The question now ringing through Israel is whether it helps win the war. There is broad agreement that the deadly sabotage of Hezbollah’s electronic communications was a short-term tactical success that sent its foe into disarray and incapacitated thousands of its fighters.

Israel bombed Hezbollah strongholds in southern Lebanon on Thursday, piling pressure on the militant group after two waves of explosions targeted its communications systems, killing 37 people.

Israel carried out dozens of strikes on Thursday across southern Lebanon, three Lebanese security sources told Reuters, saying it was some of the most intense bombing since the start of the war in October.

Hezbollah’s Al Manar TV reported explosions in multiple areas of Lebanon, and a Hezbollah official told The Associated Press that walkie-talkies used by the group exploded as part of blasts heard in Beirut.

Hezbollah turned to low-tech pagers to avoid cellphone tracking by Israeli intelligence. Who else uses pagers, and why?

Pagers used by hundreds of members of Hezbollah exploded almost simultaneously in Lebanon and Syria Tuesday, killing at least 12 people.
