Winograd commission member - PM should have been removed from office

Yechezkel Dror, one of the members of the Winograd commission that investigated the Second Lebanon War had very harsh criticism for the political system in general, and specifically PM Olmert:

A Severe Verdict That Didn’t Go Far Enough

... As a member of the commission, I expected that the Cabinet would resign or be dismissed after the interim report appeared. Indeed, the chief of staff honorably resigned, and the minister of defense was made to leave. The prime minister, however, did not resign, nor was he forced to leave. I do not think this would have happened in any other parliamentary democracy.
...
In retrospect, I think I erred in trusting the political system and the public to do what was obviously required in light of our harsh findings, namely to remove the prime minister from office. I did not expect such dismal behavior motivated mainly by narrow party interests and personal career considerations on the part of many members of the Knesset (with some distinguished exceptions). I regret that I did not insist on making an explicit institutional recommendation that, because of his grand failures, the prime minister should not continue to serve, even if this might have been regarded by some as deviating from the legal limitations imposed on the commission. This recommendation is all the more urgent and valid in light of developments since publication of our final report.
