If you were to consider the fact that Hezbollah has been shelling Israeli cities and civilians on a daily basis for the past 12 months (killing many, also children, and driving hundreds of thousands of people out of their homes), with the UN peacekeeping force failing to keep Hezbollah north of the Litani river - then perhaps you would understand that this is likely as close as you can get to a "precision strike" on an enemy you're at war with.
This may in-fact be the most precise military strike on an enemy paramilitary group in the history of modern warfare.
You either have a very unrealistic idea of what a war actually looks like (0% civilians casualties or injuries), or an agenda.
