The document discusses US isolationism and Republican policies following WWI. Isolationism allowed the US to focus on domestic industry and agriculture, making the US economy boom and becoming one of the richest countries in the world. Republicans were elected promising normalcy after Wilson, and US isolationist policies made the country self-sufficient in raw materials through strong agriculture, technology, and industrial sectors like coal, steel, textiles and oil production. WWI also financially and politically benefited the US through exporting goods like guns, munitions and foodstuffs to France and Britain.
