Even though the U.S. was desperately trying to build up its military forces throughout 1941, Roosevelt decided to give the British some of the United States' most advanced weapons. Military aid to Britain was greatly facilitated by the Lend-Lease Act of March 11, 1941, in which Congress authorized the sale, lease, transfer, or exchange of arms and supplies to "any country whose defense the president deems vital to the defense of the United States."

'... We shall go on to the end, we shall fight in France, we shall fight on the seas and oceans, we shall fight with growing confidence and growing strength in the air, we shall defend our island, whatever the cost may be, we shall fight on the beaches, we shall fight on the landing grounds, we shall fight in the fields and in the streets, we shall fight in the hills; we shall never surrender ...'

If Hitler can bring under his despotic control the industries of the countries he has conquered, this will add greatly to his already vast armament output. On the other hand, this will not happen immediately, and we are now assured of immense, continuous and increasing support in supplies and munitions of all kinds from the United States; and especially of aeroplanes and pilots from the Dominions and across the oceans coming from regions which are beyond the reach of enemy bombers.
That was the prospect a week ago. But another blow which might well have proved final was yet to fall upon us. The King of the Belgians had called upon us to come to his aid. Had not this Ruler and his Government severed themselves from the Allies, who rescued their country from extinction in the late war, and had they not sought refuge in what was proved to be a fatal neutrality, the French and British Armies might well at the outset have saved not only Belgium but perhaps even Poland. Yet at the last moment, when Belgium was already invaded, King Leopold called upon us to come to his aid, and even at the last moment we came. He and his brave, efficient Army, nearly half a million strong, guarded our left flank and thus kept open our only line of retreat to the sea. Suddenly, without prior consultation, with the least possible notice, without the advice of his Ministers and upon his own personal act, he sent a plenipotentiary to the German Command, surrendered his Army, and exposed our whole flank and means of retreat.
However, Smithsonian writes that the most surprising thing, is that Churchill’s speech was not broadcast over the radio to the British public, and that most Britons and Americans did not hear the speech until decades later. And the recording that has been heard round the world was actually recorded in 1949, from the comfort of his own home. The House of Commons was not wired for sound in 1940, so any public broadcast would have to be delivered again, specifically for radio. But Churchill was too busy and uninterested to do this, and so radio journalists just reported his words on the air.
The Cold War emerged as the Soviet Union turned Eastern Europe - the invasion route to Russia for centuries - into a military and political buffer between it and the West. Each saw a different reality; The Soviets wanted troops in Eastern Europe to block an attack from the West; the West saw them as a prelude to an attack on the West. Mutual suspicion, misunderstanding, ideological posturing and rhetorical extravagance, and Soviet-style governments in the East locked the two sides in a tense standoff.
Furthermore, I do not dismiss the Gallup polls, although I offer some reasons for thinking that they may have exaggerated the extent of Churchill’s (nonetheless very high) popularity. My point about the inadequacy of ‘yes/no’ questions for ascertaining reactions to his speeches stands. High approval ratings can take account neither of those who supported Churchill politically but who were not that keen on his broadcasts, or of those who thought that the speeches were all very fine but had doubts about his leadership nonetheless. Matthews asks why those surveyed by MO and the Ministry of Information (MoI) should have been less influenced by social pressures than those interviewed by Gallup. To begin with, those who entrusted their diaries to the eyes of strangers clearly were, pretty much by definition, less inhibited than the ordinary run of people. Second, where MO and MoI used face-to-face interviews, it is quite possible that some respondents held back – in other words, there may have been more criticism than the reports reveal. Finally, though, these bodies had other sources of information besides interviews. MO observers attended public places and wrote down what they overheard. MoI too drew on a network of informants, as well as on questionnaires filled in by bodies ranging from W.H. Smith and Sons to the Brewers’ Society. Postal censorship and Special Branch reports were also used.(2) Matthews takes me for task for not quoting more widely from censorship summaries of soldiers’ letters. Obviously, if such documents existed, and if they analysed the political opinions of serving men, they would be a treasure trove of material. Yet, except for the report created in the special circumstances of the Greek crisis, I do not believe that they have been preserved, assuming them to have created in the first place. If I am wrong, and if Matthews knows where these documents are, he will be doing a great service to the profession if he reveals where they are to be found.

Churchill knew that mastering the art of speech-making and writing was very important in a political career; he also believed in his abilities as an orator, despite being relatively inexperienced. During the July 1899 Oldham by-election campaign, he writes to his mother Lady Randolph Churchill of his conviction that he would win the election: “My speech last night at the club produced great enthusiasm ... and there is no doubt that if anyone can win this seat I can”.In the event, although he did slightly better than his running-mate in the polls, he did not win, losing a previously held Conservative seat. He might have been defeated, but he was conscious that in this fight he had not been disgraced. According to the Manchester Courier, “he made a splendid impression on the constituency, but the time was too short”.

