According to the BBC:
"[T[he speech setting out changes in Mr Bush's Iraq policy is likely to come in the middle of next week.
"Its central theme will be sacrifice.
"The speech, the BBC has been told, involves increasing troop numbers.
"The exact mission of the extra troops in Iraq is still under discussion, according to officials, but it is likely to focus on providing security rather than training Iraqi forces." [Note: This focus is necessary in order to avoid following the Iraq Study Group's recommendations.]
Silly me, I had always thought that you set objectives first, then decide what resources are needed to accomplish them.
