To me, this means that your answer is “yes”, the Battle of Britain was fought for nothing. I disagree.
With skies cleared of RAF fighters, all UK cities would have been at the mercy of German bombers, even in daylight. I don’t dare to say that Churchill would have surrendered, but certainly he would have been forced to negotiate a compromise. And yes, this would have changed the course of the war.
My opinion, of course.
