Turning once again, and this time more generally, to the question of invasion, I would observe that there has never been a period in all these long centuries of which we boast when an absolute guarantee against invasion, still less against serious raids, could have been given to our people. In the days of Napoleon the same wind which would have carried his transports across the Channel might have driven away the blockading fleet. There was always the chance, and it is that chance which has excited and befooled the imaginations of many Continental tyrants. Many are the tales that are told. We are assured that novel methods will be adopted, and when we see the originality of malice, the ingenuity of aggression, which our enemy displays, we may certainly prepare ourselves for every kind of novel stratagem and every kind of brutal and treacherous maneuver. I think that no idea is so outlandish that it should not be considered and viewed with a searching, but at the same time, I hope, with a steady eye. We must never forget the solid assurances of sea power and those which belong to air power if it can be locally exercised.
On March 4, Churchill joined the presidential party aboard the Ferdinand Magellan (the train specially built in 1939 to accommodate presidential security and Roosevelt’s wheelchair) at Washington’s Union Station. When Truman noticed Churchill studying the presidential seal on the train, he proudly pointed out a change he had made to the seal—the eagle now turned to face the olive branch instead of the arrows. Churchill knew that his speech the next day might dissipate some of the rosy glow of the immediate postwar peace and he could not quite give the new seal his full approval. He asked the president, “Why not put the eagle’s neck on a swivel so that it could turn to the right or left as the occasion presented itself?”
The world looks with some awe upon a man who appears unconcernedly indifferent to home, money, comfort, rank, or even power and fame. The world feels not without a certain apprehension, that here is some one outside its jurisdiction; someone before whom its allurements may be spread in vain; some one strangely enfranchised, untamed, untrammelled by convention, moving independent of the ordinary currents of human action.
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.
