Ah, Stalin, I'm pretty sure he's been given way more than his due already.
Dig deeper into the facts and beyond the propaganda. You make it seem like 14% of the Red Air Force's aircraft is a trivial and insignifigant number, similarly to the Red Air Force's emphasis and mentality through most of that time period on pilot training and survivability beyond one sortie. And the Siege of Leningrad, puh-lease, history has yet to give us better evidence and proof of what will happen in a modern battlefield when two idiots in command colide. Had either side been taking orders and been under the command of a dictator with anything but an egotisistical military strategy and agenda for Leningrad then they would of conducted that seige a lot better, in a lot less time, and with a lot less loss of life. Even the name of the battle itself has always erked and troubled me, it's considered a siege yet in my mind a siege is a strategical and planned operation involving esentialy to out-smart and out-wait your fortified and isolated opponent, rather than physicaly wrestle and force them into submition by brute force.
