This book offers a deep insight into Franklin D. Roosevelt's strategy to lure Adolf Hitler into declaring war on America in order to defeat Germany militarily and thus prevent the Nazis from developing the atomic bomb. At the end of 1939, President Roosevelt learned that Hitler was attempting to develop an atomic bomb against the United States. The president responded by tasking his own scientific community with developing an atomic bomb and forging plans for war against Germany. However, he was hampered by public opinion, as 80 percent of the American population was opposed to the United States becoming involved in another ground war in Europe. Roosevelt seized an opportunity in 1940 when Japan and Germany formed a military alliance. To lure Germany into the war, F. D. Roosevelt crippled Japan's war economy, prompting Tokyo to attack Pearl Harbor. A few days later, Hitler declared war on the United States. Based on declassified documents, this book shows that Pearl Harbor was not about Japan, but about the United States wanting to go to war against Germany. It reveals how the US Navy's intelligence system was able to crack virtually every Japanese naval code, but Admiral Husband E. Kimmel, commander of the US Pacific Fleet, was kept in the dark by his own government about the impending attack on Pearl Harbor.
