What part of this don't you understand?
"How"
If you have an answer, please forward it to Headquarters, MNF-I Baghdad, CENTCOM, or the U.S. Department of Defense.
It's a nice sounding vision, but there was no plan for it. The CPA totally botched the job, and the military had a lot of conflicting (or non-existant) orders on what it was supposed to be doing.
Are serious? What sort of an answer would you expect the president to give to this amazingly ambiguous question. Do you want him to lay out the training schedule the military uses in bringing the Iraqi military up to snuff? Do you want him to detail the exact mission parameters used by the soldiers patrolling Baghdad? As for the conflicting orders given to the military. Please cite them and include your sourcing.
