Today's The Australian has a highly revealing interview with SAS man Pete Tinley, who played a key role in operations in Iraq.

We were looking from just west of Baghdad all the way through to the Jordanian border and between the Syrian and Saudi borders.

It was all shadows and inferenced conversations between Iraqis. "
