Lets not reserve the judgment for one, there is plenty of grief to go around and ALL are accountable.
People talk about "one voice" and the need for "Board unity" but it is difficult to reconcile the Generals well espoused views with the current situation UNLESS he was one of the ones to walk from that Board meeting. It is about personal integrity and given his long career I would not have thought some pittance of a directors fee would equal a lifetime of integrity building.
Most Directors I would suggest do it for the power and ego and that raises other issues as we have all seen other cases where ego was not matched by intellect.