10. The mood of Britain is wisely and rightly averse from every form of shallow or premature exultation. This is no time for boasts or glowing prophecies, but there is this – a year ago our position looked forlorn, and well nigh desperate, to all eyes but our own. Today we may say aloud before an awe-struck world, ‘We are still masters of our fate. We still are captain of our souls. House of Commons, 9 September 1941

6. This is no war of chieftains or of princes, of dynasties or national ambition; it is a war of peoples and of causes. There are vast numbers, not only in this island but in every land, who will render faithful service in this war but whose names will never be known, whose deeds will never be recorded. This is a war of the Unknown Warriors; but let all strive without failing in faith or in duty, and the dark curse of Hitler will be lifted from our age. Radio broadcast, 14 July 1940
'This is your victory! It is the victory of the cause of freedom in every land. In all our long history we have never seen a greater day than this. Everyone, man or woman, has done their best. Everyone has tried. Neither the long years, nor the dangers, nor the fierce attacks of the enemy, have in any way weakened the unbending resolve of the British nation. God bless you all.'

The Japanese attack on Pearl Harbor (December 7, 1941) altered, in Churchill’s eyes, the whole prospect of the war. He went at once to Washington, D.C., and, with Roosevelt, hammered out a set of Anglo-American accords: the pooling of both countries’ military and economic resources under combined boards and a combined chiefs of staff; the establishment of unity of command in all theatres of war; and agreement on the basic strategy that the defeat of Germany should have priority over the defeat of Japan. The grand alliance had now come into being. Churchill could claim to be its principal architect. Safeguarding it was the primary concern of his next three and a half years.
Even so, Churchill’s appointment as minister of munitions in July 1917 was made in the face of a storm of Tory protest. Excluded from the cabinet, Churchill’s role was almost entirely administrative, but his dynamic energies thrown behind the development and production of the tank (which he had initiated at the Admiralty) greatly speeded up the use of the weapon that broke through the deadlock on the Western Front. Paradoxically, it was not until the war was over that Churchill returned to a service department. In January 1919 he became secretary of war. As such he presided with surprising zeal over the cutting of military expenditure. The major preoccupation of his tenure in the War Office was, however, the Allied intervention in Russia. Churchill, passionately anti-Bolshevik, secured from a divided and loosely organized cabinet an intensification and prolongation of the British involvement beyond the wishes of any major group in Parliament or the nation—and in the face of the bitter hostility of labour. And in 1920, after the last British forces had been withdrawn, Churchill was instrumental in having arms sent to the Poles when they invaded the Ukraine.
We shall not flag or fail. We shall go on to the end, we shall fight in France, we shall fight on the seas and oceans, we shall fight with growing confidence and growing strength in the air, we shall defend our Island, whatever the cost may be, we shall fight on the beaches, we shall fight on the landing grounds, we shall fight in the fields and in the streets, we shall fight in the hills; we shall never surrender, and even if, which I do not for a moment believe, this Island or a large part of it were subjugated and starving, then our Empire beyond the seas, armed and guarded by the British Fleet, would carry on the struggle, until, in God's good time, the New World, with all its power and might, steps forth to the rescue and the liberation of the Old.
Muller says that the lecture commenced with full "pomp and ceremony," and both Churchill and Truman received honorary degrees from the school, according to National Churchill Museum chief curator Timothy Riley. According to contemporary coverage of the event in the New York Times, a crowd of 8,000 Fulton residents turned up, along with 20,000 visitors "from as far distant as St. Louis." 

