[IronDuke99]

A good deal of the Royal Australian and Royal New Zealand navies were actually not in their home waters in 1939-40, but supporting the RN in the Med and Atlantic, etc. Canadian troops were also in UK.

the lower losses of the JU87's were purely because they suffered such heavy losses in their early operations against Britain, that the German Air Force had to totally withdraw them from operations over and close to UK.

Also worth bearing in mind that the German Air Force in 1939-40, in common with most other air forces, was actually not all that good at sinking enemy warships that early in the war.(although they improved later on).

I am not all that convinced that Edward VIII was really all that pro German and, in any case, even in 1940 the views of a British King, were hardly all that important in political as opposed to propaganda terms.

Yes a UK without Churchill might, maybe, have made peace with Germany after the fall of France, if the German terms had been generous enough (ie, no loss of territory, no German troops on any British territory at home or overseas, no concessions to Italy, full exchange of prisoners, etc). However even such a peace would have seen UK continue to re-arm and, perhaps to Britain's advantage, might have enabled this to happen without British bankruptcy by 1942...
