barretthunter: Well, although neither Churchill nor Roosevelt were being entirely honest, being practical politicians with quite a lot at stake, it was Japan's attack on Pearl Harbour and not the sinking of the Reuben James that brought the US into the war.
Well we are certainly getting off the topic of spanking here but I can't refrain from commenting. Although Roosevelt sympathized with England and would have liked to get the US involved there was considerable opposition to that in the US at that time. The US did not declare war on Germany. After the Japanese attacked Pearl Harbor Hitler, honoring his pact with Japan, declared war on the US.
If Hitler had not been so stupid as to do that it is quite possible that the US would have devoted all its resources to fighting a war in the Pacific and stayed out of Europe.
The prevailing attitude of the US public at the time would probably have been, "The Europeans have their war to fight and we have our war to fight."
Yes, that would've been quite possible. However, had Japan not attacked the United States, FDR would almost certainly have maneuvered the United States into the European war sometime during 1942. (The U.S. Navy was already effectively at war with the Kreigsmarine, which included the sinking of the REUBEN JAMES.)
Also, a couple days after the Pearl Harbor attack, FDR was purportedly working on an address to Congress asking for a declaration of war against Germany and Italy. (Whether Congress would've gone along with it is another matter, of course, but Hitler and Mussolini made the issue moot by declaring war upon the United States.)
There is conjecture that FDR deliberately left the U.S. Pacific Fleet (minus its aircraft carriers) at Pearl Harbor in a low state of alertness in order to entice the Japanese to attack it there, calculating that such an attack would be the quickest way to draw the United States into the conflict.
However, I would agree that Germany primarily lost its chance to win the European war in the fighting outside Moscow, immediately before the Pearl Harbor attack. American involvement in the European theater, along with Britain in the "Grand Alliance,' meant the difference between Soviet domination of only eastern Europe, as opposed to all of Europe, after the war's end... --C.K.
