Step-by-step explanation:
The best supported inference about Roosevelt's point of view in his speech about the attack on Pearl Harbor is option a) He is angry at Japan for deceiving the United States and attacking without warning.
Throughout his speech, Roosevelt used strong and emotional language to convey his anger and condemnation towards Japan. He referred to the attack as a "date which will live in infamy" and highlighted the calculated and secret nature of the attack. This suggests that he was deeply angered by Japan's actions.
Roosevelt's primary focus in the speech, however, was not on revenge or taking immediate military action. He wanted Congress to declare war against Japan to ensure that as few American lives as possible are lost in the counterattack. He emphasized the need to defend the nation and ensure the safety of its citizens.
