U.S.A.'s policy toward the U.S.S.R druing cold war

I'd like to write about the U.S.'s deplomacy during the era of cold war. Mainly, the policy toward the Union of Soviet Socialist Republics. Because, the cold war throw the world into confusion and we should not forget it. However, many Japanese students doesn't know the history. Especially, the students were born in after 90's. Nevertheless they should study it when they study international studies.
