It’s worth noting that Hezbollah members aren’t just militant fighters.
The SS also included members that weren’t ‘militant fighters’, running a vast economic, political, and charitable apparatus, but few would dispute that attacking members of the SS would be attacking members of a paramilitary organization and legitimate targets.
Only if you assume that all support for the institutions of the SS was in some indirect way ethnic cleansing and genocide.
Do I have to quote Hezbollah’s extensive history of antisemitism and calls for ethnic cleansing of Israel?
I quite literally did.
