If an identical attack happened in the United States tomorrow, there wouldn't be a person here who didn't think it was al Qaeda, simply becuase that's who we are accustomed to being attacked by. Even though it could be say Puerto Rican nationalists for example.

The same dynamic is likely at work in Spain. The notion that it could be Al Qaeda just seems absurdly remote on the surface.
