You seem to blend the Battle of Britain with all of WW2. In any case if let us say America did not enter the war - Germany would still not have invaded the UK even if the UK lost her empire (which by the way Hitler did not want to end) and thus the British people - including Scotland "would not be speaking German" as teh above poster claimed.
No I haven't. A cousin was killed flying Spitfires. Your revisionism forces one to unearth ghosts that should stay burried. Just leave it all alone.
