There's a sense in which a lot of these terrorists have already lost. I mean, look at the lives they lead. They have to lie and skulk around in the shadows. They have to cook up and then swallow their own mindless propaganda. All that unites them is their own mad anger. They can't vote or run for office without risking capture. Some life.
There's a infinitesimally small chance that some international terrorist will kill or harm you personally. Conversely, there's an almost certain chance that the terrorist who wants to kill you wakes up on a filthy mattress surrounded by cockroaches and rats.
Fuck 'em.
At an individual level, get to know your neighbours, go to local council meetings. Reinforce your civilized society from the ground up. At the very least you'd be guaranteed success fighting those local punks who "terrorize" your elderly neighbours.
