First I'll take my grain of salt, this coming from News Weak. This anonymous 'senior military officer,' is he retired? Sick Willy appointee? In any way shape or form associated with U.S. armed services? If it comes from an MSM source it needs triple verification.
In the history of fighting against terrorist movements, this kind of strategy was almost always used when the terrorists were eventually defeated. When the terrorists won (which they have), it wasn't used.
