Obviously the memo shouldn't have been leaked.
But it certaily illustrates that Rumsfeld had good ideas and it's really too bad he was made to resign.
Here is a good advice from the Rummy memo:
"Stop rewarding bad behavior, as was done in Fallujah when they pushed in reconstruction funds, and start rewarding good behavior. Put our reconstruction efforts in those parts of Iraq that are behaving, and invest and create havens of opportunity to reward them for their good behavior. As the old saying goes, “If you want more of something, reward it; if you want less of something, penalize it.” No more reconstruction assistance in areas where there is violence. "
And I'm guessing that the people currently rewarding bad behavior with reconstruction funds are all at the State Dept. This memo could almost be summarized thusly: "Stop doing things the State Dept. way in Iraq!"
