The Soviet Threat according to NSC 68
The design, therefore, calls for the complete subversion or forcible destruction of the machinery of government and structure of society in the countries of the non-Soviet world and their replacement by an apparatus and structure subservient to and controlled from the Kremlin. To that end Soviet efforts are now directed toward the domination of the Eurasian land mass. The United States, as the principal center of power in the non-Soviet world and the bulwark of opposition to Soviet expansion, is the principal enemy whose integrity and vitality must be subverted or destroyed by one means or another if the Kremlin is to achieve its fundamental design.
The antipathy of slavery to freedom explains the iron curtain, the isolation, the autarchy of the society whose end is absolute power. The existence and persistence of the idea of freedom is a permanent and continuous threat to the foundation of the slave society; and it therefore regards as intolerable the long continued existence of freedom in the world. What is new, what makes the continuing crisis, is the polarization of power which now inescapably confronts the slave society with the free.
The assault on free institutions is world-wide now, and in the context of the present polarization of power a defeat of free institutions anywhere is a defeat everywhere. The shock we sustained in the destruction of Czechoslovakia was not in the measure of Czechoslovakia's material importance to us. In a material sense, her capabilities were already at Soviet disposal. But when the integrity of Czechoslovak institutions was destroyed, it was in the intangible scale of values that we registered a loss more damaging than the material loss we had already suffered.
Thus unwillingly our free society finds itself mortally challenged by the Soviet system. No other value system is so wholly irreconcilable with ours, so implacable in its purpose to destroy ours, so capable of turning to its own uses the most dangerous and divisive trends in our own society, no other so skillfully and powerfully evokes the elements of irrationality in human nature everywhere, and no other has the support of a great and growing center of military power.
In summary, we must, by means of a rapid and sustained build-up of the political, economic, and military strength of the free world, and by means of an affirmative program intended to wrest the initiative from the Soviet Union, confront it with convincing evidence of the determination and ability of the free world to frustrate the Kremlin design of a world dominated by its will. Such evidence is the only means short of war which eventually may force the Kremlin to abandon its present course of action and to negotiate acceptable agreements on issues of major importance.
The whole success of the proposed program hangs ultimately on recognition by this Government, the American people, and all free peoples, that the cold war is in fact a real war in which the survival of the free world is at stake. Essential prerequisites to success are consultations with Congressional leaders designed to make the program the object of non-partisan legislative support, and a presentation to the public of a full explanation of the facts and implications of the present international situation. The prosecution of the program will require of us all the ingenuity, sacrifice, and unity demanded by the vital importance of the issue and the tenacity to persevere until our national objectives have been attained.
