Strictly speaking, yes, I’ll concede that this changed the world if you are part of a military group and your foe is Israel or another highly advanced adversary. But no, I don’t think that this changes the world in the way that the article implies.
9/11 changed the world because it started two major wars in the Middle East, resulting in hundreds of thousands of deaths. It set the stage for world politics for the next few decades.
The reality of this attack is that it really won’t affect people’s lives in any meaningful way. Maybe a few people will be wary of using beepers for the next few months but I don’t see many people thinking of giving up their smartphones over this. Or perhaps I’m wrong and this foreshadows many similar supply chain bomb attacks in the future… I don’t know, but neither does Bruce Schneier and it’s too early to say definitively what the effect of this will be.
