“You know, we’re willing to sacrifice a lot for this campaign. But we’re not willing to be murdered for it,” Gen. Allen told CBS’ “60 Minutes” in a segment that aired on Sunday.

Gen. Allen told CBS Correspondent Lara Logan that the insider attacks will continue: “The enemy recognizes this is a vulnerability. You know, in Iraq, the signature weapon system that we hadn’t seen before was the IED. We had to adjust to that. Here, I think the signature attack that we’re beginning to see the — is going to be the insider attack.”

Allen also said “the vast majority” of Afghans are “with us in this.” He noted that a number of Afghans have been killed trying to save NATO forces from rogue Afghans.
