Rumsfeld: Did He Underestimate The Intensity Of The Resistance? (Small – 2 MB)
Tim Russert:
“Did you underestimate the intensity of the resistance?”
Donald Rumsfeld:
“I don’t know. You know, I don’t know that we — you don’t sit down and make a calibration that the resistance will lead to X numbers of Iraqis being killed per week, or that so many coalition people being wounded per week. That isn’t the kind of calibration you make. What you do is you say, here’s what you have to do to prevail. You have got to get the sovereignty transferred over to the Iraqi people, you have got to get the essential services going, and the economy on a path upward. And you’ve got to get the security responsibility transferred to the Iraqi people. That’s — because it’s their country. We’re not going to provide security in their country over a sustained period of time.
So we’ve gone from zero to 100,000 Iraqis providing security in that country, and our plan calls for us to go over 200,000 by next year.”