The train stopped at the St. Louis station in the early morning of March 5. Churchill took a leisurely breakfast in his stateroom before he and the presidential party switched to a local train for Jefferson City. There, Churchill and Truman entered their open-car limousines for the motorcade into Fulton. Churchill found, to his dismay, that he was lacking the requisite prop—a cigar. So he stopped at a local tobacconist for the purchase.
This brings me, naturally, to the great question of invasion from the air, and of the impending struggle between the British and German Air Forces. It seems quite clear that no invasion on a scale beyond the capacity of our land forces to crush speedily is likely to take place from the air until our Air Force has been definitely overpowered. In the meantime, there may be raids by parachute troops and attempted descents of airborne soldiers. We should be able to give those gentry a warm reception both in the air and on the ground, if they reach it in any condition to continue the dispute. But the great question is: Can we break Hitler's air weapon? Now, of course, it is a very great pity that we have not got an Air Force at least equal to that of the most powerful enemy within striking distance of these shores. But we have a very powerful Air Force which has proved itself far superior in quality, both in men and in many types of machine, to what we have met so far in the numerous and fierce air battles which have been fought with the Germans. In France, where we were at a considerable disadvantage and lost many machines on the ground when they were standing round the aerodromes, we were accustomed to inflict in the air losses of as much as two and two-and-a-half to one. In the fighting over Dunkirk, which was a sort of no-man's-land, we undoubtedly beat the German Air Force, and gained the mastery of the local air, inflicting here a loss of three or four to one day after day. Anyone who looks at the photographs which were published a week or so ago of the re-embarkation, showing the masses of troops assembled on the beach and forming an ideal target for hours at a time, must realize that this re-embarkation would not have been possible unless the enemy had resigned all hope of recovering air superiority at that time and at that place.
But the escalating situation in Europe was getting hard to ignore. Churchill rose to the Prime Ministry on May 10, 1940, coinciding with the end of the so-called “Phoney War,” a period stretching from September 1939, with the declaration of war against Germany, to the spring of 1940, a period with no major military land operations on the European continent. That stagnation ceased after the Nazis invaded Denmark and Norway in April. The Battle of Dunkirk -- which would incur heavy Allied casualties, prompt a Belgian surrender, and precipitate the fall of France -- commenced in May.
The shock of rejection by the nation fell heavily on Churchill. Indeed, though he accepted the role of leader of the parliamentary opposition, he was never wholly at home in it. The economic and social questions that dominated domestic politics were not at the centre of his interests. Nor, with his imperial vision, could he approve of what he called Labour’s policy of “scuttle,” as evidenced in the granting of independence to India and Burma (though he did not vote against the necessary legislation). But in foreign policy a broad identity of view persisted between the front benches, and this was the area to which Churchill primarily devoted himself. On March 5, 1946, at Fulton, Missouri, he enunciated, in the presence of President Truman, the two central themes of his postwar view of the world: the need for Britain and the United States to unite as guardians of the peace against the menace of Soviet Communism, which had brought down an “iron curtain” across the face of Europe; and with equal fervour he emerged as an advocate of European union. At Zürich, on September 19, 1946, he urged the formation of “a council of Europe” and himself attended the first assembly of the council at Strasbourg in 1949. Meanwhile, he busied himself with his great history, The Second World War, six volumes (1948–53).
Historian Andrew Roberts says the impact of Churchill's speeches cannot be underestimated. "An awful lot of people thought that it was impossible to beat the Nazis," Roberts says. "Yet what Winston Churchill did, by constantly putting Britain's peril in the greater historical context of other times that Britain had nearly been invaded, but had been ultimately successful, he managed to tell the British people that this could happen again."
What is important is that the version found on the BBC’s ‘School Radio’ site is the one used in documentaries, such as ITV’s 1973–4 World at War series. It is the version that people, including those who listened to the actual broadcast, think of when they think of this speech. But is it what the British people heard in the summer of 1940? There are hints here and there that Churchill ‘re-recorded’ some of his wartime speeches for Decca Records around 1949. Strangely, none of Churchill’s biographers mention this, and neither does Toye. More’s the pity. It is a mystery that, if solved, could help explain why reactions to Churchill’s broadcasts when they were given differ from the impressions we have of them today.  

Churchill’s place in history is assured; with Hitler he remains a towering political figure of the twentieth century. His courage, determination, and leadership during Britain’s greatest peril mark him for the ages. However unlikely the success of a German invasion of Britain in 1940 now seems—‘‘Overlord in reverse’’—it did not seem so at the time. When some of his fellow Britons and not a few Americans called for capitulation or accommodation, Winston Churchill chomped his cigar, flashed his V-for-victory sign, and uttered a defiant ‘‘No!’’ that echoes down the ages.

Professor Toye commented:“There was a complexity to people’s reactions to Churchill’s speeches at the time, as the evidence shows that they may have liked one bit of a speech and not another section, or liked some speeches but not others. People sometimes changed their minds following discussions with friends or after reading newspaper commentaries; there was not a blanket acceptance and positive reaction. A more measured response to his speeches is in evidence. This is possibly why the speeches didn’t always have the effect now credited to them.”
While largely unstated, one of Churchill’s major concerns was limiting Soviet territorial gains in Europe. Having an eye toward the postwar world, he did not want Stalin in control of formerly democratic nations. However, geopolitics required further cooperation with his unlikely ally, and Churchill met Roosevelt for the last time in Stalin’s domain—Yalta in the Crimea, in February 1945. Victory in Europe was visible by then, though with more hard fighting to come in the Pacific. Roosevelt’s premature death in April ended the original Big Three.
