These raids are being carried out in advance of what is anticipated to be a major US offensive in the Marjah region of Helmand province, a Taliban stronghold where some 10,000 Marines have been deployed. The offensive is expected as early as the end of this week.
Ignorance should be painful.
You cannot win what is essentially a ground war from the air.
You can, however, manage to kill a lot of innocent people, and radicalize those left standing into the waiting arms of the insurgents.
This is precisely what is happening in the Af/Pak war.
