Not sure which of McCaffrey's writings you mean, I read a detailed piece by him some months ago. Good stuff, can't recall it in detail as of this moment.
Got a link?
I don't always agree with him, but I find his experience as both a general, and then a civilian trying to do that insane "Drug Czar" job interesting. His perspective is unique, and usually his suggestions adhere to the practical.
I concur that "out in 2008" has been a rational planning framework since about 2005, but the question is "early 2008 or late 2008?" Immense political implications to both domestically, and since the whole world watches our domestic game play, internationally as well.
A thought on Al Qeada, and the "Al Qaeda in Iraq" issue.
It was good for Al Qaeda that Zarqawi was so successful in Iraq, it wasn't good for Iraq. It was a disaster for the US. I am aware of multiple opportunities in the summer of 2004 when a strike similar to the strike that did him in, had him and one thing or another went wrong, and in a number of cases a "weapons tight" order was given. To say that killing him in 2004 would have saved hundreds, hell, thousands of Iraqi lives, a mosque in Sammara, and most likely advanced the successful dialogue and rapproachment with many Sunni factions is an understatement.
That it took two more years to actually "get him" is an immense defeat in the perception war, that the US is at War on Terror, and Terrorists, and will hunt them down and kill them with dispatch. The recruiting poster for the Al Q side can point to how well Osama has stayed at large, and how successful Mr Z was at destabalizing Iraq when the American intent was to stabilize Iraq.
Put in maritime terms, his "stability denial" mission was an immense success, as a lot of U Boat "sea denial" missions were successful in WW II.
