Final answer:
President Franklin D. Roosevelt's argument for war with Japan was primarily based on the surprise and unprovoked nature of the Pearl Harbor attack, leaving the US with no choice but to respond. He used his "Day of Infamy" speech to present this case to Congress and the American public, within the broader context of defending democracy and freedom against Axis powers.
Step-by-step explanation:
President Franklin D. Roosevelt developed his argument regarding war with Japan primarily by emphasizing that the actions of Japan had left the United States with no other choice, which aligns with option A. In his "Day of Infamy" speech, Roosevelt characterized the attack on Pearl Harbor as a secret and calculated act of aggression. He highlighted the unprovoked nature of the attack, suggesting that it was a breach of trust between nations, and used rhetorical strategies to align the United States with the moral high ground.
The context leading up to the Pearl Harbor attack, including the Japanese invasion of China and the resulting strains on US-Japanese relations under the Open Door policy, supported Roosevelt's case that the US was left with little recourse but to declare war. Additionally, the president outlined his role in protecting the nation and its interests from future attacks by Japan, while ultimately framing the conflict within the broader struggle for democracy and freedom against the Axis powers of Germany, Italy, and Japan.
