Bing West and the War in Iraq.
One of the things I find fascinating to watch is the progression of viewpoints of books on the Iraq War. There is a whole separate blog post here, but I can basically divide them into three categories:
1) We kicked Iraq's ass in less than three weeks (2003-2004)
2) The insurgency is going to bleed us dry (2005-2007)
3) We kicked the insurgents ass (2008-2010)
Retired Marine General Bing West has written three books on the Iraq War and all of them are excellent reads. They basically cover each of the periods, although they cover a wide span of time and topics.
Finally, his third book, The Strongest Tribe, is meant to be a mini-campaign history of the entire Iraq conflict after the initial invasion, and is told from more of an operational and strategic point of view. The time from April 2003 to fall 2006 goes by fairly quickly as West attempts to get into the nuts and bolts of the surge and the 2007 fighting. It is a quick read and an excellent overview of someone just beginning to read about America's conflict in Iraq.
All of these books are good reads, although I would recommend The Strongest Tribe the most as a basic primer of the Iraq War.
