If you put enough pressure on an adversary group, or terris group to make it adapt, but not enough to destroy it, you actually improve that group. i use the example o sani taliban, where we have killed, at a distance of about four years apart, three successive leaders of the pagasani taliban. And each time that leader has been replaced by a better, more experienced, more respected, more capable, more ideologically extreme leader. So we're actually improving the terrorist as we do that. Another example is in a rack, where we almost completely destroyed arcida in a rack and all that was left were this very small remnant of highly experienced, extremely pissed off
