How did the Berlin Airlift help achieve American goals in postwar Europe?

The Berlin Airlift helped achieve American goals in postwar
Europe by proving to the Soviet Union that the US would not back down on the issue of Berlin and
by pushing West Germany much more firmly towards alliance with Western Europe and the United
States.

In postwar Europe, the US wanted to prevent any expansion of
the Soviet bloc that existed in Eastern Europe. In order to do that, the US had to convince the
Soviets that they would defend Western Europe. The US also had to convince the countries of
Western Europe that an alliance with the US was in their best interests. The Berlin Airlift
helped with both of these things. It showed the Soviets just how determined the US was to resist
communist expansion. It also showed the West Germans that the US would stand up for them and help
them. This proved that there were benefits to alliance with the
US.

In these ways, the Berlin Airlift helped to achieve US goals in
postwar Europe.
