It will happen too. Either a few “ISIS” members will shoot up a mall , or get some Ebola infection and spread it. Or detonate a dirty bomb, maybe even a nuke in a major city.
The media will play it down as senseless, mindless, fanaticism. Sabres will rattle in DC, and nothing will really happen. Allowing it to continue.
Or they will claim it is a homegrown terrorist, and if we had just respected the Muslims more, it would never have happened.
