>>More specifically, Hitler tried to seize both Moscow and Leningrad.
So you agree that focus changed from the drive towards Moscow to other goals?
Without commenting on the poor understanding of Soviet capability that underlay Hitler's decisions or the staggering size/distances in the USSR that are not well understood in the Western world to this day, do you think things would have been different had the drive towards Moscow been maintained with the goal of decapitating government?
"... They ne'er cared for us
yet: suffer us to famish, and their store-houses
crammed with grain; make edicts for usury, to
support usurers; repeal daily any wholesome act
established against the rich, and provide more
piercing statutes daily, to chain up and restrain
the poor. If the wars eat us not up, they will; and
there's all the love they bear us."
-- Shakespeare: Coriolanus, Act 1, scene 1
