The United States’ doctrine of “containment” has its roots in a lengthy telegram composed by George Kennan, stationed at the US embassy in Moscow in the mid-1940s. Published Foreign Affairs magazine in 1947 as “The Sources of Soviet Conduct,” Kennan’s missive focused on what he saw as the “political personality of Soviet power”—suspicious and obstinate, but also very patient.
“Of the original ideology [of Communism], nothing has been officially junked,” Kennan wrote:
“Belief is maintained in the basic badness of capitalism, in the inevitability of its destruction, in the obligation of the proletariat to assist in that destruction and to take power into its own hands. But stress has come to be laid primarily on those concepts which relate most specifically to the Soviet regime itself: to its position as the sole truly Socialist regime in a dark and misguided world, and to the relationships of power within it.
The first of these concepts is that of the innate antagonism between capitalism and Socialism. We have seen how deeply that concept has become imbedded in foundations of Soviet power. It has profound implications for Russia’s conduct as a member of international society. It means that there can never be on Moscow’s side an sincere assumption of a community of aims between the Soviet Union and powers which are regarded as capitalist. It must inevitably be assumed in Moscow that the aims of the capitalist world are antagonistic to the Soviet regime, and therefore to the interests of the peoples it controls. If the Soviet government occasionally sets it signature to documents which would indicate the contrary, this is to regarded as a tactical maneuver permissible in dealing with the enemy (who is without honor) and should be taken in the spirit of caveat emptor. Basically, the antagonism remains. It is postulated. And from it flow many of the phenomena which we find disturbing in the Kremlin’s conduct of foreign policy: the secretiveness, the lack of frankness, the duplicity, the wary suspiciousness, and the basic unfriendliness of purpose. These phenomena are there to stay, for the foreseeable future. There can be variations of degree and of emphasis. When there is something the Russians want from us, one or the other of these features of their policy may be thrust temporarily into the background; and when that happens there will always be Americans who will leap forward with gleeful announcements that “the Russians have changed,” and some who will even try to take credit for having brought about such “changes.” But we should not be misled by tactical maneuvers. These characteristics of Soviet policy, like the postulate from which they flow, are basic to the internal nature of Soviet power, and will be with us, whether in the foreground or the background, until the internal nature of Soviet power is changed.
This means we are going to continue for long time to find the Russians difficult to deal with. It does not mean that they should be considered as embarked upon a do-or-die program to overthrow our society by a given date. The theory of the inevitability of the eventual fall of capitalism has the fortunate connotation that there is no hurry about it. The forces of progress can take their time in preparing the final coup de grâce. meanwhile, what is vital is that the “Socialist fatherland” — that oasis of power which has already been won for Socialism in the person of the Soviet Union — should be cherished and defended by all good Communists at home and abroad, its fortunes promoted, its enemies badgered and confounded. The promotion of premature, “adventuristic” revolutionary projects abroad which might embarrass Soviet power in any way would be an inexcusable, even a counter-revolutionary act. The cause of Socialism is the support and promotion of Soviet power, as defined in Moscow.”
“In these circumstances,” Kennan continued, “it is clear that the main element of any United States policy toward the Soviet Union must be that of long-term, patient but firm and vigilant containment of Russian expansive tendencies.”
“It is important to note, however, that such a policy has nothing to do with outward histrionics: with threats or blustering or superfluous gestures of outward “toughness.” While the Kremlin is basically flexible in its reaction to political realities, it is by no means unamenable to considerations of prestige. Like almost any other government, it can be placed by tactless and threatening gestures in a position where it cannot afford to yield even though this might be dictated by its sense of realism. The Russian leaders are keen judges of human psychology, and as such they are highly conscious that loss of temper and of self-control is never a source of strength in political affairs. They are quick to exploit such evidences of weakness. For these reasons it is a sine qua non of successful dealing with Russia that the foreign government in question should remain at all times cool and collected and that its demands on Russian policy should be put forward in such a manner as to leave the way open for a compliance not too detrimental to Russian prestige.
In the light of the above, it will be clearly seen that the Soviet pressure against the free institutions of the western world is something that can be contained by the adroit and vigilant application of counter-force at a series of constantly shifting geographical and political points, corresponding to the shifts and maneuvers of Soviet policy, but which cannot be charmed or talked out of existence. The Russians look forward to a duel of infinite duration, and they see that already they have scored great successes. It must be borne in mind that there was a time when the Communist Party represented far more of a minority in the sphere of Russian national life than Soviet power today represents in the world community.”
Finally:
“It would be an exaggeration to say that American behavior unassisted and alone could exercise a power of life and death over the Communist movement and bring about the early fall of Soviet power in Russia. But the United States has it in its power to increase enormously the strains under which Soviet policy must operate, to force upon the Kremlin a far greater degree of moderation and circumspection than it has had to observe in recent years, and in this way to promote tendencies which must eventually find their outlet in either the breakup or the gradual mellowing of Soviet power. For no mystical, Messianic movement — and particularly not that of the Kremlin — can face frustration indefinitely without eventually adjusting itself in one way or another to the logic of that state of affairs.
Thus the decision will really fall in large measure in this country itself. The issue of Soviet-American relations is in essence a test of the overall worth of the United States as a nation among nations. To avoid destruction the United States need only measure up to its own best traditions and prove itself worthy of preservation as a great nation.
Surely, there was never a fairer test of national quality than this. In the light of these circumstances, the thoughtful observer of Russian-American relations will find no cause for complaint in the Kremlin’s challenge to American society. He will rather experience a certain gratitude to a Providence which, by providing the American people with this implacable challenge, has made their entire security as a nation dependent on their pulling themselves together and accepting the responsibilities of moral and political leadership that history plainly intended them to bear.”
