HThe wartime alliance
was based on aversion to a common enemy, not on philosophical
consensus or similarity of social system or way of life.
HAt the Potsdam
Conference Stalin offended the United States and Great Britain by making
demands they held to be in excess of the needs of Soviet
national security.
HDespite the animosity,
the Allies reached agreement on the general lines of the
occupation.
HWithin several years,
the Soviet Union violated many of these agreements.
