Many questions arise about the surge. Is the new strategy working? How long will it take to work? Will it stabilize Iraq enough so we can withdrawl? How many extra troops are there? How many more will Bush send?
Amongst all these questions, a few things are clear. The violence and deaths have not abated. The number of US troops deployed in Iraq are increasing, not decreasing as promised. (i.e. We'll stand down as they stand up.) And the rhethoric against Iran is getting more dangerous.
But what of the troops? Where are they going and why do they need more?
The deployment of additional US forces originally called for securing a troubled Al Anbar province and securing Baghdad. But now it appears that the extra forces are being sent to locations other than the original plan.
Diyala is directly between Baghdad and the Iranian border.
Troops from Al-Anbar are being redeployed to Baghdad.
The surge was originally touted to boost security in Al-Anbar and Baghdad, but IMHO, it appears that the troops are going to Baghdad and Diyala. This would mass troops to the East of Baghdad and in and around the city of Baghdad itself.
This positioning supports defensive operations against any major ground offensive operations originating from Iran. It also may serve as an attack position for counter offensive operations against any major ground offensive operations originating from Iran. Additionally, it can provide on a continual basis, supplemental security to the northern oil fields.
