But, there's also this,
The book also says that the U.S. troop "surge" of 2007, in which President Bush sent nearly 30,000 additional U.S. combat forces and support troops to Iraq, was not the primary factor behind the steep drop in violence there during the past 16 months.
John McCain has been branding "the surge" so long that I'm not sure the truth will penetrate, that it was the bribing of the Sunnis and shift by Sadr that brought down violence, but, Woodward is taken so unquestionably in Washington that McCain might actually have to answer questions.
(And this is the first "tease." He always drags it out for a week. This first tease is the one intended to get Washington talking. The next one is likely aimed at all of us.)
