Answer:
In Europe.
Explanation:
There were stark disagreements. One major contentious issue was the fate of Germany in the postwar period. The Soviets opposed rebuilding Germany and the Marshall Plan. In 1948, Soviet top leader Stalin ordered the Berlin Blockade, which failed because of the air bridge organized by the US to supply West Berlin. The Truman administration and European governments did not trust the USSR intentions and feared aggressive moves to expand communism in Western Europe; Red Army contingents were stationed in Eastern Europe.
