There's some good Sunday reading on future of Iraq after Zarqawi.
The Demise of Abu Musab al-Zarqawi, which briefly describes how a Bedouin with no formal education by sheer force of character made himself the center of a terror network. ...
Iraq's Democratic Processes, by Kanan Makiya. Zarqawi had not yet died when this was written, but if his logic is right, then his analysis shouldn't have to change by much.
Now for the Bad News has Marc Ruel Gerecht arguing that Zarqawi's death will mislead America into thinking that good intel and thunderbolts can do the job.
A Plan for Victory in Iraq by Fred Kagan in its own way makes the argument that the US has been too reluctant to change the strategic focus of its efforts from Islamic terrorism to sectarian violence.
In A Shattering of Memes, Dan Darling notes that considering that if Abu Ayyub al-Masri succeeds Zarqawi, it will have established that Saddam and Al Qaeda were in fact connected before OIF.
