What factors conspired to propel the United States to emerge as a military and economic powerhouse prior to World War II?
antiseptic1488 [7]

Answer:

Explanation:

Based on my research World War II took place between Sep 1, 1939 – Sep 2, 1945. During the 1930's (1929-1939) The <u>United States of America</u> was in the middle of the <u>great depression</u> after the stock markets crashed leading to worst economic crash in history. Therefore they were not a military or economic powerhouse at that point. Things started to change with WWII , when the government re-purposed factories to make war supplies thus giving millions of people jobs overnight and restoring the economy.
