THE SURGE IS A LIE
The most important thing, which for political reasons no one will mention, is that GENERAL CASEY WAS A SOCKPUPPET, a mouthpiece for the White House, not a good General, not a thinker, not smart, and generally WHOLLY INCOMPETENT to manage the war in Iraq. Commander-in-Chief kept him in charge for years.
General Petraeus isn't perfect, but he isn't stupid, and, from his position managing the Kurdish north, was able to look at what was going on in Iraq and fix some of the problems.
Why are we doing better in Iraq? Casey was incompetent, Petreaus is not. I finally saw someone say this last night. Well, Brian Lamb interviewed Linda Robinson, author of Tell Me How This Ends: General David Petraeus and the Search for a Way Out of Iraq
