spell again”. Eden reported that Churchill "kept repeating: 'I like that man.'"

Churchill’s participation in the negotiations was about to be brought to a sudden and unexpected end – for, before the Potsdam conference was concluded, news came through that he had been voted out of power in that summer’s general election. Churchill’s shock electoral defeat was a bitter political and personal blow, but it didn’t have a material impact on Anglo-Soviet relations: the new Labour government carried on foreign policy on familiar lines. When parliament reassembled, Churchill made his first public reference to “the iron curtain which at the moment divides Europe in twain”. His words were reported in the press but did not make headlines, and attracted little comment.
It should be noted that Churchill was now speaking in a new context, following the successful test of the atomic bomb and the destruction of Hiroshima and Nagasaki. Though he could not say so openly, he hoped that the American monopoly of the new weapon would be the lever that would keep Soviet ambitions in check. He was thoroughly conscious of Britain’s weakening global strength, and believed that a strong relationship with the US was key to escaping its precarious position.

For this reason, the message he received from Truman that autumn was a godsend. The president passed on an invitation from the head of Westminster College in Fulton, Missouri to deliver the annual John Findley Green Foundation Lecture on problems of international concern. “This is a wonderful school in my home state,” scribbled Truman on the letter. “Hope you can do it. I’ll introduce you.” Churchill, still harbouring designs of returning to Downing Street, now had an opportunity to relaunch himself on the world stage, as well as to take a holiday in the sun.
During his lengthy absence from home at the start of 1946, Churchill sojourned in Florida and Cuba before travelling to Washington, DC. Truman accompanied him to Fulton by train.
As the train approached Missouri, a crisis was unfolding in Persia (now Iran) on the back of a speech by Stalin that seemed to anticipate conflict with the capitalist powers. The Soviets had failed to withdraw all of their troops from the north of Persia by the deadline that had previously been agreed. But though the president was increasingly incensed by their stonewalling stance, he was not yet ready to lay his fears and frustrations in front of his war-weary populace. With no official responsibilities, however, Churchill could speak frankly in a way that those in government could not.

The bombshell moment
On 5 March, Churchill delivered his remarks before 2,700 people, all of them white. As one black American newspaper noted, the college was “located in a state where Jim Crow is a legal instrument of government and Negro boys and girls are barred from its portals by law”. The mainstream media made little of this shocking fact, but the message contained within the speech itself was regarded as a bombshell.
Churchill’s oration was 46 minutes and 5,000 words long. The ‘iron curtain’ phrase came at the two-thirds mark. It was part of a broader warning about the Soviet Union’s “expansive and proselytising tendencies”, which Churchill backed up with claims about Moscow’s search for “totalitarian control” in the countries of central and eastern Europe.
The Iron Curtain speech was not a Cold War clarion call intended to stoke tensions
Yet despite the muscular rhetoric, scholars now tend to emphasise that the Iron Curtain speech was not a Cold War clarion call intended to stoke tensions. This is another way in which the speech has been misunderstood. Churchill undoubtedly wanted to reset relations through plain speaking, but he also wanted to show the Soviets that he understood their perspective. Hence he stressed his “strong admiration and regard for the valiant Russian people and for my wartime comrade, Marshal Stalin”. He stated that he understood “the Russian need to be secure on her western frontiers by the removal of all possibility of German aggression”. It was necessary, he said, to reach “a good understanding on all points with Russia” under the auspices of the recently formed United Nations.

Over the following days and weeks, few observers paid much heed to the more emollient sentiments in Churchill’s speech. The nuances of the former PM’s words were easily lost in the media tumult. In fact, the forcefulness of his overall message risked exacerbating the problem he was trying to solve.
“Churchill’s speech is sure some blockbuster, as one American paper describes it,” noted one ordinary observer, a female librarian back in Britain. “I read it first in full, and later heard extracts; and I must say that his delivery was so calm and flowing that the parts which had horrified me in print seemed perfectly innocuous as he spoke them.”
Churchill offered not only a diagnosis of the perils of deteriorating east-west relations but also a remedy – and in the US it was the latter that proved especially divisive. He urged that a robust response to the Soviets should be built upon “a special relationship between the British Commonwealth and empire and the United States”. This seemingly innocuous phrase was widely (and correctly) perceived as a concealed call for a military alliance between the UK and the US.
This lit a fire, because former isolationists still distrusted the British empire, and progressive idealists believed that a bilateral pact would be a threat to the integrity of the UN. Leo Amery, Churchill’s former secretary of state for India and Burma, thought it was an error to link the admonitions about the Soviets and the alliance concept together in one speech. “The Americans are intensely suspicious of any attempt to inveigle them into being mere instruments of British policy in the Old World,” observe Amery. Meanwhile, Adam Clayton Powell, the first African American to represent New York in Congress, claimed that Churchill wanted “an English-speaking dictatorship” and “a form of super-nationalism based on race” that would plunge the world once again into war.

