You really odn't need a "freedom loving" citizenry to have this work. What President Bush and Maliki need are 10-15 Brigades of "freedom loving" soldiers willing to kill the bad guys without quarter. Those 10-15 Brigades need leadership. So, the ate of Iraq may well rest in the hands of 200 men or so. I hope General Petraeus finds them.
Yes, Iraq needs some Republican Guard units as it were, who are effective and movtivated. They need a lot of those professional Sunni officers back in the saddle. I doubt such units exist, or are likely to exist, but yes, we must hope.
