Is that what “terrorism” is? “When multiple (explosive) devices go off”? If so, that encompasses a great many things, including what the US does in the world on a very regular basis. Of course, the quest to know whether this was “terrorism” is really code for: “was this done by Muslims”? That’s because, in US political discourse, “terrorism” has no real meaning other than: violence perpetrated by Muslims against the west. The reason there was such confusion and uncertainty about whether this was “terrorism” is because there is no clear and consistently applied definition of the term. At this point, it’s little more than a term of emotionally manipulative propaganda. That’s been proven over and over, and it was again yesterday.
