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
I wouldn't even shoot a nail gun the opposite direction without safety glasses. People are gonna be blinded or vision impaired by the shrapnel just from happening to shop nearby someone with one of these pagers.
I wonder what modern humane outcome plays out to a tiny nation state surrounded by arabs they're engaged in these kind of hostilities with. It seems this balance depends on large imbalanced external support, which will be called into question more and more as the USA loses global grip.
