Well, as a knower of all things America, I have to say if you wish to achieve this result, removing FDR and replacing him with someone imcompetent/Communist/Fascist would probably get you there, but that is not the only way. Another such way would be for a particularly audacious Germany taking out America before the US could do the same to the Krauts. A third way would be for Japan to avoid attacking Pearl Harbor, possibly among other things, leading to a Neutral US that would suffer from the GD while the Soviets claim all of Europe, establishing themselves as the overdog and eventually pummeling America into submission with either military force, or by letting its isolated self apart.
