Conversely, there could actually be less pressure on Bomber Command to conduct those raids compared to OTL.
in OTL, the RAF, and bomber command specifically, were seen as the only real way Britain could take the war to Germany, and with the losses in France and Greece, the failures against the Germans in North Africa and the loss of Singapore and Malaya, they had to be seen to be doing something to hurt the Germans, otherwise America might start thinking that they weren’t worth supporting, and fearing a Russian capitulation if they thought Britain wasn’t willing to support them against the Nazi’s (also why Britain supplied so much equipment/resources to Russia, when they needed them themselves
so OTL was very much “we have to do something. RAF is the only effective weapon we have. Let’s throw everything into that.”
whereas ITTL, Britain is in a much stronger position. North Africa has been secured, Malaya held and the Japanese pushed back, and even losses such as France, Greece and Norway are not really classed as losses, due to the damage inflicted on the Germans and were mainly lost through factors outside British control (France collapsing etc). Plus the equipment Britain is supplying Russia with through lend-lease is far superior to that which was supplied OTL.
so overall, I think there will be less pressure/more ability to resist said pressure, on the British to conduct things like the 1000 bomber raids
