After Steve Jobs returned to Apple early in 1997, and then became de facto CEO later that year, he was unquestionably a wartime CEO.
Yet many years after he'd successfully turned Apple around and, arguably, become a peacetime CEO, he wasn't fired. Moreover, were it not for his declining health, I don't think he would have stepped away even as Apple became the dominant force it's turned into over the last few years.
Maybe eventually he'd have stopped but, were he still alive, I imagine he'd still be leading Apple now.
He also said that he learned a lot in his time away from Apple, that he became less tyrannical in the interim. So there's a strong argument to be made that he learned to be a peacetime CEO during his time at Pixar et al.