Truman had known of the speech’s contents in advance but, when the political kitchen heated up, denied having done so. Britain’s Labour prime minister, Clement Attlee, took refuge in the claim that his government was “not called upon to express any opinion of a speech delivered in another country by a private individual”. However, in private he was less dismissive: “It will certainly have done good if it encourages the Americans to think and to recognise the need for the United States and the British Commonwealth to work together,” he said.
The destiny of the world
It is not clear if Churchill really expected the speech to cause the Soviets to change their attitude – but if so, he failed. “Hitler began his work of unleashing war by proclaiming a race theory, declaring that only German-speaking people constituted a superior nation,” Stalin told the Soviet state-mouthpiece, Pravda. “Mr Churchill sets out to unleash war with a race theory, asserting that only English-speaking nations are superior nations, who are called upon to decide the destinies of the entire world.” With fear spreading, Moscow housewives started panic-buying. The Soviet authorities then tried to calm the public, spreading the message that “Stalin’s interview did not mean that war was in sight”.
Churchill did not start the Cold War at Fulton, he selected its defining image
The Fulton speech may have elicited a frosty reception in Moscow but, within a year, despite the initial misgivings, its once-controversial message had found widespread acceptance in the west. As tensions between America and the Soviet Union ratcheted up further, the 1947 Truman Doctrine committed the US to “support free peoples who are resisting attempted subjugation by armed minorities or by outside pressures”. The doctrine is now seen by some historians as marking the true start of the Cold War. To this day, politicians on both sides of the Atlantic pay lip service to the Anglo-American ‘special relationship’.
And Churchill was not quite done with the Soviet Union. Prime minister again from 1951–55, he ploughed his remaining strength into a vain quest for a rapprochement with the post-Stalin Kremlin. This was not because he had changed his mind; rather, his quest for détente was of a piece with his longstanding approach to great power relations and his belief in the importance of negotiating from a position of strength. He was convinced that the greatest chance of peace lay in convincing the Soviet government that they were confronted by superior force that would be used ruthlessly against them unless they mended their ways. “Then the communists will make a bargain,” he judged.
East-west relations would have continued declining with or without the Iron Curtain speech. Yet although Churchill did not start the Cold War at Fulton, he selected its defining image – and with carefully crafted vocabulary he created an indelible mental picture that influenced all subsequent debate.
Metal coinage
Was Churchill really the first to use the phrase 'Iron Curtain'?
“Iron curtain: a state of rigid censorship and secrecy (coined by Winston Churchill in 1946 to describe the line of demarcation between western Europe and the Soviet zone of influence)”. This was the definition included in the American College Dictionary. But the editors remained uncertain – had Churchill genuinely originated the term? In 1951, a member of that publication’s team wrote to him to find out.
There were good reasons for wondering. The metaphor is based not on conventional domestic drapes but on the fire safety curtains used in theatres. In a 1904 novel, Churchill’s friend HG Wells (pictured) described how, when a character is deprived of his freedom, “an iron curtain… dropped between him and the outer world”. The historian Patrick Wright credits the writer Vernon Lee (a pseudonym for Violet Paget) as being the first to deploy the term in an international relations context. She wrote of “war’s monstrous iron curtain” dividing the two sides after the outbreak of hostilities in 1914.
After the October 1917 revolution, the phrase was used in a new sense. In her 1920 book Through Bolshevik Russia, Ethel Snowden described her arrival in Petrograd as part of a Labour delegation: “We were behind the ‘iron curtain’ at last!”
It is more than possible that Churchill was acquainted with these examples. But, if so, the influence was unconscious. In response to the query about the origins of his words, he replied: “No. I didn’t hear of the phrase before – though everyone has heard of the ‘iron curtain’ which descends in a theatre.” The dictionary definition stood.
The fact that Churchill saw ‘iron curtain’ as a standard expression may explain why he did not do more to attract attention to it. The official title of his speech was ‘The Sinews of Peace’. This, in turn, offers a clue as to why the famous phrase didn’t dominate newspaper headlines. The Daily Express, for example, ran with “CHURCHILL URGES EMPIRE ‘ALLIANCE’ WITH U.S”. The first BBC reporting, on the 11pm radio news, omitted the ‘iron curtain’ passage altogether.
Churchill was a genius with words. But even he did not know which of his own would be best remembered.
