The document summarizes key events leading up to and during the US entry into World War 2, including Japan building an empire through militarism and invading China in the 1930s, straining relations with the US. In 1941, the US froze Japanese assets and embargoed oil and scrap metal exports to Japan, making war inevitable. On December 7, 1941, Japan launched a surprise attack on the US naval base at Pearl Harbor in Hawaii using aircraft carriers, severely damaging the US Pacific fleet and bringing the US into World War 2.
