[ANDY-J1]

In terms of aircraft destroyed by far the majority of German planes and experienced pilots were lost in the air battles against allied bombers over the Reich. Also there is the effect of British strategic bombing against German industry. Both these factors made things a lot easier for the Russians as they lesssened the tanks and aircraft available for the eastern front so the British were contributing directly in aiding the Russians- imagine the carnage had the Germans been allowed to employ large numbers of jets in the east rather than have them squandered fighting off allied bombing raids. Also comparing numbers of divisions is not always useful- not all divisions were at full strength and the premier divisions of the German army 1st and 2nd SS Panzer, Panzer Lehr etc. (which were at full strength) were stationed in France to combat the allied landings. Another factor is the German rocket programe- that utilised a massive amount of resources that could have been used against Russia and it was the one German weapon that was intended for use solely against Britain, so simply by remaining in the war Britain forced the Germans to divert resources from the war in the east.
