How was the US trade policy changed after world war 2?

After World War II, U.S. trade policy shifted towards promoting free trade and economic cooperation, moving away from the protectionist measures of the interwar period. The establishment of institutions like the General Agreement on Tariffs and Trade (GATT) aimed to reduce tariffs and facilitate international trade. Additionally, the U.S. implemented the Marshall Plan, which provided aid to rebuild European economies, further integrating global markets and fostering economic interdependence. This shift laid the groundwork for a more interconnected global economy in the following decades.
