I don’t mind saying, I’m writing a book, and this is one of the conversations near the end. One character says to another: “Yeah, things are better. But can any of us truly say that things wouldn’t have improved if that terrorist hadn’t threatened everyone?”

Thankfully, in the story’s case, the reply to that quote is that while explosions and deaths were far more visible, a variety of powerful people were already making broad changes - just in a slower and less risky way. Of course, that’s fiction; and is not saying those things are a guarantee in the real world.
