This won't do anything meaningful to reduce civilian deaths. Less than 0.1% of Lebanon injured, and 10x that number now even more enraged. Not meaningfully repeatable either, won't create significant attrition
The massive disruption of Hezbollah's communication network may cripple them enough to shorten the duration of the conflict, and possibly help turn public sentiment from Lebonese civilians into pressure to find a way to end things. The civilians are the people who on average do not feel strongly enough to fight, and may have large number pissed that a group-- even if they believe in its cause-- has brought violence to their communities through a surprise attack against a more powerful enemy. More than half of the Lebonese population believe there is no military solution to the overall dispute: https://www.washingtoninstitute.org/policy-analysis/shadow-h...
Stoking the flames of death is all.
