I tend to agree, and in addition, Hitler somehow managed to strike at the optimum moment, when the Red Army had reached rock bottom in readiness for war. Lack of trained officers, miserable supply situation, hardly any working tanks, dismantled frontier defences due border shift in Poland, lack of radios, etc. The Wehrmacht on the other hand was in top form. Had he waited even a year, things would have been quite a bit different with the advantage gap closing rapidly.

It's not really surprising the little corporal held his hunches in such a high esteem, up until mid-1942 he was mostly correct.
