How did the U.S. respond to the iron curtain?

In response to the Iron Curtain, which symbolized the division between the Soviet-controlled Eastern Europe and the West, the U.S. adopted a policy of containment aimed at preventing the spread of communism. This included the establishment of NATO in 1949, economic aid through the Marshall Plan to rebuild Western European economies, and support for anti-communist regimes globally. Additionally, the U.S. engaged in various military and diplomatic efforts during the Cold War to counter Soviet influence and promote democracy.
