What events and developments between 1945 and 1952 generated massive anxieties and challenges to American postwar confidence despite the country's record economic prosperity

Most of the anxieties during the period between 1945 and 1952 are related to communism, the Soviet Union, and the Cold War.

Explanation:

After World War II, two countries dominated world affairs: The United States, which favored capitalism and a market economy, and the Soviet Union, which favored communism, and a planned economy. These two countries had been allies during World War II, but once the war ended, they became enemies.

The U.S. had spectacular economic growth during the 1940s and 1950s, however, the Soviet Union also progressed, and it managed to detonate its own atomic bomb in 1949. This caused great anxiety in the U.S. because it meant that the enemy now had a lethal weapon that could cause deadly damage.

Another anxiety factor was the first proxy war between the Soviet Union and the United States: the Korean War, which lasted from 1950 to 1953.

during the debate over his landmark energy policy proposal, president jimmy carter failed to consult one of the most powerful senators, louisiana’s russell long, who would have a big say over whether the legislation moved through the upper chamber. this was classic carter. with a strong distaste for congressional politics, the president simply refused to do what most other presidents would consider routine, such as courting key senators. long became so irate with the president that when he was finally invited to a white house dinner, he stood up to ask a question and, before doing so, proceeded to sarcastically introduce himself: “i’m russell long, chairman of the senate finance committee.”

this interaction is a revealing moment in stuart e. eizenstat’s fascinating new history of carter’s presidency. the former peanut farmer from georgia was a president who, according to conventional wisdom, didn’t care much for party politics; nonetheless, in eizenstat’s view, carter’s legacy on domestic and foreign policy has been vastly underappreciated. the author paints carter as a “bold and determined” leader who bravely attacked the challenges of his time. eizenstat goes so far as to argue that carter might very well be the most successful one-term president in american history.
