Re: WWII
That may be so.
However, the RAF was pretty much on its knees at the time, facing a choice of either losing the farm to airfield bombing or pulling the fighter bases back north of London (and a handy distance from any invasion from a German perspective).
The germans made an official apology for their accidental bombing within the exclusion zone, but Churchill bombed Berlin anyway. You don't have to be a genius to work out that for the outcome of the Battle of Britain, the London Blitz was the best possible thing to happen for the British, short of the Lutwaffe deciding to stay at home en masse. I personally reckon that presented with the opportunity and knowing that both Hitler and Goering had so much by way of promises riding on it, Churchill took the obvious course of action.
Chain Home is another issue. Actually here, the radar installations were rarely targetted after an initial assault by Stukas. There are two reasons for this. Firstly, they're damned difficult to seriously damage with anything bar a dive-bomber as precision bombing is a must. The Stukas suffered horrendous losses in the initial raids and the dive-bomber variant of the Ju-88 was still some time away. Secondly, the Lutwaffe found that after those inital raids to knock out radar, their bomber formations were still attacked in numbers by RAF fighters. The Observer Corps were able to a do a sterling job advising of the position of Germn formations in real time. The trick the Luftwaffe missed was that radar gave *early* warning, allowing the fighters to get a break and rearm/refuel between raids, while still being up and ready in time to intercept the next raid. Thus the limited strength of RAF fighter command was able to function in a manner as effective as a fighter force of around three times the size running continuous patrols. This is why the Luftwaffe continually issued vast overestimations of the strength of Fighter Command.
