Hey totenkopf there are a lot of what if, many which were not possible, such the "Russian threat gone" why is it gone?, The American invasion? the Germans were in no way fit enough for the invasion of Britain let alone a transatlantic crossing. where would they stage there invasion from?

Since we have discussed most of the what ifs you have posted before, I will leave them, however I will answer the BRitish evacuation one.

The British would not have been in any shape to evacuate their airforce or there army, just look at the British evacuation of France, they had to enlist the help of the merchant navy, small tugs and every vessel that was capable of crossing the channel. How would they get the planes and men onto enough ships capable of transporting enough of these to canada, with enough escorts to hold back the probable german intervention of this evacuation? I would say the majority of the RN would be evacuated to somewhere like either, Canada or into the meditarrein. Althouhg with the the lost of the British Isle's the evacuation of North Africa would probably follow.
