Just before, and in the early day of WWII, Germany put together a very sophisticated Civil Defense plan, that monitored night time raids by British bombers, alerted the civilian population to take shelter, and let the civilian population know when it was all clear, and it could exit the bomb shelters.
Only the Brits quickly found out that by sending a couple of bombers to Berlin, they could get the Germans to activate their civil defense system, interrupting night time business, and depriving millions of war workers of a night's sleep. The loss of productivity alone made the raid a success, even if the bombers never dropped a bomb within 10 miles of a target.
That reminds me that any bomb coming within a mile (or half a mile?) was scored as a direct hit.
