Some historical questions run and run
The Putters debates in 1649 partly debated why they were there - ie the causes of the Civil War (1640s) and surprising to me, they didnt come up with answer.
But others are objective: Pearl Harbor occurred Dec 1941 and directly caused America's entry to WWII
The German conduct of the Battle of Britain seems a little like the first - bombing was switched from airfields to cities. Records show that both sides over estimated losses (by an equal factor of 3) but why this was done and why that date was chosen may never be known. It is quite possible that the Germans did not realised how critical the defences relied on radar, which at that time, apparently they did not have.
Actually, re-reading your question, I think you may be right. That bombing of Berlin caused chaos, as Goebbels had promised that B wd never be bombed.
BUT in the sixties, when the Germans were bad but had then become good, there was pressure to classify the Baedekker Raids as strategic.
