The fact that the senior level of the IDF potentially planned this war incorrectly has nothing to do with a decline in the IDF leadership over time. It has more to do with Halutz having been appointed, not for strategic brilliance, but to be Sharon's yes-man on the disengagement. This was also part of a broader power struggle between Mofaz and the previous Chief of Staff, Yaalon. Also sacked was the well-regarded Head of Military Intelligence, replaced by Halutz's deputy from the Air Force. Another poor change at Northern Command sealed the deal. Thus, the present situation more likely stems from a poor crop of leading cronies. Had Sharon been around he might have bypassed Halutz and Co during this war, but Olmert has no such experience (nor does he have much skill in anything other than politics and corruption - e.g. he couldnt even arrange for Jerusalem trash collection as mayor there, making the current Haredi mayor appear a gift form God).
