Fighting terror can be like Whack-a-Mole.
You take out one guy and another pops up somewhere else.
Even worse; some don't stay dead after you announce that they have assumed room temperature.
Take Hakimullah Mehsud for instance.
He was supposedly taken out months ago, and here he is with not one, but two new videos (maybe an album too).
That's just what happens when you think you can fight terror from 20 thousand feet.
