Have the drones met their Waterloo?

The botched drone strike on the North Waziristan-Afghanistan border which killed 40 people, apparently mostly tribal elders and police, may be the last straw. The Pakistan army chief of staff called it "intolerable," which is about as strong as this kind of official reaction gets. The strike came not that long after another Pakistani general made a somewhat bizarre statement praising the drones. Chances are the subtext of that statement was "we don't have to take military action in N. Waziristan because the drones are doing it all." Well, they're doing it all right; there's just one little problem: they don't always kill the "right" people.
