It's not a matter of treating the Iraqis as 'grown ups.' It's a matter of understanding the details of their unique situation, and not completely ignoring the fact that most of the problems there now are being caused by outside terrorists.
To believe that we should just leave them hanging out to dry is the result of naivte...........which is why the flaky left believes it.
(I can't come up with a reason that anyone claiming to be a conservative would come to the same conclusion).
Nor can I. Thanks ;*)
