At the beginning of May 1948 US-ambassador in USSR W. B. Smith conveyed to chief of Soviet diplomacy V. Molotov a memorandum about American reservations concerning contemporary Soviet Policy. This action not only evokes a political replay from J. V. Stalin, but arouses a big interest from Leadership of Czechoslovak communist government in development of American-Soviet Relations. At the Initiative from Prague the Czechoslovak charge d´affaires in Washington Josef Hanc had written a series of eight memoranda, where he analyzed actual state of relations between USA and USSR. The texts of these memoranda are published as an annex to this article. In his documents Hanc concluded, that American diplomacy does not aspire to some solutions of basic problems between both states, but only to troubleshooting of some partial problems. It has been the last attempt at some objective analysis of relationship between the super-powers at the beginning of Cold War from Czechoslovak view.
