 Roosevelt made no attempt to paper over the great damage that had been caused to the American armed forces, noting (without giving figures, as casualty reports were still being compiled) that "very many American lives have been lost" in the attack.However, he emphasized his confidence in the strength of the American people to face up to the challenge posed by Japan, citing the "unbounded determination of our people".He sought to re-assure the public that steps were being taken to ensure their safety, noting his own role as "Commander in Chief of the Army and Navy" (the United States Air Force was part of the United States Army at this time) and declaring that he had already "directed that all measures be taken for our defense".
