He justified the low level of support it had been possible to give to France since Dunkirk, and reported the successful evacuation of most of the supporting forces. He resisted pressure to purge the coalition of appeasers, or otherwise indulge in recrimination. He reviewed the forces still available to prevent or repel any attempted invasion,[b] summing up the review as follows:
An introduction by the president of the United States would afford Churchill a world stage—whatever the venue. Though the date of the address, March 5, 1946, was half a year away, the opportunity fueled his imagination. He may have been out of office, but he was still the world’s foremost political figure, a man whose words could still command attention in the world’s leading nation. The thought buoyed his spirit, as he resumed his role of Leader of the Opposition.
Regardless of the origin of the phrase in his Iron Curtain speech, Churchill had been looking ahead to this problem since early in the war. In 1970, the retired prime minister Harold Macmillan related to the thirty-year-old Winston Churchill II a conversation he had had with the young man’s grandfather in early 1942. “It was after a dinner hosted by General Eisenhower for the joint Anglo-American command in Algiers, and your grandfather asked me to come back to his room for a drink. ‘What type of man do you think Cromwell is?’ was his odd question to me.
When Hitler launched his sudden attack on the Soviet Union, Churchill’s response was swift and unequivocal. In a broadcast on June 22, 1941, while refusing to “unsay” any of his earlier criticisms of Communism, he insisted that “the Russian danger…is our danger” and pledged aid to the Russian people. Henceforth, it was his policy to construct a “grand alliance” incorporating the Soviet Union and the United States. But it took until May 1942 to negotiate a 20-year Anglo-Soviet pact of mutual assistance.
“Even though large tracts of Europe and many old and famous states have fallen or may fall into the grip of the Gestapo and all the odious apparatus of Nazi rule, 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.”
On June 18, 1940, immediately after the fall of France, Churchill rallied the British people once more. With his characteristic Shakespearean gusto, he declared, "Let us therefore brace ourselves to our duty, and so bear ourselves, that if the British Empire and its Commonwealth last for a thousand years, men will still say, 'This was their finest hour.' "
Nevertheless, our thankfulness at the escape of our Army and so many men, whose loved ones have passed through an agonizing week, must not blind us to the fact that what has happened in France and Belgium is a colossal military disaster. The French Army has been weakened, the Belgian Army has been lost, a large part of those fortified lines upon which so much faith had been reposed is gone, many valuable mining districts and factories have passed into the enemy’s possession, the whole of the Channel ports are in his hands, with all the tragic consequences that follow from that, and we must expect another blow to be struck almost immediately at us or at France. We are told that Herr Hitler has a plan for invading the British Isles. This has often been thought of before. When Napoleon lay at Boulogne for a year with his flat-bottomed boats and his Grand Army, he was told by someone. “There are bitter weeds in England.” There are certainly a great many more of them since the British Expeditionary Force returned.
