As I've remarked several times on this thread, the standard I'm using for this attack isn't one in which no innocents (or even innocent children) are harmed or killed. I don't like war and would happily confiscate every firearm in North America, but that standard is one no active military in the world meets. Rather: the "state of the art" in targeted strikes is air-to-ground weaponry, which routinely kills civilian bystanders at ratios far exceeding 1:1.
Here, my guess is that the ratio is something far south of 1:100, making this strike --- I think? --- unprecedented in precision in the last 100 years of warfare. We'll learn more as the day goes on, and if/when I'm wrong, I'll certainly say so.
"Terrorism" has nothing whatsoever to do with my thinking on this. Hezbollah is a large, sophisticated, organized, well-supplied combatant force, a military peer to its neighbors, and it is in open armed conflict with Israel.
