Area bombing (especially at night) was a tactic invented by and used with considerable frequency by Bomber Command.
Bomber Command copied the tactic from the Luftwaffe, who invented it. They pioneered all the techniques the RAF adopted, radio navigation beams to guide pathfinders to the target, pathfinders dropping incendiaires to mark the target, the main force bombers dropping large numbers of blast bombs and incendiaries.
The 8th and 15th bombed by day at smaller targets.
And they also bombed larger targets by day.
The RAF frequently bombed large cities.
And they also bombed smaller targets.
It's equally valid to say "The RAF bombed lots of precise military targets in Europe, the USAAF frequently area bombed German cities".
That's as valid as what you are claiming, but like your claims, gives a distorted picture.
Now the key is, if the target is a whole city, then how could you miss. If the target is an itarget away from a city, then hitting the target is tougher. So bombs on small targets is what counts.
If this is just a way of comparing accuracy, the USSBS gave a good example, attacks on 3 large German oil refineries, totaling 30,000 tons (ie a fair sized sample)
The USAAF achieved very good results in perfect weather, getting just over 25% of it's bombs inside the plant fences, iirc. However, that dropped to less than 10% using radar bombing methods when weather or smoke obscured the targets.
The RAF, bombing at night, averaged over 15% of their bombs inside the plant fences.
The average for both the USAAF and RAF was 12.8%, ie the USAAF average was considerably lower than the RAF average. And that's using precisely the same measure of accuracy.
