Where conditions permitted, the Soviet rulers have stimulated and aided armed insurrection by communist-led revolutionary forces, as in Greece, Indo-China, the Philippines, and China, or outright aggression by one of their satellites, as in Korea. Where the forces of nationalism, independence, and economic change were at work throughout the great sweep of Asia and Africa, the communists tried to identify themselves with the cause of progress, tried to picture themselves as the friends of freedom and advancement--surely one of the most cynical efforts of which history offers record. Thus, everywhere in the free world, the communists seek to fish in troubled waters, to seize more countries, to enslave more millions of human souls. They were, and are, ready to ally themselves with any group, from the extreme left to the extreme right, that offers them an opportunity to advance their ends. Geography gives them a central position. They are both a European and an Asian power, with borders touching many of the most sensitive and vital areas in the free world around them. So situated, they can use their armies and their economic power to set up simultaneously a whole series of threats--or inducements--to such widely dispersed places as Western Germany, Iran, and Japan. These pressures and attractions can be sustained at will, or quickly shifted from place to place. Thus the communist rulers are moving, with implacable will, to create greater strength in their vast empire, and to create weakness and division in the free world, preparing for the time their false creed teaches them must come: the time when the whole world outside their sway will be so torn by strife and contradictions that it will be ripe for the communist plucking. This is the heart of the distorted Marxist interpretation of history. This is the glass through which Moscow and Peiping look out upon the world, the glass through which they see the rest of us. They seem really to believe that history is on their side. And they are trying to boost "history" along, at every opportunity, in every way they can. I have set forth here the nature of the communist menace confronting our Republic and the whole free world. This is the measure of the challenge we have faced since World War II--a challenge partly military and partly economic, partly moral and partly intellectual, confronting us at every level of human endeavor and all around the world. It has been and must be the free world's purpose not only to organize defenses against aggression and subversion, not only to build a structure of resistance and salvation for the community of nations outside the iron curtain, but in addition to give expression and opportunity to the forces of growth and progress in the free world, to so organize and unify the cooperative community of free men that we will not crumble but grow stronger over the years, and the Soviet empire, not the free world, will eventually have to change its ways or fall.
