You do realize that the RAF managed to stand its own vs. the Luftwaffe? The Luftwaffe continued to lose planes faster than the Brits by the end of that battle, and the Brits were outproducing the Luftwaffe at the time (I think). Not to mention that every German pilot shot down over Britain was doomed to POW status.

Also, if the strategic/terror bombing of Germany has any message behind it, it's that a populace can and does get used to bombing.

None of this, by the way, delays Pearl Harbor and the American entry into war.
