If I was wounded (or even witnessed this in real life), I would go from civilian to combatant instantly. Israel just attacked a bunch of civilian population centers. This will be seen as a huge strategic mistake, both in terms of new combatants created on the ground and continued loss of good will for Israel abroad.
I think you are missing context. 10 years of civil war and many more decades of animositiy and of strife, are not reversed overnight , even due to an event like this. For example, Israël has lobbed missiles before, and that had its collateral damage, but also didnt change a thing or win new allies to Hizbullah.
Even some druze (historically neutral sectl were kidnapped and killed in the Oct 7th events.
Now, for the 1st time in 100 years, every single rival of hizbullah is able to instantly recognize enemies, in the open.
Obe thing im certain of, Israel has managed to reset the board in its conflict with Hezbollah.
The only reason IL can do it, is because the general population in Lebanon hates hezbollah, it is basically a proxy control power from IRAN.
Look at this to understand how big part of Lebanon sees Hezbollah https://www.instagram.com/brigitte_gabriel/reel/CyT_RanK1gi/
