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.
This was such a major speech because it helped convince the US government to focus on the European theatre of war, thus helping Britain rather than focusing on the Pacific theatre. Churchill highlighted the common culture and language and his own American lineage by saying: “I cannot help reflecting that if my father had been American and my mother British, instead of the other way round, I might have got here on my own.”
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 And in 1920, after the last British forces had been withdrawn, Churchill was instrumental in having arms sent to the Poles when they invaded the Ukraine.
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."

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.  
We ask no favours of the enemy. We seek from them no compunction. On the contrary, if tonight the people of London were asked to cast their votes as to whether a convention should be entered into to stop the bombing of all cities, an overwhelming majority would cry, "No, we will mete out to the Germans the measure, and more than the measure, they have meted out to us." The people of London with one voice would say to Hitler: "You have committed every crime under the sun. Where you have been the least resisted there you have been the most brutal. It was you who began the indiscriminate bombing. We remember Warsaw! In the first few days of the war. We remember Rotterdam. We have been newly reminded of your habits by the hideous massacre in Belgrade. We know too well the bestial assaults you're making upon the Russian people, to whom our hearts go out in their valiant struggle! We will have no truce or parley with you, or the grisly gang who work your wicked will! You do your worst! - and we will do our best! Perhaps it may be our turn soon. Perhaps it may be our turn now."
This memorandum and other actions of Churchill around the time of the Agadir made the prime minister, H. H. Asquith, realize that Churchill needed a more prominent government post from which to influence the nation’s strategic destiny. Within a few weeks of the resolution of the Agadir crisis, Asquith had elevated Churchill to First Lord of the Admiralty, in which office Churchill introduced a number of forward-looking reforms and innovations that echo down to the present day.
Important as these later speeches were, Churchill’s reputation as an orator still largely rests on the ones he gave during the war’s early years. And that is where the trouble lies with this book. According to Toye, a ‘powerful myth’ envelops Churchill’s role in the war, one in which through his speeches alone he rallied the British people by making them ‘feel the same way’ or by putting ‘into words what they were all feeling but could not express themselves’. This myth, he explains, is ‘crucial’, not least when it comes to the ‘popular image of the summer of 1940'. In fact, says Toye, historians would have us believe that whenever Churchill spoke ‘people were reduced to a condition of helpless ecstasy every time he opened his mouth’ (p. 3–4, 227–8).

It is said that immediately after giving the speech, Churchill muttered to a colleague, "And we’ll fight them with the butt ends of broken beer bottles because that's bloody well all we've got!"[14] Nonetheless, Churchill impressed his listeners and the speech was immediately recognised to be historic. One of Churchill's secretaries noted in his diary "A magnificent oration, which obviously moved the House".[15] A Conservative MP wrote in his diary "he was eloquent and oratorical and used magnificent English; several Labour members cried".[16] A Labour MP, Josiah Wedgwood, 1st Baron Wedgwood, friend and admirer of Churchill since the Dardanelles campaign, wrote to him, "My dear Winston. That was worth 1,000 guns and the speeches of 1,000 years".[17]

The electoral onslaught shook Labour but left them still in office. It took what Churchill called “one more heave” to defeat them in a second election, in October 1951. Churchill again took a vigorous lead in the campaign. He pressed the government particularly hard on its handling of the crisis caused by Iran’s nationalization of British oil companies and in return had to withstand charges of warmongering. The Conservatives were returned with a narrow majority of 17, and Churchill became prime minister for the second time. He formed a government in which the more liberal Conservatives predominated, though the Liberal Party itself declined Churchill’s suggestion of office. A prominent figure in the government was R.A. Butler, the progressive-minded chancellor of the Exchequer. Anthony Eden was foreign secretary. Some notable Churchillians were included, among them Lord Cherwell, who, as paymaster general, was principal scientific adviser with special responsibilities for atomic research and development.
I really wish we had leaders like this in our time. Churchill lead England through a brutal period of a year and a half when nobody was standing against Hitler in Europe. He never sugar coated things. He believed absolutely in what he had to do, and more importantly, he explained things clearly to people and made them understand that he needed them. Just check out his speechs during the Battle of Britain. He drives you with his words, spurring his listeners to action. 

This speech may be regarded as the most important Churchill delivered as Leader of the Opposition. It contains certain phrases - “the special relationship,” “the sinews of peace “ - which at once entered into general use, and which have survived. But it is the passage on “the iron curtain” which attracted immediate international attention, and had incalculable impact upon public opinion in the United States and in Western Europe. This speech ultimately defined the parameters of the Cold War.
While shaving one morning in 1953, Churchill remarked to John Colville, “Today is the 24th of January. It’s the day my father died. It’s the day I shall die, too.” He repeated this prediction to his son-in-law Christopher Soames shortly after his ninetieth birthday, in 1964. A few weeks later, on January 10, 1965, Churchill lapsed into a coma. Earlier that evening, during the nightly ritual of brandy and cigars, he had said to Soames, “It has been a grand journey, well worth making.” He paused and added, “once.”
