Re post #28, even if the US wasn't able to stop Hitler from capturing Britain, there would have been several alternative ways to get to Germany, perhaps through Italy and the South, but it would been have bloody with maximum casulaties. And we had bases in Iceland and possibly Ireland if we chose to attack Germany from the air in that direction as well. I'm not sure how useful the B-36 by itself would have been, the US still needed bases in Europe to attack Hitler directly.
