Makatak,
You have a few facts/timelines wrong in your critique.
The "USAR BCT" you mention was 2/28 ID, PAARNG, not USAR. They were the previous rotation to 1/1 AD (the unit owning AO Topeka in the book) in 2005-2006, not 2004. 2/2 ID, an active BCT from Korea, owned Ramadi 2004-2005. They did have a rough rotation due to a number of factors.
The western fight was under LtCol Alford in Al Qaim, yes his superb efforts to enlist the tribes in that area preceded 1/1's efforts and achieved some great local results. However, his actions had little influence in what transpired Ramadi 2006.
Jim Michaels, the author, covers all this in his book. (I read an early draft) While not an exhaustive academic history, he reveals a lot of the debates and discussions between MNF/MNC-I, I and II MEF, and the various BCTs about how to best do what you describe. Jim describes the overall effort to win the tribes in the Ramadi AO and gain the alliance with Sheik Sittar, who became the most important figure in the Awakening movement until his assassination.
As far as causation, the US's role in it, and other factors, that ground has been covered and re-covered here on SWJ. Reasonable people may disagree on how much one factor weighed vs. others, and we need a lot more interviews with Iraqis and perspective from time to make an accurate judgment. Timing was certainly a factor, and the situation in early 2006 provided opportunities not available in 2004-2005. However, I am firm in my opinion that our change of tactics played a significant role in starting, facilitating, and accelerating the awakening.
Jim's book, told largely from the perspectives of the major players of the US side in Ramadi, details how that was done. Jim's book does a great job capturing that story, and the essence of what the Soldiers, Marines, Sailors, and Airmen of the Ready First Combat Team paid for in blood in 2006-2007.
