The thing is this is just going to a lead to sick, self-reinforcing loop of fuckery. ISIS et al. get bolder from being fueled off of Trump rhetoric and policy, stage more attacks. Trump convinces the public that "See? You need mytinyYUGE iron fist now more than ever!", enacts more draconian policies and threatens to/actually does attack the Middle East. ISIS et al. get bolder... etc..
It's fucked.
