The American public did not share his sense of urgency. The European War seemed far away. The American public blamed the Europeans for their war. China, while forgotten during the invasion of Poland, the Fall of France, and the Battle of Britain, seemed to most Americans to be the war America should fight, if America had to fight at all.
The heady days of December 7-10, 1941, with the Japanese advancing successfully along the entire front, must have been sorely trying on Roosevelt. The American public was incensed by the bombing of Pearl Harbor, which was seen as a treacherous, even cowardly, first strike against an unprepared America. While Roosevelt would be forever accused of allowing the attack to happen, in December 1941 the American public united against Japan in a way that the week before seemed impossible.
For Roosevelt, it was the wrong war at the wrong time. While Churchill reveled in the American entry into the war, saying "so we had won after all," he was making an assumption that most Americans were not - that the United States would be fighting against Germany. If in 1941, Roosevelt had gone to Congress with a declaration of war against Germany when the Japanese were winning everywhere, he would have lost crucial congressional support, perhaps even hounded out of office.
Hitler provided the answer. Like Churchill, he knew this was victory, an Axis one. On December 11, 1941, he declared war against the United States. His U-boats attacked American shipping from the Caribbean to Iceland, sinking many ships in the new "happy time" for German submariners.
Even with the German declaration, Roosevelt found himself unable to honor his agreements with Churchill to defeat Germany first. The precarious position of Allied forces meant that most of the men and materiel had to go to the Pacific. US Navy Commander-in-Chief, Admiral Ernest King, was a constant advocate for the Pacific Operations, while Army Chief of Staff George C. Marshall agreed with Roosevelt that Germany was the greatest threat.
For the first year of the war, the Pacific received most of the men and ships and tanks and planes that were trickling off of America's growing assembly lines. Especially after November 1942 (the Torch landings in North Africa) more and more of America's war potential was being sent to Europe. Army General Douglas MacArthur, Vice Admiral William Halsey and Admiral Chester Nimitz complained, and requisitioned more men and more equipment for the Pacific Theatre of Operations, but were consistently told to make due.
What no one could imagine in 1942 was that the Americans would revolutionize the concept of total war. Before Pearl Harbor, Roosevelt had secretly ordered members of his staff to convert America to a war footing in 1939. Marshall had developed a draft plan that would convert a highly motivated civilian population into a armed force of twelve million and enough materiel to equip 2000 divisions.
By June 1944, while the United States was able to support the Normandy landings and just one month later operations in Southern France, another entire amphibious operation was ongoing in the Marianas. While the Japanese could build only two fleet carriers and seven smaller carriers, the United States built over 100 carriers of all types during the war, and over 100,000 aircraft.
Unlike the Axis Powers, the United States and Great Britain went to total war mobilization immediately upon the start of hostilities. The American workforce, idle or unemployed since the Great Depression, mobilized everyone, including African Americans, women, and students. Also unlike the Axis, they did not have to initiate compulsory service in industrial plants, although the social stigma of not supporting the war amounted to compulsory service.
Men not in uniform were questioned on the street. Although rationing was enforced, most items except gasoline were readily available. Since cars were not made from 1942-1945, gasoline was not missed as much as it could have been. One nurse recounted decades later how ice cream was available in every New York restaurant, even though it was impossible to find in England were she had been stationed.
The sense of unity and comradeship was a sustaining factor throughout the war. With little consumer goods and large salaries, War Bonds and movies were the few items that everyone purchased. This savings would sustain the postwar boom in the United States until the 1980's, when another military buildup would be accomplished without war bonds and turn the world's largest creditor into the world's largest debtor. The American public held the notion of a postwar world as a time when the industry would shift from military production to consumer production. Privately, the economists feared another worldwide recession after the war, but that never materialized.
