> The US response to WW2 took years. That's incorrect. 4 months before the Pearl Harbour, FDR instated the Supply Priorities and Allocation Board by executive order. The purpose of the Supply Priorities and Allocation Board was to coordinate the distribution of materials and commodities related to national defense and to assist the Office of Production Management (OPM) in carrying out their overlapping duties. On january 1942, merely 4 weeks after Pearl Harbour, FDR dissolved the SPAB and instated the War Production Board by executive order. The WPB directed conversion of industries from peacetime work to war needs, allocated scarce materials, established priorities in the distribution of materials and services, and prohibited nonessential production. It rationed such commodities as gasoline, heating oil, metals, rubber, paper and plastics. Moreover, the U.S. economy was already radically shifting before 1941. Between 1939 and 1941, unemployment feel from 17.2% to 9.9% and by 1942 it feel to 4.2%. There's also an implicit assumption in your statement: the U.S. not actively joining the War until june 1944. That's incorrect as well. The U.S. already actively engaged in the North African Campaign on 11 May 1942. Barely 6 months after Pearl Harbour. Pearl Harbour kicked off the Pacific Theatre right off the bat. In June of 1942 - 7 months after Pearl - the Japanese Navy was soundly defeated in the Battle of Midway by Admiral Nimitz. August 1942 - 8 months after Pearl - the U.S. took the offensive at Guadalcanal. Admiral Yamamoto, who led the Pearl attack, never believed Japan would be able to win from the United States in the first place. He believed it was a massive strategical mistake. He has conveyed his feelings: > "I can run wild for six months ... after that, I have no expectation of success". Which is exactly what happened. So, no, the involvement of the United States in World War II is anything but an example of a nation state being forced to wait until it has ramped it's economic output before it can act. https://en.wikipedia.org/wiki/War_Production_Board https://en.wikipedia.org/wiki/War_Production_Board https://en.wikipedia.org/wiki/United_States_home_front_during_World_War_II https://en.wikipedia.org/wiki/United_States_home_front_durin... https://en.wikipedia.org/wiki/North_African_campaign https://en.wikipedia.org/wiki/North_African_campaign https://en.wikipedia.org/wiki/Battle_of_Midway https://en.wikipedia.org/wiki/Battle_of_Midway https://en.wikipedia.org/wiki/Guadalcanal_campaign https://en.wikipedia.org/wiki/Guadalcanal_campaign https://en.wikipedia.org/wiki/Isoroku_Yamamoto%27s_sleeping_giant_quote https://en.wikipedia.org/wiki/Isoroku_Yamamoto%27s_sleeping_...
