I just thought that as Hitler since August 1941 wanted the Russian industrial territory to win the war,and as he did take up to 60% of Russian industry area, then as hindsight, was he wrong doing this or not? Getting these areas did not win him the war. The Russians still managed to make huge amounts of tanks and weaponry without these areas, and won the war.
What should Hitler have changed about his thinking? Flexible defence? Leningrad? Moscow?
