I have little doubt that had not Germany declared war on America after the Japanese attack on Pearl Harbor, America would not have sent a single GI to help the British.
America joined the war to save her own ass.
Roosevelt was arming / training the US for the "European conflict" long before Pearl Harbor.
The US had already instituted the draft and was training hundreds of thousands of combat troops before Pearl.
Shipyards and military industries were expanding exponentially.
Not to mention the Lend-Lease Act that was providing aid to Britain and China before any hostilities arose.
Roosevelt and Churchill had already discussed and agreed upon a "Germany first" policy when war came, knowing that a showdown with the Axis partner Japan was imminent (due to the US-led embargo against them).
The idea of American unpreparedness for the war is mostly myth. We were going to war eventually. Pearl just accelerated the timetable and silenced most of the isolationist opposition to it.
