I've basically stopped paying much of any attention after both parties turned on this event. There is no finding the facts when both are using it for political purposes.The General's regret was that no order to initiate planning for a rescue was issued or received.
But your posting history does suggest you would criticize the administration regardless of what it did.
The KEY difference I've noticed between people who hated Bush was that when he did something they liked, they basically pretended it didn't happen and said nothing. People who hate Obama will criticize him when he does things they like and will find a way to criticize him on both sides of a position. No rescue? Criticize for not doing anything. Rescue? Criticize for risking lives on no intelligence.
