answer this questions for me

George Kennan provided an analysis of Soviet intentions and capabilities early in the opening rounds of the Cold War.The National Security Council offered their own take on the looming dangers of the perceived threat of Soviet expansionism.Discuss their respective points of view and given that nearly three years separated their publications, it is clear that events between the two may have shaped policy decisions of the then current administration and future ones. Are there more similarities between the two or are there more dissimilarities?
