This trend is most likely to continue by all indications.
The last that I heard, Jveritas was noting that the jihadi websites are calling for new recruits to go to Afghanistan/Pakistan...and to avoid Iraq.
They’ve conceded the field.
That being said, there are still going to be a few diehards doing very mean, nasty things to civilians and Americans in Iraq...just on a scale far smaller than in the past.
Which is to say, we’ve won Iraq. We know it. They know it.
