Underground battles
<DEBKAfile's war diary for April 5th describes the battle for the underground facilities in Baghdad and elsewhere.
While of course (it IS DEBKAfile, after all) I have no confirmation that any of this is actually happening, the scenario described is highly plausible, and if we are not actually doing any of this already, we will have to do it soon.
The biggest battles of this war will be fought in the tunnels under Baghdad and elsewhere. And there it will be won. When the details of these battles come out in weeks or months, they will be amazing.
