"The Sources of Soviet Conduct" is the formal title for the article written by George F. Kennan under the pseudonym "X" and published in the July 1947 issue of Foreign Affairs magazine. The article expanded on Kennan's ideas on the impact of Soviet ideology, which he originally sent to the State Department in confidence as a response to the implications of a speech made by Joseph Stalin in February 1946. The version of the article in this folder is printed on small photograph paper.
