Terror attacks are rare in the US because we've kept the terrorists out.
Because the United States is hard to attack. It's surrounded by the world's largest oceans and two large, friendly nations.
Now there's a concerted effort to ship terrorists to the western world.
Oh, do go fuck yourself, racist Western Exceptionalist. It's not Muslims invading, overthrowing and bombing countries on the other side of the planet from them for bullshit reasons- that's what you are doing to them. And all the 'Islamic terrorism' you can wank on about is either:
1) Directly sponsored by the United States, as when it funds and arms ISIS and Al Queda in Syria or Yemen
2) Blowback from your imperalistic shitbaggery. Want to know how to create a 'terrorist' in one simple step? You take a man who's done nothing to you and murder his family with a drone strike or a regime change.
