Turns out Rummy didn’t just fail to plan for postvictory Iraq; he actively refused to do so. From an interview with Brigadier General Mark Scheid, chief of the Logistics War Plans Division:

“The secretary of defense continued to push on us … that everything we write in our plan has to be the idea that we are going to go in, we’re going to take out the regime, and then we’re going to leave,” Scheid said. “We won’t stay.”

Scheid said the planners continued to try “to write what was called Phase 4,” or the piece of the plan that included post-invasion operations like occupation.

Even if the troops didn’t stay, “at least we have to plan for it,” Scheid said.

“I remember the secretary of defense saying that he would fire the next person that said that,” Scheid said. “We would not do planning for Phase 4 operations, which would require all those additional troops that people talk about today.

The Army knew better. Rummy ignored them. Look where we are.
