Did the resistance exist truely at that point? Also the group here which dealt with them SOE wasn't yet set up at that point was it?
Eitherway at that point it the war we were very much on the defensive and weren't in a position to put vital resources needed for the protection of the country into an offensive which would have cost us dearly in both men and machines. Just look at what happened later with the dam buster raid for instance. It was meant to cripple the industrial heart of germany, yet within weeks they were up and running again, but 617 squadron was decimated by that raid.
