Hundreds of Hezbollah pagers explode across Lebanon in unprecedented attack (youtube.com)

hundreds of seriously wounded, some dead. Fairly indescriminate, right? They just set them off wherever the person happened to be, in markets and stores, etc. It seems they want attacks that can't be proven-traced to them, other they would use operatives.

Some commenters say that this is so embarrasing to Hezbollah, they have to respond, and it will cause an escalation, in a violent way, maybe a different way.
Hezbollah was using pagers to avoid Israel's well-understood ability to monitor smart devices.

Now everyone's going to think Israel might set off explosions in the market? What is the US definition of terrorism?
What is the purpose of this attack though? The damage is minimal, it will just cause Hezbollah to check their pagers for explosives, and it'll bring international condemnation.
