_Those who compare the age in which their lot has fallen with a golden age which exists only in imagination, may talk of degeneracy and decay; but no man who is correctly informed as to the past, will be disposed to take a morose or desponding view of the present._ THOMAS BABINGTON MACAULAY [Illustration] Is the long story of British greatness nearly done? That is the question we must ask ourselves as we survey the real Britain, the changing Britain of today. The question is a vital one for Americans. Our generation faces a challenge that dwarfs those offered by Germany in 1917 or by Germany, Japan, and Italy in 1941. Communist dominion stretches from the Elbe to the Pacific, from the arctic to the jungles of Indochina. Nearly a thousand million people serve tyrannical systems of government. Behind the barbed wire and the empty-faced guards at the frontiers we can hear the explosions of devastating weapons of war, we can discern the ceaseless effort to achieve the world triumph of Communism. To the leaders of all these millions, the United States is the enemy, the people of America their principal obstacle in the march to world power. As the most successful capitalist state, the United States is now and will be in the future the principal target for the diplomatic intrigues, the political subversion, and the economic competition of the Communist bloc. The avenues of attack may be indirect, the means may differ from place to place. But the enmity does not vary. America is the enemy today, as it was yesterday, as it will be tomorrow. Living at the apex of power and prosperity, it is easy for Americans to be complacent, it is natural for them to fasten on hints of Russian friendship. But it is folly to believe that the world situation is improving because Nikita Khrushchev jests with correspondents in Moscow or because a delegation of visiting farmers from the Ukraine is made up of hearty extroverts. For the Communist challenge, as it has developed since the death of Stalin, is as real as that which produced the cold war of 1945-53. But because it is expressed in terms superficially less belligerent than blockades and riots, violent speeches and editorials, and overt instant and implacable opposition to Western policies, the current challenge is far more insidious. Concepts and policies developed to meet a purely military challenge will not suffice to defeat it.
