Other than a questionable metaphor in respect of associating a commercial strategy with a real world conflict that costs lives....!? However to follow your metaphor - any military planner will state that any Plan doesn't survive first contact with the enemy; consequenlty flexibility and change are to be expected and should be 'planned' for. Once engaged if the challenge has been underestimated then the 'Executive' arm should take appropriate action to meet the challenge. If this means bringing in senior officers with appropriate field experience and strategic skills that were not part of the original deployment then that is surely the right thing to do? Finally changing the fundementals of a region is a long term play where the apparent impact will look poor in the short term but the long term result will be a new stronger and more stable environment with very positive future prospects for all concerned. The error is to underestimate at the outset the length of time these changes take. However it is the duty of the 'forces' to minimise the negative impact and hold true to the long term goals.
