What ISIS really wants. If you were afraid before, this ain’t going to make you feel better. We are fighting an implacable foe that we will have to kill. Forget any notion of proportional response (which has always and will always be an idiotic notion; in war, murder the enemy); forget hand wringing about the deaths of innocents because it can’t and won’t be avoided. There will be no negotiations, no trying to understand what they want, what might appease them. This is a clash of religions and cultures. We will win or they will win. And anyone who would take nuclear weapons off the table is a fool.
