After World War II, the United States became a global leader. Former President Harry Truman gets much of the credit for that. His “Truman Doctrine” was the basis for U.S. foreign policy after WWII, promoting strength abroad, which protected the U.S. and its allies and promoted international partnerships. President Donald Trump’s doctrine of “America First” threatens to reverse this by reshaping America’s role in the world, potentially antagonizing allies and, some fear, making America less secure. This audio story looks at the history behind the Truman Doctrine and how events today could permanently shift America’s role in the world.
