Perhaps...if he's dead or captured.
We haven't heard from Zarqawi since January. Al Qaeda's attacks have fallen each month since October.
These are *facts* that are not reconciled by a fully functioning terror leadership in Iraq.
On the other hand, if he is alive and uncaptured, then you've got to go with my theory that he's moved out of Iraq (probably to Southern Lebanon). Because being out of Iraq would likewise explain the above facts.
The April stats will tell me more...
