What if after waiting too long, Hitler finally realizes that the Kursk salient is too well fortified and allow for a strategic withdrawal instead? Basically, he lets the Russians waste resources constructing a fortified salient that never gets used. Instead, this disjoints the Soviet counter offensives, allows Germany to maintain the rebuilt Panzerwaffe and make Guderian happy all at once. Basically it is kind of like the 1917 withdrawal to the Hindenburg line and allows Germany to go on the strategic defensive under favorable circumstances.
However, it also gives the Soviets a pass and their Tanks Corps are not chewed up in the historical battles that revolved around Zitadelle.
At the same time, German forces are not as attrited, which they cannot afford like the Soviets could.
Forgetting this was totally against the nature of Hitler, does this allow Germany to slow the Soviet offensives that are coming and possibly to force a stalemate?
