Answer:
Winston Churchill was cautious with the Soviet Union. He acknowledged the enormous help that the Soviet Union had provided in defeating the Nazis, without which it would have been impossible to do so, and also thought that after such a brutal war, in which more than 20 million soviet citizens died, the thing that the Soviet Union desired the least was a new one.
However, he felt that the Soviet Union wanted to use the fruits of the war for its geopolitical advantage, by taking control of the occupied territories in Eastern Union. This is why Churchill said that an Iron Curtain was falling over Europe, that would divide the continent in years to come, in a capitalist-oriented Western Europe, allied with the U.S., and a socialist-oriented Eastern Europe, under the control of the Soviet Union.
