What language does roosevelt use to emphasize the unique circumstances surrounding the speech

He used vivid, emotional words throughout the speech.

President Franklin D. Roosevelt: Yesterday, December 7, 1941—a date which will live in infamy—the United States of America was suddenly and deliberately attacked by naval and air forces of the Empire of Japan.  The label “infamy” foreshadows the tone of the entire speech.

The central purpose of this speech was to promote a war against japan.  Roosevelt's speech had an immediate and long-lasting impact on American politics. Congress declared war on Japan, with only one Representative, Jeannette Rankin, voting against the declaration.

here are some major conflicts i found. maybe pick one and do more research on it. (cause i ain't writing 6 paragraphs)

in 1877, the nez perce war took place.

1881 - president james garfield was assassinated.

1882 - the chinese exclusion act was passed.

1883 - a decision in the civil rights cases legalized racial segregation in the united states.

1887 - the dawes act was passed.

1893 - the panic of 1893 took place. (what a creative name)

and there are probably other topics you can find if you just search up "united states timeline," or "conflicts in the 19th century for america."

then once you find a topic you like find out how it affected the people of america and what not. (sorry if this feels a bit short changed, history was and never will be one of my strong topics)
