To deal with terrorists we are going to have to develop teams that deal in hard core tactics, with plausible deniability. I would not have said this a few years ago, but it is clear there is no reasoning with these Islamist fanatics. They would as soon blow us all up in one big mushroom cloud if they had the chance--time to start severing the heads of this many-headed snake around the world. And causing a lot of weeping and grieving in their sanctuaries. This is the only thing they know.
