President Roosevelt called it "a day which will live in infamy."
British Prime Minister Winston Church, who had been leading Britain in a fight for its life for two years, later reflected:
"No American will think it wrong of me if I proclaim that to have the United States at our side was to me the greatest joy. I could not foretell the course of events. I do not pretend to have measure accurately the martial might of Japan, but at thes very money I knew the United States was in the war, up to the neck and in to the death."
"So we had won after all!
"I went tot bed and slept the sleep of the saved and thankful."
