Uh, first we're the ones that created these terrorist sects.  Al Qaeda was our work, as is ISIS.  Yanno, that whole "enemy of my enemy is my friend" garbage.  Had we not start meddling in their affairs to begin with, we wouldn't be the target.  Ever wonder why the countries who don't mess around in the middle east see pretty much nothing when it comes to these terrorist attacks?  Look around...

I'm much more worried about my fellow citizen killing me than the very rare terrorist attack we see here.  I'll let you look up those numbers.  Maybe it'll stick better than having someone you disagree with tell you the truth.
